and step S101, setting a message service flow type identification rule and a service flow type and global flow identification code corresponding table for a source node through an SD-WAN controller.

Step S103, identifying the message service flow of the source node according to the message service flow type identification rule to obtain the corresponding message service flow type.
It should be understood that the packet service traffic type refers to a type of packet service traffic forwarded from a source node to a destination node, and after the packet service traffic of the source node is obtained, the packet service traffic type corresponding to the packet service traffic can be identified through a packet service traffic type identification rule.
And step S104, inquiring the global flow identification code corresponding to the message service flow type according to the service flow type and global flow identification code corresponding table.
It can be understood that the global traffic identification code refers to a code that determines a node traffic forwarding policy for forwarding a packet traffic, and after a traffic type is obtained, a corresponding global traffic identification code is queried according to a correspondence table between the traffic type and the global traffic identification code, where the global traffic identification code is an extended field, and specifically, the global traffic identification code is encapsulated to a header of the packet traffic, and the global identification codes set for the same type of traffic type are the same.
Step S105, querying a node traffic forwarding policy corresponding to the global traffic identifier according to the global traffic identifier and traffic forwarding policy correspondence table.
It should be understood that after the traffic flow type is obtained, the node traffic forwarding policy is queried through the global traffic identification code and the traffic forwarding policy correspondence table, where the forwarding policy includes a specified link type, a link bandwidth requirement, a link quality requirement, and the like, after the traffic forwarding policy is determined, the traffic forwarding policy is applied to a corresponding node, that is, a source node, and when the traffic forwarding policy is applied, corresponding link quality detection mechanisms need to be enabled at two ends of a tunnel.
And step S106, selecting a source node flow transmission link according to the source node flow forwarding strategy and the link parameters between the source node and the forwarding node.
It can be understood that, after the source node traffic forwarding policy is obtained, the requirement for transmitting the packet traffic is determined according to the source node traffic forwarding policy, for example, a dedicated transmission link is required, but there are multiple dedicated transmission links determined according to the source node traffic forwarding policy, and each corresponding delay is different, and then a transmission link with the lowest delay is selected as the source node traffic transmission link according to the link parameters.
Further, step S106 includes: obtaining a corresponding source-to-link type and a source-to-link dynamic index according to the link parameter between the source node and the forwarding node; determining a source node flow transmission link list according to the source node flow forwarding strategy and the source link forwarding type; and selecting a source point flow transmission link from the source node flow transmission link list according to the source-to-link dynamic index.

It can be understood that the source node traffic transmission link list refers to a list formed by links satisfying the traffic flow requirement of the transmission packet, and then an optimal transmission link is selected from the source node traffic transmission link list according to the dynamic index of the source-to-link, that is, the source node traffic transmission link, for example, the transmission link determined by the source node traffic forwarding policy is a dedicated link and needs low time delay, at this time, the source node traffic transmission link list formed by all dedicated link transmission links between the source node and the forwarding node is determined according to the source node traffic forwarding policy, and then the traffic transmission link with the lowest time delay is selected from the source node traffic transmission link list as the source node traffic transmission link.
In the embodiment, a source node is provided with a message service traffic type identification rule and a service traffic type and global traffic identification code correspondence table through an SD-WAN controller; setting a global flow identification code and flow forwarding strategy corresponding table for a source node through the SD-WAN controller; identifying the message service flow of the source node according to the message service flow type identification rule to obtain a corresponding message service flow type; inquiring a global flow identification code corresponding to the message service flow type according to the service flow type and global flow identification code corresponding table; inquiring a node flow forwarding strategy corresponding to the global flow identification code according to the global flow identification code and flow forwarding strategy corresponding table; selecting a source node flow transmission link according to the source node flow forwarding strategy and the link parameters between the source node and the forwarding node; by the method, the SD-WAN controller is used for setting the message service flow type identification rule, the service flow type and global flow identification code corresponding table and the global flow identification code and flow forwarding strategy corresponding table, then identifying the message service flow type, determining the global flow identification code and the node flow forwarding strategy, and finally selecting the source node flow transmission link according to the link parameters between the source node flow forwarding strategy source node and the forwarding node, so that the accuracy of selecting the source node flow transmission link can be effectively improved.
In an embodiment, as shown in fig. 6, the third embodiment of the SD-WAN-based link selection method according to the present invention is proposed based on the first embodiment, and the step S30 includes:
step S301, de-tunneling encapsulation is carried out on the encapsulated message service flow to obtain a global flow identification code.
It can be understood that, after receiving the encapsulated packet service traffic sent by the source node, the forwarding node needs to perform tunnel decapsulation on the encapsulated packet service traffic before obtaining the global traffic identification code because the source node encapsulates the global traffic identification code and then sends the global traffic identification code to the forwarding node.
Step S302, inquiring a forwarding node flow forwarding strategy corresponding to the global flow identification code according to the global flow identification code and flow forwarding strategy corresponding table.
It should be understood that, after obtaining the global traffic identification code, the forwarding node queries a corresponding forwarding node traffic forwarding policy through a global traffic identification code and traffic forwarding policy correspondence table set by the SD-WAN controller, where the forwarding node traffic forwarding policy refers to a policy for forwarding packet service traffic from the forwarding node to a destination node, and the forwarding node traffic forwarding policy may be the same policy as the source node traffic forwarding policy.
Step S303, selecting a forwarding node flow transmission link according to the forwarding node flow forwarding strategy and the link parameters between the forwarding node and the destination node or other forwarding nodes.
It can be understood that the link parameters between the forwarding node and the destination node or other forwarding nodes include a link type and a link dynamic index, after the forwarding node traffic forwarding policy is obtained, the forwarding node traffic transmission link list is determined according to the forwarding node traffic forwarding policy, and then the forwarding node traffic transmission link is selected according to the link parameters.
Further, step S303 includes: judging whether other forwarding nodes exist between the forwarding node and a destination node; when the other forwarding nodes do not exist between the forwarding node and the destination node, obtaining a destination link type and a destination link dynamic index according to link parameters between the forwarding node and the destination node; determining a forwarding node flow transmission link list according to the forwarding node flow forwarding strategy and the forwarding target link type; and selecting a forwarding node flow transmission link from the forwarding node flow transmission link list according to the destination link dynamic index.
It should be understood that other forwarding nodes refer to nodes between the forwarding node and the destination node, and before the forwarding node forwards the packet service traffic to the destination node, it needs to determine whether other forwarding nodes exist between the forwarding node and the destination node, and if not, the forwarding node does not need to continuously encapsulate the global traffic identification code, and only needs to select a forwarding node traffic transmission link, where a forwarding link type refers to a type of a transmission link between the forwarding node and the destination node, and a forwarding link dynamic indicator refers to a dynamic indicator of a transmission link between the forwarding node and the destination node.
It can be understood that the forwarding node traffic transmission link list refers to a list formed by links meeting the traffic flow requirement of the transmission packet, and then an optimal transmission link is selected from the forwarding node traffic transmission link list according to the dynamic index of the forwarding link, that is, the forwarding node traffic transmission link, for example, the transmission link determined according to the forwarding policy of the forwarding node traffic is Internet, then the transmission link of Internet type is selected according to the type of the forwarding link, and then the transmission link with the highest bandwidth is selected from the forwarding node traffic transmission link list according to the dynamic index of the forwarding link as the forwarding node traffic transmission link.
Further, after determining whether there are other forwarding nodes between the forwarding node and the destination node, the method further includes: when other forwarding nodes exist between the forwarding node and the destination node, obtaining a forwarding link type and a forwarding link dynamic index according to link parameters between the forwarding node and the other forwarding nodes; determining a forwarding node flow transmission link list according to the forwarding link type and the forwarding node flow forwarding strategy; carrying out routing query on a destination address of message service flow to obtain an optional exit link list; screening the forwarding node flow transmission link list according to the optional exit link list; and selecting the flow transmission links of the forwarding nodes from the screened flow transmission links of the forwarding nodes according to the dynamic indexes of the forwarding links.
It can be understood that, when it is determined that there are other forwarding nodes between the forwarding node and the destination node, it indicates that the forwarding node needs to encapsulate the global traffic identification code when forwarding the packet traffic, and before encapsulating the traffic identification code, it needs to determine a forwarding node traffic transmission link of the forwarding node, specifically, a forwarding link type and a forwarding link dynamic index are obtained according to link parameters between the forwarding node and other forwarding nodes, and then a forwarding node traffic transmission link list capable of forwarding the packet traffic is determined according to a forwarding node traffic forwarding policy and the forwarding link type, where a transmission link in the forwarding node traffic transmission link list can only forward the packet traffic to other forwarding nodes, but cannot ensure that other forwarding nodes can reach the destination node, and therefore, after determining the forwarding node traffic transmission link list, and performing routing query according to the destination address to determine transmission links of the selectable outlets, forming a selectable outlet link list according to the transmission links of the selectable outlets, screening the forwarding node traffic transmission link list through the selectable outlet link list, and further selecting the screened forwarding node traffic transmission links according to dynamic indexes of the forwarding links.
Further, after selecting a forwarding node traffic transmission link from the screened forwarding node traffic transmission links according to the dynamic index of the forwarding link, the method further includes: adding a global flow identification code into the tunnel package of the message service flow, and forwarding the packaged message service flow to other forwarding nodes through a forwarding node flow transmission link according to the forwarding node flow forwarding strategy; de-tunneling the encapsulated message service traffic to obtain a global traffic identification code; inquiring other forwarding node flow forwarding strategies corresponding to the global flow identification codes according to the global flow identification codes and flow forwarding strategy corresponding tables; obtaining other link types and other link dynamic indexes according to the link parameters between the other forwarding nodes and the destination node; determining other forwarding node flow transmission link lists according to the other forwarding node flow forwarding strategies and other link types; selecting other forwarding node flow transmission links in the other forwarding node flow transmission link list according to the other link dynamic indexes; transmitting the message service flow to the destination node through the other forwarding node flow transmission link according to the other forwarding node flow forwarding strategy; and when other forwarding nodes exist between the other forwarding nodes and the destination node, repeatedly executing the step of determining the link type and the link parameter.
It should be understood that, after selecting the forwarding node traffic transmission link, the global traffic identification code is continuously added to the tunnel encapsulation of the packet traffic, and similarly, the encapsulated global traffic identification code may adopt GRE encapsulation, VxLAN-GPE encapsulation, or other encapsulation methods, which is not limited in this embodiment, after the encapsulation is completed, the forwarding node forwards the encapsulated packet traffic to other forwarding nodes, and in order to obtain the global traffic identification code, the other forwarding nodes also need to perform de-tunnel encapsulation on the encapsulated packet traffic, then select other forwarding node traffic transmission links according to other link types and other link dynamic indexes, and continuously determine whether other forwarding nodes and the destination node have another forwarding node, if so, the step of determining the link type and the link parameter is repeatedly performed, if not, the message service flow is forwarded to the destination node through other forwarding node flow transmission links.
