the capacity

As society and economic development, network technology is changing fast, there is an explosive growth trend in internet business in the world, meanwhile, the demand of communicate traffic is more high-level and diversity. Although this is a huge challenge for the capacity of communication network, the emergence of fiber communication technology brings discount wedding prom dresses vibrant opportunities. As fast optical network technology development, optical fiber communication gradually evolves into an important networking means from the simple transmission wedding dresses form china technology. Optical transmission network with huge capacity and cheap nike shoes good flexibility, based on wavelength division multiplexing (WDM), becomes the focus in current chi hair straightener optical communication field.By utilizing equipments like Optical Cross Connect (cheap polo shirts), WDM network could provide end-to-end light-paths to source-destination node pairs and re-use wavelength resources. On the other hand, a single node or link failure will cause severe service disruption in such network, since large amount of traffic is aggregated to less equipment owing to the use of WDM technology. Hence, network survivability has becoming a critical problem in network design. Meanwhile, dynamic characteristics of network traffic shows increasingly, it demands WDM should have the ablity of responding dynamic traffic quickly.
