摘要

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、连接阻塞概率和连接建立时间等方面具有更好的性能.

Abstract

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.
