摘要 为了节约网络成本和提高网络性能,将RSVP协议和OSPF协议进行扩展,提出了一个支持业务梳理的智能光网络组播协议,给出了消息类型,信令流程及状态机模型,并通过仿真验证协议性能.仿真表明,业务梳理可以一定程度降低组播业务阻塞率,但业务建立时延却大于不存在梳理的情况.梳理的存在使业务建立时延随着业务量的增大有一个由小变大再减小的过程. By extending RSVP and OSPF, a multicast protocol supporting traffic grooming in intelligent optical network is provided and the message type, signaling flow and state machine model are given. Simulations are used to verify the protocol performance. It shows that traffic grooming can decrease the blocking probability to some degree,but the traffic setup delay is longer than that without grooming. With the increase of traffic load,the setup dealy under grooming condition has a course of from short to long and again to short.
