It should be noted that, an execution subject of the embodiment is a site traffic forwarding device based on SD-WAN, and may also be other devices that can implement the same or similar functions, such as an SD-WAN system, and the like.
It should be understood that the IP address to be forwarded refers to the IP address of the local route under each site, for example, there are two site CPEs, the number of the first site is 3000, the number of the second site is 3001, and the IP address of the local route under the first site includes, but is not limited to, 192.168.4.0/24 and 192.168.3.0/24, while the IP address of the local route under the second site includes, but is not limited to, 192.168.1.0/24 and 192.168.0.0/24, and at this time, 192.168.1.0/24, 192.168.0.0/24, 192.168.1.0/24 and 192.168.0.0/24 are the IP addresses to be issued of the respective sites, and in this embodiment, the site numbers and the IP addresses are in a one-to-many relationship.
It can be understood that the target routing Protocol refers to a Protocol adopted by each site when performing routing publishing, and the target routing Protocol includes a Border Gateway Protocol (BGP), a link state routing Protocol (OSPF), and other routing protocols, in this embodiment, the BGP Protocol is taken as an example for explanation, refer to fig. 3, and fig. 3 is a BGP Protocol encapsulation schematic diagram, which specifically is: the Site number uses Extended Communities Attribute (ECA) in BGP protocol, Type field is Type field, Site information is Site information, refer to section 5 in ietf rfc4360, that is, the value of the Type field high-order octet is 0x00 (IANA-accessible Type, transitive access ASes), and the value of the Type field low-order octet is 0x03(Route Origin Community), that is, the original BGP protocol is modified, specifically, the last 4 bytes of the BGP protocol are used to store the Site number, and encapsulation in the above manner can support 65536 sites.
Further, before step S10, the method further includes: acquiring IP addresses to be issued of all the sites; and automatically learning the site number corresponding to the IP address to be issued through a control plane of a target routing protocol.

And step S50, forwarding the message traffic to be forwarded according to the site number and the configured strategy based on the site.
It should be understood that the site-based policy refers to a policy for forwarding packet traffic to be forwarded, the site-based policy is configured at each site, the site-based policy may be a UDP traffic policy for prohibiting to a site, a TCP traffic speed limit 10M policy for a site, and a WAN1 policy for TCP traffic optimization to a site, and referring to fig. 7, fig. 7 is a schematic diagram of the site-based policy configuration, specifically: the controller is a controller, the Site id is a Site number, and the Site-based policy configured at a Site with the Site number of 3000 is as follows: a site with a site number 3001, and a UDP traffic policy (UDP, drop) prohibited to the site; a site with the site number of 3001 and a TCP traffic speed limit 10M strategy (TCP, 10M) to the site; the site with the site number 3001 and the TCP traffic to the site prefer the WAN1 policy (routing special line), and the site-based policy configured at the site with the site number 3001 is as follows: and after determining the configured strategy based on the sites, forwarding the message traffic to be forwarded to the corresponding sites through the strategy based on the sites.
Further, step S50 includes: judging whether the station has a configured strategy based on the station according to the station number; and when the site has the configured site-based strategy, forwarding the message traffic to be forwarded to the corresponding site through the configured site-based strategy.
It can be understood that the site-based policy is configured at the control plane, that is, after the site number is obtained, it is determined whether the configured site-based policy exists, and if so, the site-based policy is applied, that is, the packet traffic to be forwarded is forwarded through the site-based policy.
In the embodiment, the IP address to be issued of each site and the corresponding site number are encapsulated to the target routing protocol, so that routing data issued to other sites are obtained; other sites establish a mapping relation between a preset IP address and a site number according to the routing data; each station determines a corresponding IP address according to the flow of the message to be forwarded; inquiring the site number corresponding to the IP address according to the mapping relation between the preset IP address and the site number; forwarding the message flow to be forwarded according to the site number and a configured site-based strategy; by the method, each site number is encapsulated to the target routing protocol, and then the message flow is forwarded through the configured strategy based on the site, so that the flow forwarding efficiency can be effectively improved, and the problem of corresponding strategy adjustment caused by the change of the IP address of the site is solved.
