DWDM光分组交换节点中的波长信道分离和缓冲器分段路由

提出了业务有高、低两种优先权要求时，DWDM光分组交换节点波长信道动态分离路由的方法，建立了波长信道分离和缓冲器分段存储两种方法的解析模型.两种方法的优化结果表明，当节点具有全波长转换且缓冲器深度较小时，相比于缓冲器分段法，信道分离法的高优数据丢包率（PLR）有较好的改善.

Wavelength-Separation and Buffer-Sharing Routing in DWDM Optical Packet Switching Nodes

We propose a new routing method called wavelength-separating method in DWDM optical packet switching nodes for two-class priority traffics.Analytical models of the method and a buffer-sharing method with special contention control are derived.The optimized results of the two methods show that the wavelength-separating method achieves a better improvement of the packet loss rate(PLR) than the buffer-sharing method in the case of full wavelength conversion and small output buffer length.
