摘　　要：通用多协议标签交换技术(GMPLS)推动着电力通信光网络向智能化方向发展,同时,云计算、高清视频分发等新业务的发展使得点到多点的光多播在电力通信光网络中得到越来越多的应用。文章基于GMPSL信令协议RSVP-TE提出了一种新的光多播连接信令机制,它避免了原机制中可能的预留冲突问题,且能够提高网络中波长转换器的利用效率,从而提高了多播连接建立的成功概率。Generalized multiprotocol label switching （GMPLS） technology is leading power communication optical network to intelligent direction. Meanwhile, new businesses, such as cloud computing and high-definition video delivery, make the optical multicast technology more widely applied to power communication optical network. Based on GMPLS signaling protocol RSVP-TE, this paper proposes a new optical multicast signaling mechanism,which solves the issue of reservation confilicts in the previous signaling mechanism, and increases the probabilities of successfully establishing multicast connections by improve the usage efficiency of wavelength converter.
