Message forwarding method and related device

Abstract

The embodiment of the invention discloses a message forwarding method and a related device. According to the method, whether the transmission path from the current network equipment to the candidate network equipment is congested or not is judged through the congestion flag bit, so that the non-congested transmission path is found out, the link state can be detected in real time, and path detection and switching can be carried out in time. In addition, the embodiment of the invention can avoid the loop problem through the identifier of the candidate network equipment. The message responds to the network congestion and fault state in real time in the forwarding process, the non-congestion path forwarding is automatically detected, and the message forwarding reliability is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of communications technologies, and in particular, to a method and a related apparatus for forwarding a message. Background technique [0002] figure 1 It is a schematic diagram of packet loss by network devices during traditional packet forwarding. The user connects several network devices through the terminal, and the network device forwards the messages / data packets uploaded by the terminal to each server to complete the data interaction between the terminal and the server. Due to the limited forwarding performance of network devices, some packets are discarded during the forwarding process. The main reason is the buffer overflow of the network device. For example, packets entering from multiple ports are sent out from one port, or a large number of packets entering a high-speed port are forwarded by a low-speed port, and the outgoing port cannot forward the packets in time. Buffering...

Problems solved by technology

The main reason is the buffer overflow of the network equipment. For example, packets entering from multiple ports go out from one port, or a large number of packets entering a high-speed port are forwarded by a low-speed port, and the outgoing port cannot forward the packets in time. Buffering on the outbound port causes buffer overflow on the outbound port, and packets that cannot be cached are dropped.

[0003] Network device packet loss is a very serious network problem that can lead to serious consequences

For example, when a user is watching the live broadcast of the World Cup on the Internet, the discarding of video data will cause delays and freezes in the picture, which will affect the user experience.
