An Efficient Signaling Protocol for Distributed-Controlled Optical Networks
分布式控制光网络的一种高效信令协议

An efficient signaling protocol, Tell-and-go, is proposed to perform fast lightpath provisioning for distributed-controlled optical wavelength-routed networks, in which switch reconfiguration can be performed in parallel at each node along the path. Simulation results indicate that the Tell-and-go signaling protocol achieves better network performance than the backward signaling protocol, in terms of lower blocking probability, shorter average lightpath setup time, in spite of slightly higher control bandwidth requirement.
