Patent ID: 8547981

Claim:
In a multi-node, connection oriented packet data network, a method of building a label switched path on demand between a transmitting computer at a first node and a receiving computer at a second node comprising: automatically exposing a single, optimized path right-of-way, on demand from the first node to the second node in response to a connection request by the transmitting computer, where the right-of-way traverses at least one intermediate node, and where sufficient links exist to allow multiple possible right-of-ways; limiting said right-of-way to links with available bandwidth introducing a time delay at one or more nodes as part of exposing the path right-of-way between the first node and the second node, where the amount of delay had been previously stored in a memory; automatically building a label switched path along said right-of-way from the second node to the first node in response to the acceptance of the connection request by the receiving computer; and transmitting of data along said label switched path.
