Problems solved by technology

Although Ethernet can flexibly implement various protections for PTN services and support OTN service protection functions, it cannot meet the performance requirements of large-capacity OTN services for delay and jitter. POTN equipment can only be applied to small-capacity OTN services, and its scope of application is relatively single, which is not convenient for people to use

Abstract

The invention discloses a dual-channel POTN linear protection system, method and device, and relates to the field of a POTN device. The device comprises a dual-channel establishing module, a cell expansion head adding module, a grouping cell determination module, an OTN service protection module and a PTN service protection module. The dual-channel establishing module is connected with the grouping cell determination module through the cell expansion head adding module; and the grouping cell determination module is connected with the OTN service protection module and the PTN service protection module. The dual-channel POTN linear protection system, method and device can be suitable for the high-capacity OTN service, and meanwhile, can realize various protections on PTN services conveniently and flexibly, are not only wide in application range, but also convenient for people to use.

Description

technical field [0001] The invention relates to the field of POTN equipment, in particular to a dual-channel POTN linear protection system, method and device. Background technique [0002] POTN is a packet-based OTN / PTN / SDH (Optical Transport Network / Packet Transport Network / Synchronous Digital Hierarchy) unified switching system equipment. Through the combination of different single disks, POTN equipment can enable OTN / PTN / SDH to integrate with each other and exist independently, thereby providing a unified solution from access to core equipment. [0003] When using POTN equipment, functions such as ring network protection, linear protection, and channel protection need to be implemented. POTN equipment needs to realize OTN / PTN / SDH protection switching within 50ms under the condition of supporting manual seamless switching. For the protection function of the OTN service, the POTN equipment needs to support the 1+1 protection of the electrical layer (the main path and the ...
