Research on traffic engineering technology for WDM communication network

In WDM network, the load balance problem has received much attention in parallel and distributed applications because good solutions are critical to achieving speedups. This paper discusses traffic technology and load balancing in optical networks. In WDM network, enhancing the performance of an operational network, at both the traffic and the resource levels, are major objectives of traffic engineering. The goal of performance optimization of operational IP networks is accomplished by routing traffic in a way to utilize network resources efficiently and reliably. Traffic engineering has been used to imply a range of objectives, including load balancing, constraint-based routing, multi-path routing, fast re-routing, protection switching.
