ABSTRACT:
A frame relay (FR) protection method generates an OAM frame to other nodes upon detecting a defect on a SONET ring. The protection frame comprises a type of failure and a location of failure. A node that detected the defect transmits the protection frame to other nodes about the location of the failure and the type failure. Protection tables are provided for switching a working fiber link to a protection fiber link. A protection switching provides a method re-establish FR traffic in spite of a detected failure on a SONET ring.
