Problems solved by technology

However, since a network device usually includes multiple service boards, when all packets are sent to the same service board, the processing pressure of this service board is very high and consumes a lot of resources, while other service boards are in an idle state, and a large number of resources are idle

Abstract

The present application provides a message transmission method and device, the method comprising: receiving a first message; judging whether there is a sub-flow table corresponding to the first message; if so, from the sub-flow table corresponding to the first message Obtain the information of the service board in the flow table, and send the first message to the service board corresponding to the information of the service board; if not, select the target service board from multiple service boards, and send the first message to send the message to the target service board, and receive the subflow table corresponding to the second message sent by the target service board; the second message is a message obtained after the first message is converted by NAT, and the second message is converted by NAT The sub-flow table corresponding to the second message includes source information and destination information of the second message, and information of the target service board. Through the technical solution of the application, the resources of each service board are fully utilized, the processing performance of the service board is improved, and the processing pressure of a certain service board is avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message transmission method and device. Background technique [0002] The network equipment of the distributed system architecture (such as routers, switches, and firewalls) can be composed of equipment racks and plugboards on the equipment racks. The types of plugboards can include: main control boards, interface The boards are connected through the switching network. Among them, the main control board is responsible for the management and version upgrade of the interface board and the service board; the interface board is responsible for receiving and sending the message; the service board is responsible for the business processing of the message, such as security business processing, NAT (Network Address Translation, Network Address Translation) processing etc. [0003] In order to implement the NAT processing function, after the interface board receiv...
