| description | At present the network management system of different types of equipment are relatively independent.The problem about how to quickly recover network failure towards inter-domain optical networks is required to be solved in terms of network operation and maintenance.Some fault location schemes within inter-domain optical networks were studied.When any inter-domain fault occurs, firstly, some technologies about automatic link discovery protocol and pilot tone technology of optical modules were applied to get complete optical link information and data.Then, real-time performance monitoring technology and root cause analysis function were used to find the root alarm towards specified network fault.Ultimately the management domain of optical transport networks has been extended by using those methods above on basis of developed prototype system of transmission network operation quality analysis, which may produce an end-to-end open and unified optical transport network management system including the remote client side. |
