Embodiment Construction

[0030] The invention provides a device for dynamically adjusting the service protection threshold in an optical transmission system, the structure of which is as follows: figure 1 shown. It consists of a service characteristic information extraction unit 1, a service protection execution unit 2, a service protection control unit 3, a protection threshold adjustment unit 4 and an MCU5, wherein:

[0031] The service feature information extraction unit 1 extracts feature information reflecting whether the service is working normally from the input transmission service, and the extracted feature information is sent to the service protection control unit 3;

[0032] The service protection execution unit 2 performs protection actions on the input transmission services according to the control information sent by the service protection control unit 3 and then outputs them. The specific service it performs is route switching.

[0033] The service protection control unit 3 implements ...

Abstract

This invention relates to a device for dynamically adjusting service protection threshold in an optical transmitting system composed of a service character information pick-up unit1, a service protection executing unit2, a protection control unit3, a protection threshold regulating unit4 and MCU5, in which, module 1 picks up related character information from input transmission service and transmits it to module 3, module 2 protects the input transmission service according to the control information sent by module 3 and outputs it, module 3 decides a protection decision based on the information provided by modules 1 and 4 and sends the result to module 2, which carries out dynamic adjustment to the protection threshold and sends the information to module 3, MCU controls modules 1, 3 and 4to coordinate the work of the protection device.

Description

technical field [0001] The invention relates to a service protection device in an optical transmission system, in particular to a device in which a service protection threshold in the optical transmission system can be dynamically adjusted. Background technique [0002] With the development of optical transmission technology, customers have put forward higher and higher requirements for the security and robustness of services carried in the optical transmission system. Optical transmission equipment that can realize service protection functions emerges as the times require, and gradually gets more and more applications. The types of service protection functions of this optical transmission device with service protection functions include channel protection, multiplex section protection, 1+1 protection, 1:1 protection, 1:N protection and so on. [0003] At present, the protection device in the optical transmission system has a relatively single function, and it is often impo...
