detailed description

The method, server and router for load sharing in the embodiment of the present invention are described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , after the service flow is deployed in the gateway (English: gateway, GW for short), the control plane of the service orchestration system is configured, and the control plane sends the route forwarding after the service is scheduled. After the rule is sent to the router, the router generates a policy route according to the forwarding rule. After the data packet of the subsequent user (end user) arrives at the router, the router forwards the packet according to the policy route that was delivered last time, and forwards the packet to the corresponding workflow data plane. Deeper parsing and doing business, and forwarding to the corresponding inline service (third-party application server or application server) for business after parsing and decision-making, after sending the service, sending the data packet to the service provider server. (English: Service Provider Server, referred to as: SP server).

The application server in the embodiment of the present invention may include various types, such as: a security protection server, a video optimization server, a multimedia processing server, and a file processing server, wherein the security protection server, the video optimization server, the multimedia processing server, and the file processing server are all It can be a third-party application (Third APP), for example, the video optimization server can be Skyfire Rocket, the multimedia processing server can be Openwave, the file processing server can be OpenWRT security protection.

Each application server can be multi-instance, and load balancing can be achieved by deploying multiple instances.

In the embodiment of the present invention, the communication configuration information of the application server that the user pre-defined service association is sent by the control plane The data plane includes the communication address IP, the port number, the communication mode, the flow order, and the like of the application server through which the data packet of each predefined service of the terminal needs to flow.

For example, the application server through which a certain predefined service data packet needs to flow is: security protection—video optimization—multimedia processing—file processing, when the data packet of the end user comes, the data plane is controlled according to the data flow. The application server communication configuration information is delivered for each service, for example, security protection, video optimization, multimedia processing, file processing, etc., according to the arranged services.

It should be noted that FIG. 1 is only a schematic diagram of a simple networking. In actual applications, different networking modes exist. The present invention does not limit the specific networking mode.

The load sharing method in the embodiment of the present invention will be described in detail below with reference to FIG. 2 .

Steps 201-203 are processes for the user to access the data flow control plane:

201. The gateway receives an online request of the terminal user.

The online request carries the subscription information (or network parameters) of the UE, such as an International Mobile Subscriber Identification Number (IMSI).

202. The gateway allocates an IP address to the terminal; for example, the gateway allocates an IP address to the terminal user as 192.168.100.100.

203. The gateway sends the online request to the service flow control plane, and the service flow control plane receives the online request of the terminal.

The online request carries the terminal information, which includes the IP address assigned by the gateway to the terminal and the network subscription information of the terminal. After receiving the online request, the control plane performs service scheduling, and sends a forwarding rule to the router. The application server communication configuration information is sent to the target data plane, which is implemented by performing the following steps:

204. The service flow control plane performs service scheduling according to the IP address of the terminal, and generates a forwarding rule.

The service flow control plane performs the decision according to the IP address of the terminal, and sends a forwarding rule to the router to indicate the target data plane when the data packet of the terminal is forwarded, so that the data packets of different terminals are forwarded to different On the data side.

The service flow control plane decides which path to send to the router. The decision is the forwarding rule sent to the router. The forwarding rule includes at least the IP address of the terminal and the IP address of the target data plane.

205. The service flow control plane sends the forwarding rule to the router.

206. The router delivers the policy route according to the forwarding rule.

The router generates a corresponding policy route according to the forwarding rule sent by the service flow control plane. When the router receives the data packet of the terminal (including the uplink data packet of the terminal, or the service provider server (SP server) downlinks to the terminal The data packet can be matched to the policy route, and the data packet of the terminal is sent to the corresponding target data plane.

207. The service flow control plane determines the predefined service of the terminal according to the network subscription information of the terminal, and determines communication configuration information of the application server associated with the predefined service of the terminal.

The service flow control plane determines the predefined services of the terminal according to the network subscription information of the terminal, and determines the communication configuration information of the application servers associated with the predefined services.

Specifically, the control plane stores a predefined service template of multiple terminals (that is, the terminal user), where the predefined service template stores the type of service to be performed by each terminal, for example, the A terminal can be used as a webpage or a firewall. And video services; B terminals can do web and video services.

The service flow control plane determines the predefined service of the terminal from the stored predefined service template according to the network subscription information of the terminal.

Then, according to the predefined service, the communication information of the application server associated with the predefined services is configured.

Specifically, the communication address IP, the port number, the communication mode, the flow order, and the like of the application server are configured for each of the predefined services, and the communication modes include TCP, UDP, SCTP, and ICAP.

For example, when the A terminal is doing video services, set the application server that needs to flow through: security protection—video optimization—multimedia processing—file processing, and set the IP address, port number, and communication of each application server that needs to flow through. the way.

208. The service flow control plane sends the communication configuration information of the application server to the target data plane.

The traffic flow control plane sends the communication configuration information of the application server associated with the predefined service to the target data plane, and when the target data plane receives the data packet of the terminal, parses the data packet according to the application server associated with the predefined service. The communication configuration information is done in one application server.

209. After the user goes online successfully, the service flow control plane returns a successful online response to the gateway;

The service flow control plane sends a forwarding rule to the router, and sends the application server communication configuration information associated with the predefined service to the target data plane, and then returns the user online success response message to the gateway.

In 2010, the gateway returns a user attach success response to the terminal;

In 2011, the terminal sends a user data packet to access the service, and sends the data packet to the gateway. The data packet is the uplink data packet of the terminal.

In 2012, the router receives the data packet of the terminal sent by the gateway, matches the policy route in step 206, forwards the packet according to the matched routing table, and sends the data packet to the target data plane for decision.

After receiving the data packet, the target data plane performs a seven-layer analysis to determine the predefined service matched by the data packet, and finds the need according to the communication configuration information of the application server associated with the predefined service received in step 208. When the service is performed on the inline service, the data packet is sent to the corresponding application server, and the service is performed on one application server.

Then, when the data packet determined by the data plane belongs to the video service exemplified in step 207, the data plane performs each service according to the application server communication configuration information sent by the data flow control plane, security protection, video optimization, multimedia processing, Document processing, etc. are done one by one according to the arranged business.

Specifically, after completing the business on one application server, return to the target data surface and then do business on another application server.

In step 2014-step 2015, the target data plane sends the data packet to the application server 1 for service, and after completing the service, returns to the target data plane.

Step 2016-Step 2017 is that the target data plane sends the data packet to the application server 2 for doing business, and after completing the business, returns to the target data plane.

2018. After the target data plane completes the service on the corresponding application server according to the communication configuration information of the application server associated with the predefined service, the data packet is sent to the router, and the router sends the data packet to the service provider server (SP). Server).

Step 2019 - Step 2014: Conversely, the data packet of the service provider server from the downlink to the terminal is opposite to the uplink processing. As shown in FIG. 2, the data packet returned by the service provider server is first sent to the router, and the step is matched to the step. The policy routing in 206 (the data packet received by the router is a service packet from the server to the terminal), and is forwarded according to the matched routing forwarding table, and the data packet is sent to the target data plane for decision. . The target data plane then decides whether to do the inline service according to the communication configuration information of the associated application server, and if necessary, goes to the corresponding application server to do the service, and after completing the service, returns to the router, and the router sends the data packet again. To the terminal.

In the prior art, after the gateway or other device is routed to the router, the general route forwarding can only be forwarded according to the configuration, and the intelligent forwarding cannot be implemented. Therefore, the route cannot be load-sharing. In the embodiment of the present invention, after the service flow control plane performs service orchestration, the router routes are instructed, and the router generates a policy route. After the subsequent packets arrive at the router, the router selects the route and forwards the data to the corresponding data plane for service processing, so that the policy route generated by different users is not Similarly, the forwarding of the device to the data plane is different, thus achieving load sharing. road

In addition, when the service flow control plane configures the application server communication configuration information for the predefined service, the correspondence between the terminal and the specific application server (Inline Service) instance can be controlled, and the correspondence can be flexibly adjusted according to the actual situation of the service. Dynamically tuned to enable load sharing among multiple inline sevice instances of the same type.

In the embodiment shown in FIG. 2, when the traffic flow control plane sends the forwarding rule to the router, it is a forwarding rule generated for a single terminal, and the source IP address (terminal IP address) of the forwarding rule includes only the IP of a single terminal.

Optionally, in the embodiment of the present invention, the service flow control plane may not only deliver a single IP address to the policy route to implement load sharing, but also may send the area address, that is, the band mask as the load sharing. The forwarding rule includes an IP address segment to which the IP address of the terminal belongs, and an IP address of the target data plane, which is used to indicate that the data packet sent by the terminal in the IP address segment to which the IP address of the terminal belongs is forwarded to the same target data plane. For example, if the IP address of the terminal that sends the online request is 192.168.100.100 and the forwarding rule is sent by the service flow control plane, the source IP address is 192.168.0.0/16, indicating that the IP address of the terminal user starting with 192.168 is forwarded to the same Target data surface.
