Abstract
A method of determining whether to set up a delay-sensitive communication session over an internet protocol (IP) based network includes sharing link state information among the network nodes of the link state protocol controlled network, receiving an IP packet that conveys a request to set up a delay-sensitive communication session over the network; determining, based on the shared link state information, a shortest path through the link state protocol controlled network for the requested delay-sensitive communication session and whether the shortest path is deemed suitable for the delay-sensitive communication session, and setting up the delay-sensitive communication session over the shortest path only when the shortest path is deemed suitable for the delay-sensitive communication session.
