Fig. 1A is a flowchart illustrating an embodiment of a route issuing method according to an exemplary embodiment of the present application; fig. 1B is a schematic diagram of a frame device according to the embodiment shown in fig. 1A, where the embodiment may be applied to a frame device, and the frame device may include multiple service boards. In this embodiment of the present application, the frame device may further include a main control board in addition to the plurality of service boards, and each service board is deployed in a tight coupling manner, and is managed by the main control board in a unified manner, and the main control board issues the route in a unified manner. As different service boards need to process different services, routing table entries required by each service board are different, for example, the service types processed by the service boards may include a load balancing service, a WAF (Web application Firewall, Web application protection) service, and a VPN (Virtual Private Network) service, as shown in fig. 1B, the load balancing board is used to process the load balancing service, the VPN board is used to process a VPN service, and the WAF board is used to process a WAF service. Based on the method, a corresponding route issuing strategy can be formulated for each service type according to network planning and service requirements, the formulated route issuing strategy is configured into the main control board through the terminal, and the main control board issues different routes to each service board according to the route issuing strategy, so that the route table entry on each service board is ensured to meet the service requirements. As shown in fig. 1A, the route issuing method includes the following steps:
step 101: and when the changed route is detected, determining the route type of the changed route, executing step 102 if the changed route is a direct route or a host route, and executing step 103 if the changed route is a static route or a dynamic route.
In an embodiment, when detecting that there is a route update or a route addition in the local routing table entry, the main control board triggers to acquire a changed route. The changed route refers to an updated route or a route added to the route entry, and the number of the changed routes acquired each time may be multiple or one.
In an embodiment, the master control board may determine the routing type through the routing type identifier recorded in the routing table entry. For example, the route type identifier direct represents a direct route, the route type identifier host represents a host route, the route type identifier static represents a static route, and the route type identifier dynamic represents a dynamic route.
Step 102: and transmitting the changed route to all service boards.
In an embodiment, the direct connection route is a route generated according to an IP (Internet Protocol) Address and a network mask after the local interface of the device configures the IP Address, and the host route is a 32-bit route generated by the device according to the local interface IP Address and a learned ARP (Address Resolution Protocol) table. Therefore, the direct connection route and the host route both belong to the interface address of the device and the route of the connected subnet, so that the direct connection route and the host route are not influenced by the route issuing strategy and can be directly issued to all service boards.
Step 103: and extracting the characteristics of the changed route, searching a route issuing strategy by using the characteristics, and acquiring a service board identifier corresponding to the characteristics, wherein the route issuing strategy records the corresponding relation between the route characteristics and the service board identifier.
In one embodiment, the dynamic route is a route learned by the master control board according to a routing protocol, since the static route is a route manually configured by an administrator. Therefore, the static route and the dynamic route need to be issued to the service board according to the actual service requirement of the user, that is, need to be issued to the corresponding service board according to the configured route issuing policy.
In an embodiment, the feature of the changed route extracted by the main control board may be a destination network segment, that is, the main control board may extract the destination network segment of the changed route, search for a route issuing policy by using the destination network segment, and obtain a service board identifier corresponding to the destination network segment.
The destination network segment of each route can be recorded in the route table entry of the main control board.
In an exemplary scenario, for a service board processing a load balancing service, a route belonging to an operator network segment needs to be issued for serving as an operator multilink load, so that a correspondence between the operator network segment and a service board identifier processing the load balancing service can be used as a route issuing policy. The operator network segment may include a connected network segment, a telecommunication network segment, a mobile network segment, etc. After extracting the target network segment from the changed route, the main control board searches for the route issuing strategy by using the target network segment, and acquires the service board identifier corresponding to the operator network segment when the target network segment is found to belong to a certain operator network segment.
In an embodiment, the feature of the changed route extracted by the main control board may be a routing protocol, that is, the main control board may extract the routing protocol of the changed route, search a route issuing policy by using the routing protocol, and obtain a service board identifier corresponding to the routing protocol.
The Routing table entry of the main control board may further record a Routing Protocol (i.e., a Routing source) of each route, for example, the Routing Protocol may include a static Protocol, an RIP (Routing Information Protocol), an Open Shortest Path First (OSPF) Protocol, a Border Gateway Protocol (BGP), an Intermediate System-to-Intermediate System (IS to the Intermediate System) Protocol, and the like.
In another exemplary scenario, for a service board processing the WAF service, a route belonging to a Web server network segment needs to be issued for Web application protection, and since there are many Web segments belonging to the Web server and cannot be listed one by one, a route issuing policy between a Web server network segment and a service board identifier cannot be formulated. The route belonging to the Web server network segment is usually the route learned by the routing protocol, so that the corresponding relation between the routing protocol and the service board identifier for processing the WAF service can be used as a route issuing strategy. The routing protocol corresponding to the service board identifier for processing the WAF service may include RIP, OSPF protocol, BGP, and IS-IS protocol. After extracting the routing protocol from the changed routing, the main control board searches for the routing issuing strategy by using the routing protocol, and when the routing protocol is searched, the main control board obtains the service board identification corresponding to the routing protocol.
In an embodiment, the feature of the changed route extracted by the main control board may be a route label, that is, the main control board may extract the route label of the changed route, search for a route issuing policy by using the route label, and obtain a service board identifier corresponding to the route label.
The routing table entry of the main control board may further record a routing label (i.e., a routing tag) of each route, where the routing label in the routing table entry is used for filtering the route, and may be a number or a character, or a combination of a number and a character, and the present application is not limited herein. For example, a route with a route label of 100 belongs to a VPN user route.
In another exemplary scenario, for a service board processing a VPN service, a route belonging to a network segment of a VPN user needs to be issued, and since the network segment belonging to the VPN user generally changes, a route issuing policy between the network segment of the VPN user and an identifier of the service board cannot be established. Based on this, the main control board may mark a route label, for example, 100, for each VPN user route to identify that the route belongs to the VPN user route, so that the correspondence between the route label 100 and the service board identifier for processing the VPN service may be used as a route issuing policy. After extracting the route label 100 from the changed route, the main control board searches for a route issuing policy by using the route label 100, and when the route label 100 is found, obtains a service board identifier corresponding to the route label 100.
It is worth mentioning that the above-mentioned feature of the changed route: the main control board can firstly use the target network segment to search the route issuing strategy when the route issuing strategy is searched by using the characteristics, then use the route protocol to search the route issuing strategy when the route issuing strategy is not searched, and then use the route label to search the route issuing strategy when the route issuing strategy is not searched. Those skilled in the art can understand that the present application is not limited to the search sequence of the destination network segment, the routing protocol, and the routing label, and the search sequence may be set according to the actual requirement of the user, for example, the search sequence of the routing protocol first, the destination network segment, and the routing label second may also be used.
Step 104: and sending the changed route to a service board corresponding to the service board identification.
In an embodiment, the service board identifier may be a service board type identifier or a slot location identifier, that is, a slot location number of the service board, as long as different service boards can be distinguished.
The service board type identifier refers to an identifier of a certain service board. For example, the service board 1 and the service board 2 are both used for processing load balancing services, and belong to a load balancing class service board, so that routes belonging to the load balancing services need to be issued to the service board 1 and the service board 2.
As can be seen from the foregoing embodiment, when a changed route is detected, the main control board may determine the route type of the changed route first, and if the changed route is a direct route or a host route, issue the changed route to all service boards; otherwise, extracting the feature of the changed route, searching a route issuing strategy by using the feature, acquiring a service board identifier corresponding to the feature, recording the corresponding relation between the route feature and the service board identifier in the route issuing strategy, and issuing the changed route to the service board corresponding to the service board identifier. Based on the above description, it can be known that, in the present application, each service board is deployed in a frame device in a tight coupling manner, and the main control board searches for a routing issuance policy according to a routing feature and issues a route to each service board, so as to ensure that a routing table entry on each service board can meet service requirements, and thus the frame device can play a role in flexibly managing the service boards according to service requirements.
