Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The first embodiment,
An embodiment of the present invention provides a resource allocation method, which is applied to a network management device, and as shown in fig. 1, the method includes:
step 101: receiving an access request sent by user equipment through first physical client terminal equipment (PCPE), wherein the access request at least carries identification information of the user equipment accessing a virtual local area network;
step 102: determining the access type of the user equipment based on the identification information of the access virtual local area network in the access request;
step 103: allocating communication bandwidth resources for the user equipment based on the access type of the user equipment; if the access type of the user equipment is public access, determining first virtual client terminal equipment corresponding to the first physical client terminal equipment, and controlling the first virtual client terminal equipment corresponding to the first physical client terminal equipment to provide first communication bandwidth resources for the user equipment; and if the access type of the user equipment is a private access type, controlling to provide a second communication bandwidth resource for the user equipment based on the first physical client terminal equipment.
In this embodiment, the first communication bandwidth resource and the second communication bandwidth resource may have different bandwidths. For example, when the first physical client terminal device can provide 10M bandwidth, 2M communication bandwidth resources may be allocated for the first communication bandwidth resource, and 8M bandwidth may be allocated for the second communication bandwidth resource; correspondingly, the user equipment is accessed to the first virtual client terminal equipment through the first communication bandwidth resource of the first physical client terminal equipment, and then the first virtual client terminal equipment transmits the data of the user equipment to the network management equipment for processing by the network management equipment.
Further, before executing the above step 101, the following processing is also executed on the network management apparatus side: the setup is for at least one virtual client terminal device, wherein each of said virtual client terminal devices corresponds to at least one physical client terminal device.
Virtual Customer Premises Equipment (VCPE) is an important scenario for network function virtualization NFV. The virtual customer premises equipment (also called soft CPE, cloud CPE) refers to a network in which three-layer functions and higher-layer service processing functions in the customer-side gateway device are moved up, and the three-layer or more functions of the original Physical Customer Premises Equipment (PCPE) are realized by a virtualization function platform located in the cloud, so that the original customer premises equipment is simplified into a bridge device mainly having two-layer functions.
As shown in fig. 2, the system according to the embodiment of the present invention includes a user-side device PCPE, a network-side device VCPE, and a control plane for which a network management device is responsible.
The control plane of the network management equipment controls the PCPE and the VCPE simultaneously to perform cooperation between the PCPE and the VCPE. The virtual customer premises equipment may be constituted by one or more devices in the data centre of the equipment provider.
First, the PCPE may be set up as a device with two SSID subnets, which may be private (private) SSID and Public (Public) SSID subnets, respectively. The private SSID subnet is used by the user, and the public SSID subnet provides public access for outdoor personnel.
Further, different subnet access types may be identified using different Virtual Local Area Networks (VLANs). The control plane informs the PCPE and VCPE of the VLANs used by the public SSID and the private SSID. When the user equipment accesses the PCPE through different SSIDs, the data packets of the user equipment are marked to be different VLANs. The data packet of the user is sent to the VCPE through the PCPE, then the VCPE sends the data packet of the user to the network management equipment, the network management equipment processes the data packet of the user, and the network management equipment can be distinguished as a private user or a public user according to the VLAN number of the network management equipment. The data packet priority of VLAN corresponding to Public SSID is lower than that of VLAN corresponding to Private SSID, namely, the service priority of Private user is ensured to be higher than that of Public user all the time. The subsequent service chain customized by different VLAN users may also be different, and the network management device can distinguish the service chain customized by the user according to the VLAN.
Preferably, the scheme provided in this embodiment further includes a process that a network management device authenticates a user equipment in an initial stage of establishing a connection with the user equipment, and the method further includes:
controlling the first virtual client terminal equipment to authenticate the user equipment and acquiring an authentication result;
if the authentication result represents that the user equipment passes the authentication, controlling the first virtual client terminal equipment corresponding to the first physical client terminal equipment to provide wireless shared resources for the user equipment;
and if the authentication result represents that the authentication of the user equipment fails, rejecting the user equipment to obtain the wireless shared resource in a public access type through first physical client terminal equipment.
The authentication may be performed by the network management device based on an identifier of the user equipment, for example, after the identifier of the user equipment is obtained, it is determined whether the user equipment performs registration of a service using the virtual client terminal device on the network side, if the registration is determined, the authentication is passed, otherwise, the authentication fails.
Or, the authentication may be executed from the following party to the virtual client terminal device, and after obtaining the identifier of the user device, it is determined whether the user device performs registration of a service using the virtual client terminal device on the network side, and if the registration is determined, the authentication is passed, otherwise, the authentication fails.
Therefore, by adopting the scheme, the access type of the user equipment can be determined based on the access request sent by the user equipment through the physical client terminal equipment, and then whether the communication bandwidth resource is provided for the user equipment through the virtual client terminal equipment is determined based on the access type of the user equipment. Therefore, the network management equipment is used for uniformly controlling the physical client terminal equipment and the virtual client terminal equipment, so that the user equipment can be ensured to be accessed into communication bandwidth resources in a private mode and a public mode, and the physical client terminal equipment can be ensured to still ensure the service quality aiming at private user services.
In addition, by adopting the scheme, on one hand, the physical customer terminal equipment can still be ensured to process the internet access request of the fixed network home broadband user, and on the other hand, the virtual customer terminal equipment provides CPE and AC functions to ensure that the user equipment obtains communication bandwidth resources in a public wireless access mode.
Example II,
An embodiment of the present invention provides a resource allocation method, which is applied to a network management device, and as shown in fig. 1, the method includes:
step 101: receiving an access request sent by user equipment through first physical client terminal equipment (PCPE), wherein the access request at least carries identification information of the user equipment accessing a virtual local area network;
step 102: determining the access type of the user equipment based on the identification information of the access virtual local area network in the access request;
step 103: allocating communication bandwidth resources for the user equipment based on the access type of the user equipment; if the access type of the user equipment is public access, determining first virtual client terminal equipment corresponding to the first physical client terminal equipment, and controlling the first virtual client terminal equipment corresponding to the first physical client terminal equipment to provide first communication bandwidth resources for the user equipment; and if the access type of the user equipment is a private access type, controlling to provide a second communication bandwidth resource for the user equipment based on the first physical client terminal equipment.
In this embodiment, the first communication bandwidth resource and the second communication bandwidth resource may have different bandwidths. For example, when the first physical client terminal device can provide 10M bandwidth, 2M communication bandwidth resources may be allocated for the first communication bandwidth resource, and 8M bandwidth may be allocated for the second communication bandwidth resource; correspondingly, the user equipment is accessed to the first virtual client terminal equipment through the first communication bandwidth resource of the first physical client terminal equipment, and then the first virtual client terminal equipment transmits the data of the user equipment to the network management equipment for processing by the network management equipment.
Further, before executing the above step 101, the following processing is also executed on the network management apparatus side: the setup is for at least one virtual client terminal device, wherein each of said virtual client terminal devices corresponds to at least one physical client terminal device.
Virtual Customer Premises Equipment (VCPE) is an important scenario for network function virtualization NFV. The virtual customer premises equipment (also called soft CPE, cloud CPE) refers to a network in which three-layer functions and higher-layer service processing functions in the customer-side gateway device are moved up, and the three-layer or more functions of the original Physical Customer Premises Equipment (PCPE) are realized by a virtualization function platform located in the cloud, so that the original customer premises equipment is simplified into a bridge device mainly having two-layer functions.
Preferably, the scheme provided in this embodiment further includes a process that a network management device authenticates a user equipment in an initial stage of establishing a connection with the user equipment, and the method further includes:
controlling the first virtual client terminal equipment to authenticate the user equipment and acquiring an authentication result;
if the authentication result represents that the user equipment passes the authentication, controlling the first virtual client terminal equipment corresponding to the first physical client terminal equipment to provide wireless shared resources for the user equipment;
and if the authentication result represents that the authentication of the user equipment fails, rejecting the user equipment to obtain the wireless shared resource in a public access type through first physical client terminal equipment.
In addition, the present embodiment further provides a description for the user roaming problem with public SSID. For the roaming problem of public SSID users, the scheme further provides a scheme for realizing distributed roaming for user services by utilizing a control plane.
The scenario involving roaming handover can be seen in FIG. 3, assuming that pCPE-1 and pCPE-2 are connected to VCPE-1 and PCPE-3 is connected to VCPE-2. The control plane in the network management device controls all of the pCPEs and VCPEs. It should be noted that the embodiments of the present invention do not limit the types of protocols from the control plane to the pCPE and the VCPE, and all protocols that can satisfy the following flow functions can be used in the embodiments of the present invention.
After the controlling provides the first communication bandwidth resource for the user equipment through the first virtual client terminal device corresponding to the first physical client terminal device, the method further includes:
controlling the user equipment to process a first service through the first communication bandwidth resource;
receiving information that the user equipment enters the coverage range of the user equipment sent by second physical client terminal equipment;
detecting whether the virtual client terminal equipment corresponding to the second physical client terminal equipment is the first virtual client terminal equipment or not to obtain a detection result;
if the detection result represents that the second physical client terminal device corresponds to the first virtual client terminal device, keeping and controlling the first virtual client terminal device corresponding to the first physical client terminal device to provide the first communication bandwidth resource for the user equipment so as to process the first service; if the detection result represents that the second physical client terminal device corresponds to the second virtual client terminal device, establishing a route between the second physical client terminal device and the first virtual client terminal device, and controlling the user equipment to provide a first communication bandwidth resource for the user equipment through the first virtual client terminal device based on the route so as to process a first service.
Wherein the second physical client terminal device is different from the first physical client terminal device.
The coverage area of the user equipment entering the second physical client terminal equipment can be determined by the second physical client terminal equipment through real-time monitoring.
The way of establishing the route between the second physical client terminal device and the first virtual client terminal device may be: and selecting and obtaining at least one routing device based on the connection relation between the second physical client terminal and other devices in the network, and establishing and obtaining a route between the second physical client terminal and the first virtual client terminal based on the at least one routing device.
After said controlling said user equipment to provide first communications bandwidth resources to said user equipment for processing first traffic through said first virtual client terminal device based on said routing, said method further comprises:
and judging whether the user equipment initiates a second service, if so, controlling to switch second service data of the user equipment to second virtual client terminal equipment, and controlling to provide communication bandwidth for the user equipment through the second virtual client terminal equipment so as to process the second service.
Wherein the second service is different from the first service. That is, after the user equipment initiates the second service, the communication bandwidth resource of the user equipment may be switched to the second virtual client terminal equipment corresponding to the second physical client terminal equipment.
The process for a public user to roam from a public SSID connected to pCPE-1 to pCPE-3 is described below in conjunction with FIGS. 3 and 4:
step 401: the user equipment is connected with the public WiFi of the pCPE-1;
step 402: the pCPE-1 reports the public WiFi user flow information to network management equipment, namely a control plane;
step 403: the control plane establishes a flow table, guides the user flow to the VCPE-1 and informs the SFC selected by the user to the VCPE-1;
step 404: VCPE carries on user authentication;
step 405: the user starts the service A, and the VCPE-1 guides the user service A to the SFC selected by the user service A;
step 406: the user roams to pCPE-2; and the pCPE-2 reports the control plane, and the flow is guided to the VCPE-1 according to the flow table of the control plane, so that the user service A continues.
Step 407: a user roams to pCPE-3, the PCPE-3 reports to a control plane, and the control plane issues a flow table to guide flow to VCPE-2;
step 408: the VCPE-2 knows that the user has been authenticated by the control plane and obtains the SFC service chain information it selects.
Step 409: the user service A passes through pCPE-3 to VCPE-2, and the service still needs to be routed back to VCPE-1 to continue its SFC.
Step 410: the user initiates a new service B, the service is transmitted to the VCPE-2 through the PCPE-3, and the VCPE-2 provides a corresponding SFC.
The location of the QoS in the data frame of the Wireless Local Area Network (WLAN) can be seen in fig. 5, where the header of the data frame includes a control bit, a length or identification bit, a plurality of address bits, and a quality of service (QoS) control bit, and the frame includes a frame content with a length of n bits except the header, and further includes a Frame Check (FCS). Wherein: the 802.11e protocol provides QoS support in a WLAN environment, which can be divided into parameterized QoS and prioritized QoS. Parameterized QoS refers to researching the demand situation of real-time services on resources, managing network resources, and implementing a network QoS mechanism based on the demand situation, specifically, the QoS parameters to be improved in a network mainly include the following four items: throughput or bandwidth, delay jitter, packet loss rate or error rate.
In this approach, all devices and applications must request a certain amount of time to transmit their data. The prioritized QoS uses priority levels to indicate QoS requirements. Under this approach, packets are tagged as they enter the network, with the tags being granted by a differentiated forwarding/queuing engine at a device such as a residential gateway. QoS with priority is mainly achieved by EDCA. Parameterized QoS is mainly achieved by HCCA, but when TSPEC admission control is used, parameterized QoS can also be achieved by EDCA.
The scheme provided by the embodiment solves the problem that operators need to open new sites to deploy WiFi access of public users. The operator can provide access service for public WiFi users by enhancing the AP devices deployed at the home or enterprise user side. Considering that the number of the AP devices at the home side and the enterprise side is large and updating and upgrading are complex, the scheme further provides a VCPE concept, namely the complex function of the AP at the user side is moved to the VCPE at the network side, and the VCPE processes different flows of the private user and the public WiFi user.
Therefore, by adopting the scheme, the access type of the user equipment can be determined based on the access request sent by the user equipment through the physical client terminal equipment, and then whether the communication bandwidth resource is provided for the user equipment through the virtual client terminal equipment is determined based on the access type of the user equipment. Therefore, the network management equipment is used for uniformly controlling the physical client terminal equipment and the virtual client terminal equipment, so that the user equipment can be ensured to be accessed into communication bandwidth resources in a private mode and a public mode, and the physical client terminal equipment can be ensured to still ensure the service quality aiming at private user services.
In addition, by adopting the scheme, on one hand, the physical customer terminal equipment can still be ensured to process the internet access request of the fixed network home broadband user, and on the other hand, the virtual customer terminal equipment provides CPE and AC functions to ensure that the user equipment obtains communication bandwidth resources in a public wireless access mode.

The authentication may be performed by the network management device based on an identifier of the user equipment, for example, after the identifier of the user equipment is obtained, it is determined whether the user equipment performs registration of a service using the virtual client terminal device on the network side, if the registration is determined, the authentication is passed, otherwise, the authentication fails.
