A METHOD ABOUT PROTECTING HIGH LAYER SERVICE IN THE MUTILAYER COMMUNICATION EQIPMENT

摘要

This invention relates a method about protecting high layer service in the multilayer communication equipment, including low layer processing module provides transmission channels for high layer. Transparence VP link gateway is set up for up and down node by high layer processing module, in order to make the service content processed by the said module avoiding influence. After detecting the fault of the said processing module, high layer processing module message the low layer processing module, then the low layer processing module set up side road after detecting the fault of the high layer processing module, then separating the failed high layer process module. According to this invention, more network channels are not necessary, the protect of cluster network is not limited; the present invention aims to protect ATM service in the case of that ATM layer invalidate in the node of multiple service provision platform and multiple service transmit platform. The present invention solves the influencing of service from the other node to the said node in the case of device maintenance.
