摘　　要：为了解决RSVP-TE信令机制在建立光多播连接时的波长预留冲突问题,提出了一种基于两次信令握手的新的光多播信令机制,给出了该信令机制的波长和路由分配过程。通过仿真实验,结果表明:在相同的网络负载下,新的光多播信令机制可以有效减少网络中波长转换器的使用数量,降低光多播连接的网络阻塞率。In order to resolve the wavelength reservation conflict problem of RSVP-TE signaling mechanism when it establishes the optical multicast connection, a new optical multicast signaling mechanism based on two signaling handclasp is put forward, and the wavelength and route allocation process of the new signaling mechanism is provided. Through the simulation experiment, the results demonstrate that under the same net-work load, the new optical multicast signaling mechanism can effectively reduce the usage number of wave- length conversion device in the network, and decrease the network block ratio of the optical multicast connection.
