Problems solved by technology

[0004] However, due to the need to issue specific policy routing separately for east-west traffic and data packets that do not need to be transmitted through the service chain, the existing technology increases the load pressure on network nodes

Abstract

The embodiment of the present invention proposes a strategy routing delivery method and a network node. The network node judges whether the data belongs to the east-west traffic or the north-south traffic; furthermore, if the data belongs to the east-west traffic, the network node judges whether the data passes the If yes, the network node sends the first policy route of the data, and the configuration data is transmitted through the first service chain path; if not, the configuration data is transmitted through the non-service chain path; on the contrary, if the data belongs to For north-south traffic, the second policy route for data is issued, and the configuration data is transmitted through the second service chain path. Therefore, while ensuring the normal transmission of data, the load pressure on network nodes is reduced by avoiding the delivery of policy routing for data on non-service chain paths.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a method for delivering policy routing and a network node. Background technique [0002] In a network scenario where a campus network or data center references a service chain, there are usually east-west traffic and north-south traffic. The north-south traffic refers to the data packets for internal terminals in the network to access the Internet or for the Internet to access internal terminals in the network. East-west traffic refers to data packets exchanged between terminals within the network. According to different scenario requirements, data packets may be transmitted through different service chains. For example, for east-west traffic, when terminals in the network communicate with each other, due to the requirements of security permissions, the mutual access data packets must pass through the firewall, and at this time, a specific service chain needs to b...
