摘要 分组增强型光传送网(P-OTN)兼具分组传送网(PTN)和光传送网(OTN)的优点,是下一代光传送网的理想选择。三次握手信令协议(3WHS)是业界最先进的分布式连接建立机制,通过3次消息过程实现网络中连接的快速建立;同时,通过额外预留网络资源,有效解决"后向阻塞"问题。在P-OTN网络中,通过采用3WHS信令协议技术,结合路径计算单元(PCE)技术,能够实现网络资源的快速智能调度。 Packet-enhanced Optical Transport Network(P-OTN) possesses the merits of Packet Transport Network(PTN) and Optical Transport Network(OTN),which is the ideal technology of next generation optical transport network.Three-Way-HandShake(3WHS) signaling protocol is the most advanced distributed connection setup mechanism,which uses three steps signaling procedure for fast connection setup.By reserving extra resources,it can effectively solves "backward blocking".By using 3WHS signaling protocol working in concert with a Path Computation Element(PCE),Packet-enhanced Optical Transport Network can realize fast and automatic resources controlling.
