摘要

错连就是在发生保护倒换时

一条业务被传送到另外的节点

而不是预定的节点并且没有纠正动作的情形.它是由波长重用和共享保护引起的.采用波长重用和共享保护的波分复用（WDM）环网在多点故障或节点失效时将产生错连.文章将就如何检测和阻止错连

提出一些见解.

Abstract

When there are protect switches in the optical network

misconnection may happen if a service channel is ended at a wrong destination node rather than the preplaned one and the network management system don’t correct it. Misconnection results from share protection and wavelength reuse. Lightpathes of WDM ring using share protect and wavelength reuse will be easy to misconnect when multi-fiber-fault or node-fault happen. In this paper we propose a solution to check and prevent the misconnection.
