讨论了基于GMPLS的约束路由机制和约束路由算法,提出了一种新的用于智能光网络的CSPF算法.该算法通过考虑业务优先级和负载平衡,能够满足业务的一般QoS需求,同时可以均衡业务流量,在一定程度上平衡网络负载,降低业务的阻塞率.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 this 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. Furthermore, the simulation is made to verify the validity and practicability of the algorithm.
