基于网络编码的光组播树优化RWA研究

Optimized RWA based on network coding for optical multicast trees

为了降低网络负载均衡率与平均阻塞率,提出了基于分层图的具有网络编码能力的共享光组播树算法。通过对该算法的仿真表明,具有网络编码能力的共享光组播树在使用的光路数、平均阻塞率以及网络负载均衡率上要优于共享树。最后作了总结并指出将来的研究方向。

This paper proposed an algorithm of shared optical multicast tree with network coding based on the layered graph. The algorithm could release the average blocking probability and network load balancing probability. The simulation results show that the shared optical muhicast tree with network coding in the use of the optical approach,the average blocking probability and network load balancing ratio is superior to shared tree. Finally, the paper summarized and also pointed out some future works.
