Detailed Description
The method, server and router for load sharing according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, in the embodiment of the present invention, a Service flow (workflow) is deployed behind a Gateway (GW), and then the gateway serves as a control plane of a Service orchestration system, the control plane determines Service orchestration, and then issues a routing forwarding rule to a router, the router generates a policy route according to the forwarding rule, after a data packet of a subsequent user (terminal user) reaches the router, the router forwards the packet according to the policy route issued last time, and forwards the packet to a corresponding workflow data plane for further analysis and Service, and forwards the packet to a corresponding inline Service (third party application Server or application Server) for Service according to the analysis and the decision, and after the Service is completed, sends the data packet to a Service Provider Server (SP Server).
The application server in the embodiment of the present invention may include various types, for example: the system comprises a security protection server, a video optimization server, a multimedia processing server, a file processing server and the like, wherein the security protection server, the video optimization server, the multimedia processing server and the file processing server can be Third-party applications (Third APPs), such as: the video optimization server can be Skyfire socket, the multimedia processing server can be Openwave, and the file processing server can be OpenWRT security protection.
Each application server may be multi-instance, and load balancing may be achieved by deploying multiple instances.
The embodiment of the invention also sends the communication configuration information of the application server associated with the predefined service of the user to the data plane through the control plane, wherein the communication configuration information comprises the communication address IP, the port number, the communication mode, the flow sequence and the like of the application server through which the data message of each predefined service of the terminal needs to flow.
For example: the application servers through which the data messages of a certain predefined service need to flow are: when the data message of the terminal user comes, the data plane performs each service according to the communication configuration information of the application server issued by the data flow control plane, for example: security protection, video optimization, multimedia processing, file processing, etc. are done one after another according to the choreographed service.
It should be noted that fig. 1 is only a schematic networking schematic diagram, in practical applications, different networking modes may exist, and the present invention does not limit a specific networking mode.
The load sharing method in the embodiment of the present invention is described in detail below with reference to fig. 2.
Step 201 and 203 are the flow of the user network access data flow control plane:
201. a gateway receives an online request of a terminal user;
the on-line request carries subscription information (or network parameters) of the UE, such as an International Mobile Subscriber Identity (IMSI).
202. The gateway allocates an IP address to the terminal; for example: the gateway assigns the end user an IP address of 192.168.100.100.
203. The gateway sends an online request to a service flow control plane of the terminal user, and the service flow control plane receives the online request of the terminal;
the on-line request carries terminal information, wherein the terminal information comprises an IP address distributed to a terminal by a gateway and network subscription information of the terminal, after receiving the on-line request, a service flow control plane performs service arrangement, issues a forwarding rule to a router, and issues application server communication configuration information to a target data plane, and the method is realized by specifically executing the following steps:
204. the service flow control surface performs service arrangement according to the IP address of the terminal to generate a forwarding rule;
the service flow control surface makes a decision according to the IP address of the terminal, and indicates a target data surface when the data message of the terminal is forwarded by issuing a forwarding rule to the router, so that the data messages of different terminals can be forwarded to different data surfaces when coming.
The service flow control plane decides what path to send to the router, the decision is the forwarding rule sent to the router, and the forwarding rule at least comprises 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 issues a policy route according to the forwarding rule;
the router generates a corresponding policy route according to a forwarding rule issued by the service flow control surface, and when the router receives a data message of the terminal (including an uplink data message of the terminal or a data message of a service provider server (SP server) downlink to the terminal), the router can be matched with the policy route and sends the data message of the terminal to a corresponding target data surface.
207. The service flow control surface determines the predefined service of the terminal according to the network subscription information of the terminal and determines the communication configuration information of an application server related to the predefined service of the terminal;
besides issuing the forwarding rule to the router, the service flow control plane also 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 server related to the predefined services.
Specifically, the control plane stores predefined service templates of multiple terminals (i.e. terminal users), where the predefined service templates store types of services to be performed by each terminal, for example: the terminal A can be used for web page, firewall and video service; the terminal B can be used for webpage and video service.
And the service flow control surface determines the predefined service of the terminal from the stored predefined service template according to the network subscription information of the terminal.
And then configuring the communication information of the application servers associated with the predefined services according to the predefined services.
Specifically, a communication address IP, a port number, a communication mode, a flow sequence, and the like of the application server are configured for each predefined service, where the communication mode includes TCP, UDP, SCTP, ICAP, and the like.
For example: when the terminal A is in video service, the application server needing to flow is set as follows: the method comprises the steps of safety protection, video optimization, multimedia processing and file processing, and sets an IP address, a port number and a communication mode of each application server needing to flow through.
208. The service flow control plane sends the communication configuration information of the application server to a target data plane;
and the service 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 message of the terminal, the data message is analyzed to be served in one application server according to the communication configuration information of the application server associated with the predefined service.
209. The user is successfully online, and the service flow control plane returns an online successful response to the gateway;
and after the service flow control surface issues the forwarding rule to the router and issues the communication configuration information of the application server associated with the predefined service to the target data surface, the service flow control surface returns a response message of successful on-line of the user to the gateway.
2010. The gateway returns a response of successful user attachment to the terminal;
2011. and the terminal sends the user data message access service and sends the data message to the gateway, wherein the data message is the uplink data message of the terminal.
2012. And the router receives the data message of the terminal sent by the gateway, matches the data message with the policy route in the step 206, forwards the data message according to the matched route forwarding table, and sends the data message to a target data plane for decision making.
2013. After receiving the data packet, the target data plane performs seven-layer parsing to determine a predefined service matched with the data packet, and according to the communication configuration information of the application server associated with the predefined service received in step 208, if it is found that a service needs to be performed on an application server (inline service), the data packet is sent to the corresponding application server, and the services are performed next to each other on one application server.
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 communication configuration information of the application server issued by the data flow control plane, and security protection, video optimization, multimedia processing, file processing, and the like are performed one by one according to the arranged services.
Specifically, after the service is done on one application server, the target data plane is returned, and then the service is done on another application server.
Step 2014-step 2015 is that the target data plane sends the data message to the application server 1 for service, and after the service is completed, the data message returns to the target data plane.
Step 2016-step 2017, the target data plane sends the data message to the application server 2 for service, and after the service is finished, the data message returns to the target data plane.
2018. And after the target data plane finishes the service on the corresponding application server according to the communication configuration information of the application server associated with the predefined service, sending the data message to the router, and sending the data message to a service provider server (SP server) by the router.
Step 2019-step 2014: on the contrary, the processing of the data packet from the service provider server to the terminal in the downlink direction is opposite to the processing in the uplink direction, as shown in fig. 2, the data packet returned by the service provider server is first sent to the router, and is matched to the policy routing in step 206 (at this time, the data packet received by the router is the service packet from the server to the terminal in the downlink direction), and the data packet is forwarded according to the matched routing forwarding table, and is sent to the target data plane for decision making. And the target data plane decides whether to make an inline service according to the communication configuration information of the associated application server, if so, makes a service on the corresponding application server, returns to the router after the service is made, and the router sends the data message to the terminal.
In the prior art, after a gateway or other devices route to a router, general routing forwarding can only be forwarding according to configuration, and intelligent forwarding cannot be realized, so that the routing cannot share load. The embodiment of the invention indicates the router to route after the service arrangement is carried out on the service flow control surface, the router generates the strategy route, and the router selects the route to forward to the corresponding data surface to carry out service processing after the subsequent message reaches the router, so that the strategy routes generated by different users are different, and the router forwards to the data surface is different, thereby realizing load sharing. Road surface
In addition, when the Service flow control plane configures the communication configuration information of the application server for the predefined Service, the Service flow control plane can control the corresponding relationship between the terminal and a specific application server (Inline Service) instance, and can flexibly and dynamically adjust the corresponding relationship according to the actual condition of the Service, so that the load sharing can be realized among a plurality of Inline Service instances of the same type.
In the embodiment shown in fig. 2, when the service flow control plane issues the forwarding rule to the router, the forwarding rule is generated for a single terminal, and the source IP address (terminal IP address) of the forwarding rule only includes the IP of the single terminal.
Optionally, in the embodiment of the present invention, the service flow control plane may not only issue a single IP address to the policy routing to implement load sharing, but also issue a domain address, that is, a band mask is used as load sharing. The forwarding rule includes an IP address field to which the IP address of the terminal belongs and an IP address of the target data plane, and is used to instruct the data packet sent by the terminal in the IP address field to which the IP address of the terminal belongs to be forwarded to the same target data plane. For example: the IP address of the terminal sending the online request is 192.168.100.100, and when the service flow control plane issues the forwarding rule, the source IP address is 192.168.0.0/16, which means that the IP addresses of the terminal users beginning with 192.168 are all forwarded to the same target data plane.
The above is a description of an embodiment of a method in the embodiment of the present invention, and a control plane device, a router, and a data plane device in the embodiment of the present invention are described below.
