Embodiment Construction

[0058] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0059] In order to solve the problem that multiple blocked ports easily appear in the ring network existing in the current G.8032v2 forward compatibility, a message processing method provided by the present invention first performs type coding on various types of messages, and adopts "Request / Status" field and / or "Subcode" field for identification, specifically:

[0060] For the NR protocol message, only the "Request / Status" field identifier is used, and the "Request / Status" field identifier of the NR protocol message in the G.8032v2 version is consistent with that in the G.8032v1 version, that is, the identifier is 0000;

[0061] For SF protocol packets, FS protocol packets, and MS protocol packets, the "request / status" field and the "subcode" field are used to identify, and the SF protocol packets, FS protocol pack...

Abstract

The invention discloses a message processing method. In the method, according to a version type supported by nodes on Ethernet and the request / state field of a received message, the nodes unscramble the type of the message under the condition of only supporting G.8032v1 version and process the message according to the unscrambled type; and the nodes unscramble the type of the message according to the request / state field and a subcode field and process the message according to the unscrambled type under the condition of supporting the G.8032v2 version. The invention also discloses a message processing device. By using the method and the device, the problem that a plurality of blocking ports appear on a ring network due to the traditional forward compatible scheme of G.8032v2 is solved and the performance of the Ethernet can be improved.

Description

technical field [0001] The invention relates to the forward compatible technology of the International Telecommunication Union (ITU-T) G.8032v2, in particular to a message processing method and device. Background technique [0002] With the development of Ethernet in the direction of multi-service bearing, especially some services have higher and higher requirements on network reliability and real-time performance, Ethernet widely adopts ring networking to improve network reliability. In the ring network protection method, fast protection switching is generally required, and the protection switching time is required to be less than 50 ms. At present, such rapid protection switching technologies include RFC3619 of the Internet Engineering Task Force (IETF, Internet Engineering Task Force), G.8032 of the International Telecommunication Union (ITU-T, International Telecommunication Union), and the like. [0003] Typical Ethernet ring network protection topology, such as figur...
