Simulation on Layered Graph-based Dynamic RWA Agorithm

RWA problem is an important issue for optical network. With the reduction of RWA optimized algorithm solution,the computational efficiency of the algorithm is improved at the expense of optimized performance. How to keep both optimized efficiency and time efficiency is the key point for the design of RWA algorithm in the optical network. This paper tells of the RWA problem in dynamic optical network. And the dynamic RWA algorithm based on layered graph is simulated,the simulation result proves that the algorithm could significantly reduce the network congestion,and it is fairly good in stability and high in utilization rate of resources.
