Method, device, equipment and system for processing oam information of bearer channel

Abstract

Disclosed in the embodiments of the present invention is a bearer channel OAM information processing method, comprising: receiving, according to a FlexE protocol, a bearer client service flow sent by a sending terminal, the bearer client service flow being obtained after OAM information of a client service is inserted into an original client service flow by the sending terminal; extracting the OAM information from the bearer client service flow; processing the OAM information to obtain a detection result of the bearer channel. Also disclosed in the embodiments of the present invention are a bearer channel OAM information processing apparatus, device, and system.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to a method, device, device and system for processing OAM information of a bearer channel. Background technique [0002] The rapid increase of user network information flow has promoted the rapid development of communication network information transmission bandwidth. The interface bandwidth speed of communication equipment has increased from 10M (unit: bit / second, the same content below) to 100M, and 1G and 10G. Reaching the bandwidth speed of 100G, a large number of 100G optical modules have been commercialized in the market; 400G optical modules have been developed, but the price of 400G optical modules is expensive, exceeding the price of four 100G optical modules, resulting in the lack of commercial use of 400G optical modules In order to transmit 400G services on 100G optical modules, the International Standards Organization defines the Flexible Ethernet ...

[0002] The rapid increase of user network information flow has promoted the rapid development of communication network information transmission bandwidth. The interface bandwidth speed of communication equipment has increased from 10M (unit: bit / second, the same content below) to 100M, and 1G and 10G. Reaching the bandwidth speed of 100G, a large number of 100G optical modules have been commercialized in the market; 400G optical modules have been developed, but the price of 400G optical modules is expensive, exceeding the price of four 100G optical modules, resulting in the lack of commercial use of 400G optical modules In order to transmit 400G services on 100G optical modules, the International Standards Organization defines the Flexible Ethernet (Flex Ethernet, FlexE) protocol. The FlexE protocol bundles multiple 100G optical modules to form a high-speed transmission channel; E.g, figure 1 A schematic diagram of forming a 400G transmission channel for four 100G optical modules through the FlexE protocol, as shown in figure 1 As shown, four 100G optical modules are bundled through the FlexE protocol to form a 400G transmission channel, which is equivalent to the transmission speed of one 400G optical module, and solves the transmission requirements of 400G services without increasing costs

[0003] At present, the FlexE protocol definition can carry 10 Gigabit Ethernet (Gigabit Ethernet, GE), 25GE, 40GE and n*50GE (n is a positive integer) customer rate services, providing flexible transmission channels for customer services, and can meet customer bandwidth needs Flexible adjustment of the size of the transmission channel, however, the FlexE protocol only provides a bearer channel for customers, and does not provide the OAM (Operation Administration Maintenance, OAM) function of the bearer channel for customer business, so it is impossible to monitor the service of the bearer channel in real time quality
