一种用于波长路由光网络的分布式快速波长预留协议

波长预留协议用于在光通道建立过程中预留和配置波长.目前已有的波长预留协议都把协议设计的目标定为降低网络阻塞率,没有一种协议设计把目标定为缩短光通道的建立时间和简化协议处理过程.然而更短的建立时间和更小的协议复杂度对于未来极其动态的光网络却是非常重要的.提出了一种新颖的用于波长路由光网络的分布式快速波长预留协议-目的端预留协议,它在保证网络阻塞率可以接受的前提下,不仅可以降低连接建立时间,还可以减少控制节点处理器需要处理的信令消息数量.仿真结果证明了这一点.

A distributed fast wavelength reservation protocol in wavelength-routed networks

The distributed wavelength reservation protocols are used for wavelength reservation and configuration during the connection setup process.Such protocols proposed so far in the literature all aim to achieve better blocking performance.But no protocol based on local information has been developed to get a shorter setup time which is very important in the most dynamic networks in the future.A novel distributed wavelength reservation protocol for wavelength-routed networks,named destination reservation protocol(DRP),is proposed.The connection setup delay is shortened and the messages needed to be processed are reduced.Simulation results reveal that DRP outperforms the other protocols in the literature.
