Problems solved by technology

[0004] However, after the controller generates a group of explicit paths represented by the SID of the message, the ingress node will encapsulate the explicit path into the message, because the explicit path is a fixed path for processing the message, and Encapsulated in the message, so the processing of the message depends on the explicit path for processing, which will lead to low flexibility in processing the message

Abstract

The embodiment of the present application discloses a message processing method, a controller and a forwarding device, which are used to improve the flexibility of message processing. The method in the embodiment of the present application includes: the controller obtains service information, and determines at least one forwarding device according to the service information; the controller generates an instruction list according to the service information and the network function information of the at least one forwarding device, and the The network function information is used to indicate the network function of the at least one forwarding device, and the instruction list includes the control command generated by the controller for the at least one forwarding device; the controller sends the at least one forwarding device Sending a corresponding control instruction in the instruction list, where the control instruction is used to instruct the at least one forwarding device to perform corresponding processing on the service packet of the service corresponding to the service information.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a message processing method, a controller and a forwarding device. Background technique [0002] With the development of network technology, there are more and more data service types, and each data service type has different requirements for network transmission. How to transmit the transmission packets corresponding to each data service type with high quality has become a research focus in the field of network technology. [0003] At present, in order to provide different network transmission requirements for different types of data services, segment routing technology has emerged. The controller obtains the network topology and the segment identifier (SID), then calculates the forwarding path of the message, and transmits a set of explicit paths represented by the SID to the ingress node, namely: segment routing list (segment list), ingress The node will ...
