WDM光网络规划优化方法

Recently, with the development of networking technologies and new services of Internet, there is an explosive growth trend of Internet traffic, which needs tremendous network bandwidth. The advances in optical fiber transmission technology over the past years have kept pace with the demand for increased bandwidth. In particular the introduction of the WDM technology enables Telecom Operators to upgrade the capacity of their networks by an order of magnitude. Some new designing and planning problems of optical networks are brought up with the use of new technologies. In this paper, we discussed the planning and optimizing methods of the core WDM transport networks and the network survivability in network planning.
