Problems solved by technology

The existing policy routing method based on application identification is only suitable for applications that can be identified through a single message. Since the signature code of a single message is very small, it is usually identified according to the port that receives the first message; However, most applications in a network using the Transmission Control Protocol (Transmission Control Protocol; TCP for short) often cannot be identified through a single message. Problems in Implementing Policy Routing Based on Application

Abstract

The invention provides a policy routing realizing method, a policy routing realizing device and network equipment. The realizing method comprises the following steps of: storing at least one message sent by a client and identifying the application type corresponding to the at least one message according to the at least one message in the process in which the at least one message is forwarded to aserver according to basic routing information, wherein the basic routing information comprises a first forwarding interface; querying a pre-stored policy routing table according to the application type and acquiring policy routing information, wherein the policy routing information comprises a second forwarding interface; sending a disconnection request message to the server according to the basic routing information to disconnect the client and the server break; and sending the first message in the at least one message to the server according to the policy routing information to establish connection between the client and the server. When the technical scheme provided by the invention is adopted, the policy routing implementing according to any application can be realized.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a strategy routing implementation method, device and network equipment. Background technique [0002] Policy routing is a more flexible packet routing and forwarding mechanism than routing based on the destination network. Based on policy routing, users can not only select a forwarding path according to the destination address of the packet, but also select a forwarding path according to the source address, port, and length of the packet. Policy routing allows packets to be forwarded according to user-specified policies. For example, users can specify that packets from a certain network can only be forwarded to specific ports; another example: for Quality of Service (Qos) requirements or When the virtual private network (Virtual Private Network; VPN for short) topology requires that some packets can only be forwarded through a specific path due to special requirements,...
