Message transmission control method and device and network equipment

Abstract

The invention provides a message transmission control method, a message transmission control device and network equipment. The control method comprises the following steps: the network equipment receives a back pressure message, and the back pressure message carries path information of a congested network message; and the network equipment caches the network message corresponding to the path information in a path queue according to the back pressure message, and carries out back pressure on the path queue. According to the above method, the network equipment receives the back pressure message.According to the invention, which path is subjected to message congestion can be determined according to the path information carried by the back pressure message; therefore, the network message of the congested path is cached in the path queue according to the path information; performing back pressure on the path queue; therefore, the flow and the speed of the network device sending the networkmessage to the downstream device in the congested path are reduced, congestion diffusion and queue head blockage of the downstream device are prevented, and the network device only performs back pressure on the network message on the congested path and does not perform back pressure on other paths, so that the service on other irrelevant paths is not influenced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message transmission control method, device and network equipment. Background technique [0002] Metropolitan Area Network (MAN) refers to a computer communication network that covers cities and their suburbs geographically and provides a comprehensive transmission platform for multi-services in the metropolitan area. It belongs to broadband local area networks. The MAN connects upwards to the backbone network and downwards to the access network, forming a multi-layered network structure consisting of the core layer, aggregation layer, and service control layer from top to bottom, and each layer is connected through a corresponding router. The metropolitan area network is a typical bandwidth convergence network. The interface bandwidth of the router converges and converges layer by layer from top to bottom. There are usually multiple paths for load sharing ...
