摘要
讨论了基于GMPLS的约束路由机制和约束路由算法,提出了一种适用于智能光网络的CSPF算法。该算法通过考虑SRLG约束和负载平衡因子,能够支持业务的保护与恢复,并在一定程度上均衡业务流量,提高全网资源利用率,从而降低业务阻塞率,通过多次仿真实验验证,该算法是可用的和有效的。
GMPLS is the core technology in the next generation optical networks. The purpose of the paper is to present an algorithm to solve the problem of TE in GMPLS networks. And the heuristic algorithm is the constraint-based shortest path first algorithm with more than one constraint. It can balance the load of some links and improve the utility of network resources, while meeting the QoS requests of the connection to some extent, such as bandwidth and delayo Furthermore, the simulation is made to verify the validity and practicability of the algorithm.
