CLEP——一种新的全光网络光路建立协议

CLEP-A New Lightpath Establishment Protocol in All Optical Networks

本文提出了一种波长交换光网络中混合模式的光路建立协议CLEP ,该协议充分利用现有基于正向预留的CR LDP协议和基于反向预留的RSVP TE协议各自的特点 ,通过使用混合模式的光路建立机制 ,使得信令协议在控制消息负载、实现复杂度。

We present a new lightpath establishment protocol CLEP (Compound Lightpath Establishment Protocol) for wavelength routed all optical networks. By using a compound lightpath establishment mechanism, as apposed to simple forward reservation by CR-LDP and backward reservation by RSVP-TE, CLEP outperforms both of them significantly in terms of connection blocking probability, lightpath setup delay, computational complexity and control message overhead.
