Method and system for providing a protection path for connection-oriented signals in a telecommunications network
First Claim
1. A system for providing a protection path for connection-oriented signals in a telecommunications network comprising a plurality of nodes, the system comprising:
- a source node operable to transmit traffic;
a destination node operable to receive traffic from the source node; and
a penultimate node operable to receive traffic from the source node, to transmit traffic directly to the destination node, to designate one of the nodes as a reflector and to generate a first segment of a protection path from the penultimate node through the reflector to the destination node.

Abstract
A system is provided for providing a protection path for connection-oriented signals in a telecommunications network comprising a plurality of nodes. The system includes a source node, a destination node and a penultimate node. The source node is operable to transmit traffic. The destination node is operable to receive traffic from the source node. The penultimate node is operable to receive traffic from the source node, to transmit traffic directly to the destination node, to designate one of the nodes as a reflector and to generate a first segment of a protection path from the penultimate node through the reflector to the destination node.

11. A node in a telecommunications network, comprising:
-
an ingress port operable to receive working traffic on a working path and protection traffic on a protection path;
a reflector identifier operable to identify the node as a reflector based on the received traffic;
a protection path generator operable to generate a protection path based on an identification of the node as a reflector;
a penultimate node identifier operable to identify the node as a penultimate node based on the received traffic and based on a determination that the node is operable to transmit working traffic directly to a destination node to which the node is coupled, the protection path generator further operable to generate a protection path based on the identification of the node as a penultimate node; and
an egress port operable to transmit traffic. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method for providing a protection path for connection-oriented signals in a telecommunications network comprising a plurality of nodes, the method comprising:
-
identifying a source node operable to transmit traffic;
identifying a destination node operable to receive traffic from the source node;
identifying a penultimate node operable to transmit traffic directly to the destination node;
designating one of the nodes as a reflector; and
generating a first segment of a protection path from the penultimate node through the reflector to the destination node. - View Dependent Claims (20, 21, 22, 23, 24, 25)
identifying the traffic received at the penultimate node as working traffic or protection traffic;
transmitting the working traffic received at the penultimate node directly from the penultimate node to the destination node;
identifying the traffic received at the reflector as working traffic or protection traffic; and
transmitting the protection traffic received at the reflector directly from the reflector to the destination node.

-
21. The method of claim 19, the source node comprising the reflector.
-
22. The method of claim 19, further comprising:
designating one of the nodes as a next reflector; and
generating a second segment of the protection path from a node upstream of the reflector through the next reflector to a node downstream of the reflector.
-
23. The method of claim 22, further comprising:
-
identifying the traffic received at the penultimate node as working traffic or protection traffic;
transmitting the working traffic received at the penultimate node directly from the penultimate node to the destination node;
identifying the traffic received at the reflector as working traffic or protection traffic;
transmitting the protection traffic received at the reflector directly from the reflector to the destination node;
identifying the traffic received at the next reflector as working traffic or protection traffic; and
transmitting the protection traffic received at the next reflector directly from the next reflector to the node downstream of the reflector.

-
24. The method of claim 22, the source node comprising the next reflector.
-
25. The method of claim 22, designating one of the nodes as a reflector comprising designating one of the nodes as a reflector based on Quality of Service for the traffic.
