Description

Multi-level service deployment and activation method, mobile terminal and readable storage medium

Technical Field

The present invention relates to the field of communication service technology, and in particular to a multi-level service deployment and activation method, a mobile terminal and a computer-readable storage medium.

Background Art

With the rapid development of informatization and mobile Internet, the communication service market is changing with each passing day. Due to the rapid growth in the types and number of mobile devices, the market demand for communication service bandwidth is also increasing, and the types of communication services are becoming increasingly rich. Compared with the closed nature of the traditional vertical architecture of the telecommunications network, the transition of the telecommunications network to a horizontal open architecture will break the closed nature of the telecommunications network, thereby making the telecommunications network ecosystem open, which is not only conducive to reducing the investment and operating costs of operators, but also conducive to achieving network openness, enhancing network elasticity, and promoting the innovative development of telecommunications services.

In the existing multi-layer network service deployment and activation process, the top-level service requires multiple lower-level service connections to be opened, and then deployed and activated based on the existing lower-level service paths. The user manually selects a specific lower-level service from multiple lower-level services to activate the top-level service. When the existing lower-level service does not meet the bandwidth flow requirements, the user is required to recalculate and select the lower-level service. As a result, the entire process is lengthy and complicated, and errors are very likely to occur, resulting in low efficiency in the deployment and activation of multi-layer network services.

The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

Those skilled in the art will appreciate that the terminal structure shown in FIG. 1 does not limit the terminal and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

As shown in FIG. 1 , the memory 1005 as a computer storage medium may include an operating system, a network communication module, a user interface module, and a multi-level service deployment and activation program.

In the terminal shown in FIG. 1 , the network interface 1004 is mainly used to connect to the backend server and perform data communication with the backend server; the user interface 1003 is mainly used to connect to the client (user end) and perform data communication with the client; and the processor 1001 can be used to call the multi-level service deployment and activation program stored in the memory 1005 and perform the following operations:

When the topological connection relationship does not contain the topological connection line that meets the specific constraint conditions of each business layer, the business path deployed in the next layer of each business layer is used as the topological information to generate the target business path of each business layer.

Furthermore, when it is detected that the target service path has been deployed at each service layer of each required service path, the step of opening the multi-layer service includes:

In each required service path, according to the hierarchical relationship of the multi-level services, each service layer is detected layer by layer in turn to see whether the target service path has been deployed;

When it is detected that the target service path has been deployed on each of the service layers of each of the demand service paths, the multi-layer service is opened according to the target service path of each of the service layers.

Further, after the step of opening the multi-layer service when it is detected that the target service path has been deployed in each service layer in each required service path, the method further includes:

When it is detected that the target service path is not deployed in the service layer, each of the service layers that are not deployed with the target service path is extracted for autonomous deployment by the user.

Based on the above hardware structure, an embodiment of the multi-level service deployment and activation method in the present invention is proposed.

2, in a first embodiment of a multi-level service deployment and activation method of the present invention, the multi-level service deployment and activation method includes:

Step S10, obtaining the networking scenarios of the top-level terminals in the multi-level service, and determining the topological connection relationship of the required service paths between the terminals according to the networking scenarios.

According to the service template or resource constraint information selected or input by the user, the networking scenario of each network terminal in the top layer of the current multi-level network service is obtained, and the demand service path between each terminal is analyzed according to the networking scenario, and the topological connection relationship of each network node in each demand service path between each network terminal is determined.

Specifically, for example, in the network service hierarchy diagram shown in FIG5, according to the constraint information input by the user, it is determined that the networking scenario between the four terminals A, X, Y and Z of the top layer L3VPN of the current multi-layer network service is a fully connected scenario, that is, network communication can be achieved between the four terminals A, X, Y and Z, and there are 6 mutually communicating demand service paths between the four terminals A, X, Y and Z. The 6 demand paths in the four terminals are analyzed one by one, and in the current environment network, the topological connection relationship of each node between the A and Z terminals as shown in FIG6 is determined and obtained. The following is explained by taking the topological connection relationship between the A and Z terminals as an example. In the remaining 5 demand service paths, namely, the demand service paths between the A and X terminals, between the A and Y terminals, between the X and Y terminals, between the X and Z terminals, and between the Y and Z terminals, the topological connection relationship analysis between the terminal nodes is the same as the topological connection relationship analysis process between the A and Z terminals, and will not be repeated here.

It should be noted that the networking scenarios of each network terminal include: full connectivity scenario, partial connectivity scenario and single connectivity scenario.

Further, step S10 includes:

Step a: detecting the networking scenario between the terminals in the current multi-layer service deployment requirements of the user, and obtaining the networking scenario.

According to the service templates and service deployment requirements selected or input by the user, the networking scenarios between the network terminals in the top layer of the current multi-layered network service are analyzed and obtained.

It should be noted that when the multi-level service deployment and activation process is started, users can independently select preset service templates, or independently create service templates, and can input corresponding resource constraint information and service deployment requirements based on the independently selected or created service templates.

Specifically, when the user starts the multi-level network service deployment and activation process, the user is prompted to select or create a service template. After the user completes selecting or creating the service template, the user is prompted to enter the service deployment constraint information. For example, when it is detected that the user starts the multi-level network service deployment and activation process, a preset service deployment and activation template is provided to the user. Based on the user's selection operation, the basic network service deployment and activation architecture of the current multi-level service deployment and activation is determined, and the user is prompted to enter the service deployment constraint information. According to the user-input constraint information of "create and deploy L3VPN service between terminal nodes A, X, Y and Z, and the service scenario is a fully connected scenario", the networking scenario between the four terminals of the top level A, X, Y and Z of the current multi-level network service is analyzed as a fully connected scenario, and the fully connected networking scenario is obtained.

Step b: taking each terminal in the networking scenario as a node, determining a topological connection relationship of a demand service path between each node.

On the demand service path between each terminal in the networking scenario between the top-level terminals of the obtained multi-level network service, the location of the terminal is taken as the network node, and the multi-level network service is analyzed according to the network node, and the topological connection relationship between the network nodes in the current environment network.

Specifically, for example, in the network service hierarchy diagram shown in Figure 5, the top level of the multi-level network service is obtained, that is, in the fully connected networking scenario of the L3VPN level, on the demand service path between A and Z among the six demand service paths between the four terminals A, X, Y and Z, with terminals A and Z as network nodes, in the current environment network, the topological connection relationship between nodes A and Z is analyzed according to the network positions of network nodes A and Z.

Step S20: detecting the hierarchical relationship of the multi-level services and the constraint conditions of each service layer, and acquiring specific constraint conditions of each service layer according to the hierarchical relationship and the constraint conditions.

According to the basic level requirements of multi-level network service deployment and the service template selected or created by the user, the number of service levels and the level order relationship contained in the multi-level network service are detected, and according to the service deployment requirements and resource preset conditions input by the user, the preset conditions applicable to each service layer in the multi-level network service are obtained.

It should be noted that the preset constraint conditions are: the constraint conditions that need to be met for the multi-level service deployment and activation that are selected or input by the user in advance.

Specifically, for example, in the network service hierarchy diagram shown in Figure 5, according to the service deployment requirements input by the user: "Create and deploy L3VPN services between nodes A, X, Y and Z, the service scenario is a fully connected scenario, and when deploying L3VPN services, create and deploy BGP-LU, Tunnel, TMS and ODU services. Among them, BGP-LU services must pass through node D, and TMS must pass through node B", the number of service layers included in the current multi-level network service and the hierarchical order relationship between each service layer are analyzed, and according to the service deployment requirements and hierarchical relationships input by the user, the specific constraints applicable to each service layer are adapted layer by layer.

Further, step S20 includes:

Step c: determining the hierarchical relationship of each service layer in the multi-level service according to the basic level required for opening the multi-level service and the level set by the user in the preset constraint condition.

According to the basic level requirements of the multi-level network service deployment and the service template selected or created by the user, the number of service levels and the level order relationship contained in the multi-level network service are detected.

Specifically, for example, in the network service hierarchy diagram shown in FIG5 , according to the service deployment requirements input by the user: "L3VPN services are created and deployed between nodes A, X, Y and Z, and the service scenario is a fully connected scenario. When deploying L3VPN services, BGP-LU, Tunnel, TMS and ODU services are created and deployed, wherein the BGP-LU service must pass through the constraint node D, and the TMS must pass through the node B", it is analyzed that the current multi-layered network services include 5 service layers, namely, network layer-L3VPN services, routing layer-BGP-LU services, protocol layer-Tunnel services, management layer-TMS services and wiring layer-ODU services, wherein the top layer is the network layer-L3VPN service layer, the bottom layer is the wiring layer-ODU service layer, and the order relationship of the remaining intermediate layers is, from top to bottom, routing layer-BGP-LU service layer, protocol layer-Tunnel service layer and management layer-TMS service layer.

Step d: analyzing the specific constraints applicable to each of the business layers in the preset constraints layer by layer according to the hierarchical relationship.

According to the service deployment requirements and resource preset conditions input by the user, the preset conditions applicable to each service layer in each required service path of the multi-level network service are obtained layer by layer.

Specifically, for example, in the network service hierarchy diagram shown in Figure 5, in the required service path between the top-level A and Z terminals, according to the service deployment requirements input by the user: "Create and deploy L3VPN services between nodes A, X, Y and Z, the service scenario is a fully connected scenario, when deploying L3VPN services, create and deploy BGP-LU, Tunnel, TMS and ODU services, among which BGP-LU services must pass through the constraint node D, and TMS must pass through the B node". The service hierarchy relationship is obtained, and the specific constraints applicable to the network layer-L3VPN service layer, the routing layer-BGP-LU service layer, the protocol layer-Tunnel service layer, the management layer-TMS service layer and the wiring layer-ODU service layer are read layer by layer in a top-down order.

Furthermore, step d, analyzing the specific constraints applicable to each of the business layers in the preset constraints layer by layer according to the hierarchical relationship, also includes:

Step d01 , reading preset constraints of each business layer layer by layer in a descending order of the hierarchical relationship.

In the multi-layered network service, according to the deployment requirements input by the user, preset conditions applicable to each service layer in each required service path of the multi-layered network service are obtained layer by layer in sequence.

Step d02, merging the preset constraints of the read business layer itself with the preset constraints of each business layer above the read business layer one by one, generating specific constraints of each business layer read one by one until the bottom business layer.

Specifically, in the network service hierarchy diagram shown in FIG5 , in the required service path between the top-level A and Z terminals, according to the service deployment requirement input by the user: "Create and deploy L3VPN services between nodes A, X, Y and Z, the service scenario is a fully connected scenario, when deploying L3VPN services, create and deploy BGP-LU, Tunnel, TMS and ODU services, among which BGP-LU services must pass through the constraint node D, and TMS must pass through the node B", the service hierarchy relationship is obtained, in a top-down order, read the preset constraints applicable to the network layer-L3VPN service layer, the routing layer-BGP-LU service layer, the protocol layer-Tunnel service layer, the management layer-TMS service layer and the wiring layer-ODU service layer in the deployment requirement layer by layer, and The preset constraints of the business layers above the business layer are added to the preset constraints of each business layer, thereby generating specific constraints of the current business layer. For example, in the business deployment requirements input by the user, the constraints applicable to the network layer-L3VPN business layer are: the business scenario between each terminal is a fully connected scenario. Since the network layer-L3VPN business layer is the top layer and there is no business layer above it, the specific constraints of the network layer-L3VPN business layer are "the business scenario between each terminal is a fully connected scenario". The preset constraints applicable to the routing layer-BGP-LU business layer are: the constrained D node must be passed through, then the specific constraints of the routing layer-BGP-LU business layer are "the constrained D node must be passed through" + "the business scenario between each terminal is a fully connected scenario", and the following layers are deduced by analogy.

Step S30: In each of the required service paths, according to the topological connection relationship and the specific constraint conditions of each of the service layers, the target service paths of each of the service layers are deployed in sequence.

In the demand service paths between the terminals of the current multi-layered network services, the target service paths supporting each service layer are deployed layer by layer in turn according to the topological connection relationship between the terminal nodes in the current environment network and the specific constraints of each service layer of the multi-layered network services.

Specifically, for example, on the demand service path between A and Z among the six demand service paths between four terminals A, X, Y and Z, with terminals A and Z as network nodes, in the current environment network, after analyzing the topological connection relationship between nodes A and Z according to the network positions of network nodes A and Z, according to the number of levels of the multi-level network service and the order relationship between the levels, in order from the top layer to the bottom layer, the specific constraints of each service layer are read layer by layer, and from the topological connection relationship between nodes A and Z, the target service path that meets the specific constraints of the service layer is determined.

Step S40: when it is detected that the target service path has been deployed in each service layer in each required service path, the multi-layer service is activated.

In the demand service path between each terminal, each service layer in the current multi-level network service is detected layer by layer to see whether the target service path has been deployed. When it is detected that the target service path of each layer has been deployed, the current multi-level network service is opened according to the target service path deployed by each service layer.

Specifically, for example, in the network service hierarchy shown in Figure 5, it is detected whether each service layer in the demand service path between A and Z, namely the wiring layer-ODU service layer, the management layer-TMS service layer, the protocol layer-Tunnel service layer, the routing layer-BGP-LU service layer and the network layer-L3VPN service layer, has deployed one or more corresponding target service paths. When it is detected that the wiring layer-ODU service layer, the management layer-TMS service layer, the protocol layer-Tunnel service layer, the routing layer-BGP-LU service layer and the network layer-L3VPN service layer all contain at least one deployed target service path, and each service layer of each demand service path between other terminals contains at least one deployed target service path, the current multi-layer network service is opened according to one or more target service paths and service protection paths of each service layer.

Further, step S40 includes:

Step e: in each required service path, according to the hierarchical relationship of the multi-level services, detecting layer by layer in turn whether each service layer has deployed the target service path.

In each required service path between each terminal in the top layer of the multi-layer network service, it is detected layer by layer whether each service layer has deployed a target service path that meets the specific constraint conditions of the service layer.

Specifically, for example, in the network service hierarchy shown in Figure 5, detect whether each service layer in the demand service path between A and Z, namely the wiring layer-ODU service layer, the management layer-TMS service layer, the protocol layer-Tunnel service layer, the routing layer-BGP-LU service layer and the network layer-L3VPN service layer, has deployed one or more corresponding target service paths.

Step f: when it is detected that the target service path has been deployed on each service layer of each required service path, the multi-layer service is opened according to the target service path of each service layer.

When it is detected that the target service paths of each layer of each required service path between each terminal have been deployed, the current multi-layer network service is opened according to the target service paths deployed at each service layer.

When it is detected that the wiring layer-ODU service layer, management layer-TMS service layer, protocol layer-Tunnel service layer, routing layer-BGP-LU service layer and network layer-L3VPN service layer all contain at least one deployed target service path, and each service layer of each required service path between other terminals contains at least one deployed target service path, the current multi-level network service is opened according to one or more target service paths and service protection paths of each service layer.

In this embodiment, by obtaining the networking scenarios of the top-level terminals in the multi-level service, the topological connection relationship of the required service paths between the terminals is determined according to the networking scenarios; the hierarchical relationship of the multi-level service and the constraints of each service layer are detected, and the specific constraints of each service layer are obtained according to the hierarchical relationship and the constraints; in each required service path, the target service path of each service layer is deployed in sequence according to the topological connection relationship and the specific constraints of each service layer; when it is detected that the target service path has been deployed for each service layer in each required service path, the multi-level service is opened.

The networking scenario of each network terminal in the top layer of the current multi-layered network service is obtained according to the service template or resource constraint information selected or input by the user, and the required service path between each terminal is analyzed according to the networking scenario, and the topological connection relationship of each network node in each required service path between each network terminal is determined. The number of service levels and the hierarchical order relationship contained in the multi-layered network service are detected according to the basic hierarchical requirements of the multi-layered network service deployment and the service template selected or input by the user, and the preset conditions applicable to each service layer in the multi-layered network service are obtained according to the service deployment requirements and resource preset conditions input by the user. In the required service path between each terminal of the current multi-layered network service, according to the topological connection relationship between the terminal nodes in the current environment network and the specific constraint conditions of each service layer of the multi-layered network service, the target service path supporting each service layer is deployed layer by layer in sequence. In the required service path between each terminal, whether the target service path has been deployed for each service layer in the current multi-layered network service is detected layer by layer. When it is detected that the target service path of each layer has been deployed, the current multi-layered network service is opened according to the target service path deployed for each service layer.

It realizes automatic deployment of target service paths that meet the service constraints of each service layer to each service layer based only on the deployment templates of each service layer pre-selected by the user, or by autonomous input of constraint conditions, thus simplifying the tedious operation process of users deploying and opening multi-level network services. It matches the target service path of the required service path based on the networking scenario of each terminal, and opens the entire multi-level network service after ensuring the deployment of the target service path of each service layer and the service protection path set by the user, ensuring the accuracy of the opening, thereby improving the efficiency of multi-level network service deployment and opening.

3 , in the second embodiment of the internal and external antenna switching method of the present invention, based on the embodiment shown in FIG. 2 , step S30 sequentially deploys the target service paths of each service layer in each of the required service paths according to the topological connection relationship and the specific constraints of each service layer, including:

Step S31 , in the required service path between the terminals at the top layer, the specific constraint conditions and service protection paths of each service layer are read layer by layer in a bottom-up order.

In the current demand service paths between terminals of multi-layered network services, specific constraints of each service layer are read layer by layer from top to bottom according to the sequential relationship between the service layers, and the user independently sets the service protection path.

It should be noted that the user can independently set the protection path according to business needs in each business layer of the multi-level network business.

Specifically, for example, in the network service hierarchy diagram shown in Figure 5, the specific constraints of the wiring layer-ODU service layer, the management layer-TMS service layer, the protocol layer-Tunnel service layer, the routing layer-BGP-LU service layer and the network layer-L3VPN service layer are read in sequence from bottom to top, and at a certain service layer, the service protection path set by the user according to the service deployment requirements.

Step S32: based on the topological connection relationship, obtaining the topological connection lines of the service layers that satisfy the specific constraint conditions.

The topological connection relationship between the terminal nodes of the required service path obtained from the current environment network is used as the basic connection line, and the topological connection line that meets the corresponding specific constraint conditions of each service layer is obtained from the basic connection line.

Specifically, for example, in obtaining the topological connection relationship between each node between the A and Z terminals as shown in Figure 6, all connection lines between the terminal nodes A and Z are taken as the basic connection lines, and from the basic connection lines, the topological connection lines that meet the specific constraints of each business layer of the required business path between the A and Z terminals are extracted.

Step S33: Use the topology connection line as the target service path of each service layer, and deploy the target service path and the service protection path together to each service layer.

The topological connection lines of the service layer-specific constraints of the demand service paths between the terminals are read as the target service paths supporting the service layers, and the target service paths and protection paths of the service layers are deployed together to the service layers.

Specifically, for example, in the network service hierarchy diagram shown in Figure 5, the topological connection line that meets the specific constraints of the wiring layer-ODU service layer read from the basic connection line is used as the target service path supporting the wiring layer-ODU service layer. When it is detected that the user has set a protection path at the wiring layer-ODU service layer, the target service path and service protection path of the wiring layer-ODU service layer are jointly deployed to the wiring layer-ODU service layer. When it is not detected that the user has set a protection path at the wiring layer-ODU service layer, the target service path of the wiring layer-ODU service layer is deployed to the wiring layer-ODU service layer. The rest are deployed in order from bottom to top, that is, the management layer-TMS service layer, the protocol layer-Tunnel service layer, the routing layer-BGP-LU service layer and the network layer-L3VPN service layer.

Furthermore, in another embodiment, after obtaining the topological connection lines of each service layer satisfying the respective specific constraint conditions based on the topological connection relationship in step S32, the method further includes:

Step S34, when the topological connection relationship does not contain the topological connection line that meets the specific constraint conditions of each business layer, the business path deployed in the next layer of each business layer is used as the topological information to generate the target business path of each business layer.

When a topological connection line that satisfies the corresponding specific constraints of each business layer is not obtained in the basic connection line based on the topological connection relationship between the terminal nodes of the required business path obtained from the current environment network, the business path of the next layer of the business layer that has been deployed is used as the topology information to directly generate the business path of the current layer.

Specifically, for example, in the network service hierarchy diagram shown in FIG5 , when it is detected that in obtaining the topological connection relationship of each node between the A and Z terminals as shown in FIG6 , the basic connection lines based on all the connection lines between the terminal nodes A and Z do not contain specific constraints on the service deployment that conform to the protocol layer-Tunnel service layer, the target service path of the management layer-TMS service layer that has been deployed is used as the topology information, and the routing calculation algorithm is called to generate a target service path that supports the protocol layer-Tunnel service layer.

Furthermore, in combination with the network service levels shown in FIG. 5 , an optimal implementation of the multi-level service deployment and activation method of the present invention is proposed.

The constraint information for the current multi-layer network service deployment and activation entered by the user is: L3VPN service is created and deployed between nodes A, X, Y and Z. The service scenario is a fully connected scenario. When L3VPN service is deployed, BGP-LU, Tunnel, TMS and ODU services are created and deployed. BGP-LU service must pass through constraint node D, and TMS must pass through node B.

Based on the current multi-layer network service deployment and activation requirements input by the user, the user service configuration data is analyzed, that is, the L3VPN service is specified to be configured, the service scenario is a full connectivity scenario, four nodes A, X, Y and Z are selected, and the UNI interface under each node is configured as needed, and the service parameters are derived from the L3VPN parameter template; the BGP-LU service is specified to be configured, and its scenario is an unprotected service scenario. The service must pass through the D node, and the service parameters are derived from the BGP-LU parameter template; the Tunnel service is specified to be configured, and its scenario is a protected service scenario. The service parameters are derived from the Tunnel parameter template; the TMS service is specified to be configured, and the service must pass through the H node. The service parameters are derived from the TMS parameter template; the ODU service is specified to be configured, and the service parameters are derived from the ODU parameter template.

The current multi-level network service deployment process is as follows:

Step g: Analyze the topological relationship between nodes according to the top-level L3VPN service full-connection scenario. Nodes A, X, Y, and Z are connected to each other, that is, there must be a BGP-LU service path between every two nodes. The following process takes the service path from A to Z as an example, and the service paths of other nodes are similar.

Step h: Analyze the scenario and constraints of BGP-LU. It must pass through node D. Its lower layer service tunnel is separated into two tunnel services, A to D and D to Z.

Step i, analyzing the tunnel service, the scenario is a protection scenario. According to the analysis result of step g, there are two tunnel services: the tunnel service from A to D and the tunnel service from D to Z. There are two service paths, namely, working A to D to Z and protection A to D to Z.

Step j, analyzing the TMS service, which is an unprotected scenario and must pass through node B. According to the analysis result of step 3, A to B to D to Z, A to D to Z is protected.

Step k, analyze the ODU service, which is the lowest level service. According to the analysis result of step j, call the routing algorithm, and calculate two separate paths according to the topological connection relationship of the networking topology diagram of the basic network as shown in Figure 6. They are A to Z, which must pass through B and D; A to Z, which must pass through D.

In step 1, the ODU path calculation results are shown in the figure. The paths are A-B-C-D-E-F-Z and A-G-H-I-J-D-K-L-M-N-Z.

In step m, the path of the TMS is calculated. Its upper layer is separated and protected at node D, so four TMSs from A to D and from D to Z are generated. According to the path results calculated in step k, the results are: A-B-C-D, A-G-H-I-J-D, D-E-F-Z and D-K-L-M-N-Z.

In step n, the tunnel path is calculated. Its upper layer is separated at node D and has protection itself, so four tunnels from A to D and from D to Z are generated. According to the path results calculated in step m, the results are: TMS:A-D(A-B-C-D): TMS:A-D(A-G-H-I-J-D), TMS:D-Z(D-E-F-Z) and TMS:D-Z(D-K-L-M-N-Z).

Step o, calculate the BGP-LU path, which must pass through node D at this layer. According to the path result calculated in step m, the result is Tunnel: A-D, Tunnel: D-Z.

Step p, traverse the connection relationship between other L3VPN nodes, repeat step h, and go to step o.

Step q: Services are deployed and issued sequentially from ODU, TMS, Tunnel, BGP-LU and L3VPN. If the service delivery at a certain level fails, the delivery is stopped immediately and the delivered services are rolled back.

In this embodiment, the specific constraints and service protection paths of each service layer are read layer by layer in the demand service path between the top-level terminals in a bottom-up order; based on the topological connection relationship, the topological connection lines of each service layer that meet the specific constraints of each service layer are obtained; the topological connection lines are used as the target service paths of each service layer, and the target service paths and the service protection paths are deployed together to each service layer; when the topological connection relationship does not contain the topological connection lines that meet the specific constraints of each service layer, the service paths deployed at the next layer of each service layer are used as the topological information to generate the target service paths of each service layer.

By reading the specific constraints of each business layer from top to bottom in the demand business path between each terminal of the current multi-level network business according to the sequential relationship between each business layer, and the user independently setting the business protection path, the topological connection relationship between the terminal nodes of the demand business path obtained from the current environment network is used as the basic connection line, and the topological connection line that meets the corresponding specific constraints of each business layer is obtained from the basic connection line, and the topological connection line of the specific constraints of each business layer of the demand business path between each terminal is read as the target business path supporting each business layer, and the target business path and protection path of each business layer are jointly deployed to the business layer. When the topological connection line that meets the corresponding specific constraints of each business layer is not obtained in the basic connection line based on the topological connection relationship between the terminal nodes of the demand business path obtained from the current environment network, the business path of the next layer of the business layer that has been deployed is used as the topological information to directly generate the business path of the current layer.

It realizes the one-time completion of multiple levels of business deployment without the need for users to configure from the bottom-level business scenario layer by layer. The deployment algorithm of each layer of business path is unified. The lower-level business path is the topology of path calculation provided by the upper-level business path. The business path does not need to traverse the entire network for search, making the path calculation efficiency of each layer of business higher and the calculation result more in line with the user's demand path.

4 , in a third embodiment of the internal and external antenna switching method of the present invention, based on the embodiment shown in FIG. 2 , in step S40, when it is detected that each of the service layers in each required service path has deployed the target service path, after the multi-layer service is opened, the multi-layer service deployment and opening method of the present invention further includes:

Step S50: when it is detected that the target service path is not deployed in the service layer, each service layer where the target service path is not deployed is extracted for the user to independently deploy.

In the required service paths between the terminals, each service layer in the current multi-level network service is detected layer by layer to see whether the target service path has been deployed. When the target service path of one or more service layers detected has not been deployed, the user is prompted that the deployment has failed, and the one or more service layers that have not been deployed are displayed to the user for the user to manually deploy them.

Specifically, for example, in the network service hierarchy shown in Figure 5, each service layer, that is, the wiring layer-ODU service layer, the management layer-TMS service layer, the protocol layer-Tunnel service layer, the routing layer-BGP-LU service layer and the network layer-L3VPN service layer, is detected layer by layer to see whether one or more target service paths have been deployed. When it is detected that the target service paths of the wiring layer-ODU service layer, the management layer-TMS service layer, the protocol layer-Tunnel service layer, the routing layer-BGP-LU service layer and/or the network layer-L3VPN service layer have not been deployed, a prompt message of "deployment failed" is output, and the wiring layer-ODU service layer, the management layer-TMS service layer, the protocol layer-Tunnel service layer, the routing layer-BGP-LU service layer and/or the network layer-L3VPN service layer are displayed to the user, prompting the user to manually select or add a deployed service path.

In this embodiment, when it is detected that the target service path is not deployed in the service layer, each service layer that is not deployed with the target service path is extracted for the user to independently deploy.

By detecting layer by layer in the required service path between each terminal whether each service layer in the current multi-level network service has deployed the target service path, when the target service path of one or more service layers detected has not been deployed, the user is prompted that the deployment has failed, and the one or more service layers that have not been deployed are displayed to the user for the user to manually deploy them independently.

It is achieved that when the target service path that meets the user's deployment configuration information is not detected, the service layer that has not been deployed or has not been fully deployed during the deployment process will be automatically displayed to the user, so that the user can manually configure the service path independently, further improving the accuracy of multi-level network service deployment and activation, and ensuring the security of service activation.
