Protection switching system and method for wavelength division multiplexing load client network

Abstract

The utility model discloses a protection switching system and a method used for the wave division multiplex (WDM) loading client net. The system comprises the first protector which is used to bypass the signals inputted from the first client's equipment and sent respectively to the service channel and the protection channel; the service channel consists of M serial waveform division devices whichare adopted to transfer the shunting signals to the second protector; the protection channel consists of M serial waveform division devices which are adopted to transfer the shunting signals to the second protector; the second protector is used to receive the signals from the service channel or the protection channel and the received signals can be delivered to the second client's equipment. The utility model introduces the WDM client interface interconnect protocol which effectively solve such problems as the protection switching when the different waveform division devices are interconnected as well as the thoroughly end joint of the client interface. The utility model has the advantages of simple technical solution, feasibility and cost-saving. Also, the stability and the interconnection of the network can be achieved via the utility model.

Description

technical field [0001] The invention relates to the communication field, in particular to a protection switching system and method for wavelength division multiplexing bearer customer network. Background technique [0002] At present, in the communication network, it is usually necessary to interconnect WDM devices of different manufacturers through customer interfaces. However, due to the different methods of handling customer services of each manufacturer in different situations, the WDM devices of different manufacturers are not connected when the customer interfaces are connected. Can be fully connected, resulting in the inability to realize some functions, or even intercommunication. [0003] FIG. 1 shows a diagram of a connection mode between a WDM device and a client device. As shown in Figure 1, the WDM equipment is interconnected with other WDM equipment or customer equipment through the WDM OAC (Optical Adaptation Channel) interface, and the services accessed from...
