Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0023] see figure 1 As shown, the embodiment of the present invention provides a method for implementing Ethernet protection switching, the method comprising:
[0024] S1. Establish two links between the source end and the sink end to deliver service data configuration, one of which is the active link, and the other link is the backup link. Both the source end and the sink end have The main control protection module, the main link and the backup link are respectively equipped with Ethernet OAM to realize the end-to-end OAM intercommunication of the link;
[0025] S2, Ethernet OAM sends OAM messages in the form of FPGA periodic packets, OAM messages include OAM CV frames for detecting link alarm information and APS frames with Ethernet OAM source link identification address cfm id, OAM CV The frame sending period is 3.33ms. The APS frame of t...
