摘要

传统的基于环的网络已经与SONET/SDH技术一起部署,以提供传输网络的生存能力。检测到故障后50ms内恢复业务。随着具有GMPLS控制平面的光传输网络的出现,必须研究有效的弹性机制,以提供与SONET/SDH网络相当的恢复时间。本文描述了一种支持专用区段保护(OMS-DPRing)方案的可重构光加丢复用器(ROADM)设计。将这些新的roadm与GMPLS链路管理协议(LMP)的拟议扩展相结合,将允许实现与SONET/SDH架构授予的恢复时间相当的恢复时间。

ROADM design for OMS-DPRing protection in GMPLS-based optical networks
Legacy ring based networks have been deployed in conjunction with SONET/SDH technology to provide survivability to transport networks. Service recovery within 50 ms after fault detection can be achieved. With the advent of optical transport networks provided with GMPLS control plane, efficient resilience mechanism have to be investigated to provide recovery times equivalent to those granted by SONET/SDH networks. In this paper a reconfigurable optical add and drop multiplexer (ROADM) design to support dedicated section protection (OMS-DPRing) scheme is described. Using these new ROADMs in conjunction with proposed extensions to GMPLS link management protocol (LMP) will allow achieve recovery times equivalent to those granted by SONET/SDH architectures.
