Problems solved by technology

[0004] The above policy routing method requires the router to obtain the IP address list corresponding to the network application protocol, and convert the policy routing related to the application protocol into the policy routing based on the destination IP. In fact, it is difficult to accurately obtain the IP address of the network application server, and it needs Routing information conversion, packet forwarding efficiency is not high

Embodiment Construction

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0027] combine figure 1 As shown, a method for implementing policy routing in an Ethernet switch chip disclosed by the present invention includes the following steps:

[0028] A. Receive the IP message and analyze the message characteristics. The message characteristics include at least: source IP address, destination IP address, TCP / UDP source port number, TCP / UDP destination port number, and DSCP value;

[0029] Among them, the source IP address can distinguish different user sources. When performing policy routing based on different user sources, configure the routing information of the corresponding source IP address in the policy routing table; the TCP / UDP port number can distinguish different application types. When performing policy routing based on different network applicati...

Abstract

The invention discloses a method and device for realizing policy routing in an Ethernet switch chip, which relates to the technical field of network communication, and solves the problem that the message forwarding efficiency is low since the existing policy routing needs to obtain the IP (Internet protocol) address of a network application server and perform routing information conversion. The method disclosed by the invention comprises the following steps of: configuring a policy routing table based on the information such as a message source-based IP address, a TCP / UDP (transmission control protocol / user datagram protocol) source port number, a TCP / UDP destination port number, a DSCP (differentiated services code point) value and the like to obtain the second exit information of corresponding policy routing; and searching a common routing table to obtain corresponding first exit information. The method and device disclosed by the invention can conveniently realize policy routing based on different user sources, different network applications and different service quality requirements, and also can flexibly select the common routing result information or policy routing information; and the realization is simple, the system cost is low, and the routing flexibility and message forwarding efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for implementing policy routing in an Ethernet switch chip. Background technique [0002] The traditional routing method of Ethernet is to use the routing table to forward packets according to the destination IP address. In recent years, with the rapid development of Internet technology, more and more applications are carried on the network, such as video, voice, P2P applications, etc., and traditional routing methods cannot be flexibly forwarded according to different application types. Policy routing is a more flexible data packet routing and forwarding technology. It can not only route and forward according to the traditional destination IP address, but also perform routing and forwarding according to the source IP address, TCP port number, UDP port number, DSCP and other information of the packet. . [0003] The current technology generally...
