SEGMENT ROUTING: PCE DRIVEN DYNAMIC SETUP OF FORWARDING ADJACENCIES AND EXPLICIT PATH

摘要

An apparatus and method for path creation element driven dynamic setup of forwarding adjacencies and explicit path. In one embodiment of the method, a node receives an instruction to create a tunnel between the node and another node. The node creates or initiates the creation of the tunnel in response to receiving the instruction, wherein the tunnel comprises a plurality of nodes in data communication between the node and the other node. The node maps a first identifier (ID) to information relating to the tunnel. The node advertises the first ID to other nodes in a network of nodes.

1. A method comprising:
a node receiving an instruction to create a tunnel between the node and another node via a plurality of nodes in data communication between the node and the other node; in response to receiving the instruction, the node mapping a first segment identifier (ID) to a label distribution protocol (LDP) label relating to the tunnel; the node advertising the first segment ID to other nodes in a network of nodes.
