摘　　要：IETF组织给出了多粒度光网络中的标签粒度定义,但是没有对相应的信令实现流程进行规范.本文提出了一种用于多粒度光网络中的业务驱动模式下基于通用多协议标签交换(GMPLS)的动态信令控制机制.通过对信令流程进行有限状态机的分析可以看出,本文提出的多粒度信令建立流程能够完成多粒度光通道的建立、释放与调制操作,可以很好地满足不同粒度标签请求到达的情形.The multi-granularity labels has been defined by Internet engineering task force (IETF), but the corresponding signaling process has not been standardized up to now. A new generalized multi-protocol label switching based signaling mechanism, which could be used for multi-granularity optical networks to create, release and modify its optical paths under the service-driven model, was proposed. With the help of communication finite state machine (CFSM) to analyze the signaling mechanism, we conclude that the signaling mechanism proposed could be satisfied in the dynamic requirement of different granularity optical paths.
