Abstract

The invention provides a method and a device for main and standby protection of packet transport networking equipment. The method comprises the following steps: router state synchronization is carried out to a first service processing unit in a main state and a second service processing unit in a standby state; and after the first service processing unit and the second service processing unit are subjected to main and standby switching, the second service processing unit carries out service flow data forwarding to the synchronized router information. According to the invention, a timing processing mechanism is adopted to execute router state synchronization, so that after the main and standby switching, the convergence of an MAC (Media Access Control) address and a router address of the standby service processing unit is quicker, thereby improving the main and standby switching performance of the service processing unit.

Description

technical field

[0001] The present invention relates to the field of communications, in particular to a method and device for active / standby protection of packet transmission network equipment. Background technique

[0002] PTN (Packed Transport Network, Packet Transport Network) supports a variety of bidirectional point-to-point connection channels based on packet switching services, and has end-to-end networking capabilities suitable for various fine-grained services. A PTN device is usually composed of an interface unit, a service processing unit and a switching unit, wherein the interface unit completes the access of different data services. There are two types of business processing units, common business processing units and special business processing units. Both business processing units need to complete the encapsulation and sorting of data packets, and the final data will be handed over to the switching unit to complete routing / path selection and forwarding. Due ...
