Abstract

Способ перевода трафика, передаваемого между первым узлом и вторым узлом, для передачи по защитным линиям связи, способ содержит этапы, на которых обнаруживают сбой в первой оптической линии связи на втором узле; если энергия, принятая по оптической линии приема на втором узле, не превышает заданный порог, переводят передачу и прием трафика на втором узле на соответствующие защитные линии связи; обнаруживают сбой в первой оптической линии связи на первом узле; если энергия, принятая по первой оптической линии связи на первом узле, не превышает заданный порог, переводят передачу и прием трафика на первом узле на соответствующие линии связи.Отчет о международном поиске был опубликован 2001.09.27.
