Problems solved by technology
However, in the case of large network traffic that needs to be forwarded, the above-mentioned solution is still difficult to avoid the problem of high bandwidth occupation of the cross-board channel or cross-frame channel, and when the network traffic is large, the bandwidth may even be occupied and forwarding errors may occur. Therefore, the reliability of the frame forwarding device is low

The invention provides a message forwarding method and device, and the method is applied to frame-type forwarding equipment with a plurality of machine frames, and can comprise the steps: determininga candidate output interface which can be used for forwarding a message under the condition that any input interface located on any interface board receives the message; under the condition that the board output interface does not exist and the candidate output interface comprises a cross-board output interface and a cross-frame output interface, if the cross-board channel occupancy rate of any interface board is greater than a preset first occupancy rate and the cross-frame channel occupancy rate of the machine frame to which the interface board belongs is less than a preset second occupancyrate, forwarding the message through the cross-frame output interface; otherwise, forwarding the message through the cross-board outgoing interface. By means of the technical scheme, it can be guaranteed that even if the network flow is large, messages can be forwarded in a preferred cross-board forwarding or cross-frame forwarding mode under the condition that local board forwarding cannot be conducted, and the reliability of the frame-type forwarding equipment is improved to a certain degree.
Description
technical field [0001] The present application relates to the technical field of network communication, and in particular to a message forwarding method and device. Background technique [0002] When a modular forwarding device such as a modular switch forwards packets, since each interface is usually connected to a different network device, inter-board or inter-chassis forwarding of packets often occurs. [0003] In related technologies, the priority forwarding mechanism of the local frame is usually used to reduce cross-frame forwarding, and the cross-board channel bandwidth occupancy rate is reduced by increasing the bandwidth of the cross-board channel or upgrading hardware performance. However, when the network traffic that needs to be forwarded is large, the above-mentioned solution is still difficult to avoid the problem of high bandwidth occupation of the cross-board channel or cross-frame channel, and when the network traffic is large, the bandwidth may even be occu...
