The present invention relates to a protection switching for use in a communication network, and more particularly, to a method and a system for protection switching provision by a distributed or extended protection group in a communication network. In one embodiment, this can be accomplished by defining a traffic bit (t-bit) on all the communication devices in the network, assigning at least one communication device as master node and other devices as slave node, determining a fault if continuity check message is not received in a predetermined time period between the master node and the traffic source, carrying of status information, reliably, between communication devices using existing protection or restoration methods, broadcasting by setting the bit ‘t’=1 (or ‘t’=0) by the master node to all other slave nodes thereby notifying about the fault (or clearance of fault) towards traffic source and receiving the traffic from the traffic source by the other available slave nodes when master node's link towards traffic source fails.
A protection switching method in a communication network, the communication network including a plurality of communication devices connected logically to receive traffic from at least one traffic source, the method comprising:
A protection switching system in a communication network, the system comprising:
