Message forwarding processing method, device, controller and routing and forwarding equipment

Abstract

The present invention discloses a message forwarding processing method, device, controller, and routing and forwarding device, wherein the method includes: acquiring label splicing capability information used to identify whether one or more routing and forwarding devices support label splicing, and / or Or the path identification capability information used to identify whether one or more routing and forwarding devices support path identification; according to the acquired label splicing capability information and / or path identification capability information, issue the information to be forwarded to one or more routing and forwarding devices The forwarding strategy for message forwarding processing, through the present invention, solves the problem that the relevant devices that forward the message in the related art cannot know whether to support the splicing and / or path identification function of SR LIST, resulting in the inability to process the message The problem of performing effective forwarding processing can further achieve the capability information of whether label splicing and / or path identification is supported between devices, and then achieve the effect of packet forwarding processing.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a message forwarding processing method, device, controller and routing and forwarding equipment. Background technique [0002] Segment routing (Segment Routing) is a routing method based on the source address. By superimposing a layer of node information that affects the existing shortest path forwarding outside the data message, it is carried outside the data message, and the message is based on these specified path nodes. The information is forwarded by the shortest path. figure 1 It is a schematic diagram of the main message format of the segment routing in the related technology, such as figure 1 As shown, when the message containing the segment routing header is transmitted in the SR network domain, the network device (generally a router) according to the path information of the specified SR node carried in the segment routing header, according to the Segment operation i...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a message forwarding processing method, device, controller and routing and forwarding equipment, so as to at least solve the problem of not knowing whether to support SRLIST splicing and / or paths between related equipment that forwards messages in the related art The identification function leads to the problem that the packets cannot be effectively forwarded and processed
