METHOD AND SYSTEM FOR SOLVING COMMUNICATION FAILURE AND TRAFFIC LOSS IN SERVICE PROTECTION NETWORKS

摘要

A method for solving communication failure includes transmitting user traffic over an automatic protection switching (“APS”) connection between a near network node and a far network node, determining that a protect path on the APS connection has failed, sending a message to the far network node that the protect path has failed, and switching user traffic to the working path at the near network node.
