Description

A method for registering services, network group center control nodes and systems

technical field

The invention relates to the field of communication technology, in particular to a method for registering a service, a network group center control node and a system.

Background technique

In the existing Internet, there is a brand-new Internet service system with three layers and two domains. It redesigns the Internet architecture into three layers: smart service layer, resource adaptation layer, and network component layer. Introduce their respective entity domains and behavior domains, and design corresponding Internet service methods at the same time, so as to achieve the purpose of Internet to obtain services centered on content. Among them, the service layer of the "three layers and two domains" Internet service system is shown in Figure 1. The principle is: the smart service layer receives the service requirements put forward by users, and according to the service requirements of users, the smart service analysis system in the smart service layer The service parsing server matches the SBD (Service Behavior Description) of each service in the smart service layer, obtains the SID (Service Identifier, service identification) that serves the user, and determines the target location of the server that provides the service according to the SID. In order to obtain the service by sending a request for obtaining the service to the target location, in the new Internet service system of three layers and two domains, only the server providing the service is included as the main body of the service provider. In addition, in the "three-layer two-domain" Internet service system, there is also a router with a storage function. When the router forwards the service content, it will cache part of the service content in itself according to the preset strategy. Routers can provide services for users, but because the services provided by routers are not known to other devices, they are not the subject of service provision. When the router receives and forwards the user's request to obtain the service, which is the same as the SID of the service content stored in its own cache, the router directly returns the service content cached by itself to the user without continuing to forward the service request to the The requested target location.

In the prior art, before the smart service layer receives the service demand from the user, the server providing the service will register the service provided by itself in the service resolution server, so that the service resolution server saves the SID and SBD of all available services. During the service registration process, the service analysis server needs to bind the SID and SBD of the service provided by the service provider, and save the bound SID and SBD in the service analysis server.

In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art:

The service resolution server can only save the binding relationship between the server providing the service and the registered SID and SBD of the service, while many routers with storage functions in the network cannot register the service cached in the router with the service resolution server, so the service The resolution server cannot know the service cached in the router, so when the user queries the service, the service resolution server cannot provide the path corresponding to the path that is closer to the path of the server providing the service where the queried service is located or the bandwidth utilization rate is lower. The address of the router for the service being queried. The router can only match the SID of the service requested by the user when forwarding the request to obtain the service, and if it matches, it will respond to the user's service request and return it to the user without continuing to forward the request to the target location. However, if the router that stores the service requested by the user is close to the user, but not on the forwarding path of the user service request, the user service request will be forwarded to a distant target location, and it is impossible to intelligently transfer the service request from the user near the user. The router that stores the service requested by the user but is not located on the forwarding path of the user service request obtains the corresponding service, which makes the utilization rate of the service in the cache of the router with the storage function low, and cannot efficiently utilize the router with the storage function. The cached service is used to solve the problem of obtaining the service nearby or using the path with low bandwidth utilization.

Embodiment two

An embodiment of the present invention provides a method for registering a service. Referring to FIG. 3 , the method flow includes:

301: When the service stored in the router's cache is changed, the router sends change information to the control node of the network cluster center, wherein the change information includes at least: the router ID, the ID of the change mode, and the service ID and service ID corresponding to the changed service. Behavioral description information.

When the router forwards the service, it chooses to store some services in its own cache according to the preset method. The selected stored service can obtain a certain number of services for the user within a certain period of time. For the router to select the cache service method of the present invention The examples are not limiting. The time of the service cached in the router is short compared to the storage time of the server providing the service, so the service stored in the router will change frequently and be added and deleted continuously. Wherein, the change mode is identified as adding a service or deleting a service.

302: The control node of the network group center receives the change information sent by the router after the service stored in its own cache is changed, wherein the change information at least includes: the router ID, the ID of the change mode, and the service ID and service ID corresponding to the changed service Behavioral description information.

303: The network group center control node updates the service information list stored by itself according to the router ID, the modification mode ID, the service ID corresponding to the changed service, and the service behavior description information corresponding to the changed service in the change information. The service binding information, wherein the service information list is used to save the service identification and service behavior description information corresponding to the service stored in the cache of the router managed by the network group center control node and the router identification corresponding to the router storing the service corresponding relationship.

The control node of the network group center is divided into adding services and deleting services according to the change mode identification in the change information. First, the service information list in the control node of the network group center is updated according to the change information. The service information list includes at least a service identification field, a service behavior description information field, and a storage identification field, which are used to store the identity of the router that stores the service corresponding to the service identification in the network group managed by the control node of the network group center. Each entry in the table saves a unique service, and each field in the service information list saves the service identifier corresponding to the service, service behavior description information, and the router identifier corresponding to the router storing the service.

The process of adding a service is:

3031: When the change mode is identified as adding a service, the network group center control node queries the entry whose service identification field is the service identification in the change information in the service information list stored by itself, wherein the service information Each entry in the list corresponds to a service binding information.

The process of adding a service is divided into two situations. The first one is that the service ID corresponding to the changed service in the changed information already exists in the service information list, and the router ID in the changed information is added to the service table in the service information list. In the storage identifier field of the item, execute step 3032; the second type is that the service identifier corresponding to the changed service in the changed information does not exist in the service information list, then a new entry needs to be created to save it, and step 3033 is executed.

3032: If it exists, update the router identifier in the change information into the storage identifier field of the entry.

3033: If it does not exist, create a new entry in the service information list, use the service identifier in the change information as the service identifier in the service identifier field in the new entry, and use the service identifier in the change information The behavior description information is the service behavior description information in the service behavior description information field in the new entry, and the router in the change information is identified as the content stored in the identification field in the new entry.

The process of deleting a service is as follows:

3034: When the modification mode is identified as deleting the service, the network group center control node queries the service identification field in the service information list stored by itself for the entry of the service identification in the modification information, and in the queried In the storage identifier field corresponding to the entry, it is queried whether only the router identifier in the change information exists, wherein each entry in the service information list corresponds to a piece of service binding information.

The process of deleting a service is divided into two cases. The first one is that there is only one router ID in the storage ID field corresponding to the entry corresponding to the deleted service in the service information list, that is, the router ID in the change information. Only one of the routers managed by the group center control node has this service. After deletion, the service does not exist in the routers managed by the network group center control node. At this time, delete the entry corresponding to the service in the service information list , execute step 3035; the second is that there are multiple router IDs in the storage ID field corresponding to the entry corresponding to the service deleted in the service information list, and at this time, according to the router ID in the change information, the same router ID in the storage ID field will be stored. The router ID is deleted, and step 3036 is executed.

3035: If there is only the router identifier in the change information, delete the entry in the service information list.

3036: If there are other router identifiers, delete the router identifier in the change information in the stored identifier field corresponding to the queried entry.

304: The network group center control node generates a registration request according to the service identification and service behavior description information corresponding to the updated service binding information in the updated service information list and the identity of the network group center control node, and sends the The registration request is sent to the service parsing server for registration, so that the service parsing server sends the service identification and service behavior description information corresponding to the updated service to the network group center control node in the service parsing server according to the registration request The corresponding relationship of the identity identifier is updated.

For the new entry created in step 3033 and the entry deleted in step 3035, it needs to be reported to the analysis server, that is, when a service is added to the router managed by the network group center control node for the first time, step 3041 is executed; the network group center control node When a certain service in the managed router is deleted, but the service does not exist in all the routers, step 3042 is executed. When these two situations occur, the control node of the network group center needs to report to the service resolution server for registration.

3041: When a new entry is created in the service information list, the network group center control node, according to the service identifier in the service identifier field in the new entry, the service behavior description information in the service behavior description information field, and the The identity of the network group center control node generates a registration request for adding services, and sends the registration request to the service analysis server to perform the registration process for adding services;

3042: After the entry is deleted in the service information list, the network group center control node generates a deletion service according to the service identifier in the service identifier field in the deleted entry and the identity of the network group center control node registration request, and send the registration request to the service resolution server to perform the registration process of deleting the service.

Based on the above-mentioned method for registering a service, an embodiment of the present invention also provides a method for obtaining a service, as shown in FIG. 4 , the method flow includes:

401: The terminal sends a service query request to the service parsing server, and the service query request carries keywords of the service query.

402: The service parsing server matches the service behavior description information according to the keyword in the query service request, and stores the service identifier and service behavior description information corresponding to the matched service, as well as the identity identifier of the service provider subject Return to the terminal.

The identity of the service provider can be specifically the identity of the server providing the service and/or the identity of the control node of the network cluster center. Since the queried service may be provided by multiple service providers, it may be returned to the terminal. The identity of a service provider.

403: The terminal sends a request for obtaining a service to the service provider according to the identity of the service provider, wherein the request for obtaining the service includes at least the service identifier and the identity of the service provider.

After the terminal requests the service from the identity of the service provider, the request for service will be forwarded to the destination through various devices in the network. When passing through a router with storage function, the router will pass the service identification in the request Match with the service identifier corresponding to the service cached by itself, and if it matches the router, it will directly return the matched service to the terminal without continuing to forward to the destination address. If there is no match, continue forwarding to the next hop.

404: The network group center control node receives a service acquisition request sent by a terminal, where the service acquisition request includes at least a service identifier.

405: The network group center control node searches the service information list stored by itself for entries whose service identification field is the service identification in the request for obtaining services, and obtains the information in the storage identification field corresponding to the queried items. Router ID.

The acquired router ID can be one or more. If it is one, the request for obtaining the service is directly sent to the router corresponding to the router ID. If multiple router IDs are obtained, one of them can be randomly selected to forward the request for obtaining the service. Routers can also be selected according to certain rules, such as checking whether the working status of the router is busy, and selecting a relatively unbusy router to forward the request for obtaining services to it. It is also possible to forward the service acquisition request to routers corresponding to multiple router identifiers, so that the routers can respectively send services to the terminal.

406: Forward the request for obtaining the service to the router corresponding to the obtained router identifier, so that the router corresponding to the obtained router identifier corresponds to the service identifier in the request for obtaining the service stored in its cache The service is sent to the terminal.

407: The router receives the service acquisition request sent by the terminal forwarded by the network cluster center control node, where the service acquisition request includes at least a service identifier.

408: The router sends the service corresponding to the service identifier in the service acquisition request stored in its own cache to the terminal.

Based on the above method for registering a service, an embodiment of the present invention also provides a method for managing a service, as shown in FIG. 5 , the method flow includes:

501: The network group center control node deletes entries corresponding to services that have not been acquired by the terminal within a preset time from the service information list stored by itself.

The control node of the network group center can also manage the service binding information in the service information list stored by itself, and the services that have not been acquired beyond the preset time can be deleted. After the deletion, it is necessary to register the deletion with the service resolution server, and prompt the router storing the service to delete the service in the cache.

502: The network group center control node generates a registration request for deleting a service according to the service identifier in the service identifier field in the deleted entry and the identity of the network group center control node, and sends the registration request to The service resolution server performs the registration process of deleting the service.
