Patent ID: 7489866

Claim:
A method for generating multiple-homing diversification routes in a transport network, between an ingress client node and an egress client node, without transmitting proprietary information out of the transport network, comprising: establishing a first path through the transport network between the ingress client node and the egress client node through a first ingress network element within the transport network; initiating creation of a diversification path between the ingress client node and the egress client node through the transport network by transmitting a connection create request to a second ingress network element only within the transport network by the ingress client node, wherein the connection create request includes information identifying a first connection with the first ingress network element; transmitting the information identifying the first connection from the second ingress network element to the first ingress network element, the transmitting the information occurring only within the transport network; transmitting by the first ingress network element to the second ingress network element information associated with the first path only through the transport network; and establishing the diversification path through the transport network responsive to the information associated with the first path.
