Patent ID: 8385194

Claim:
A system for providing quality of service (QOS) in a network, comprising: at least one remote listener to gather interior gateway protocol (IGP) reports about how traffic is being routed over the whole network; an advanced bandwidth manager (ABM) to manage loading when an attached network nears or exceeds its capacity due to component failures, incremental growth, and other changes in the network, the advanced bandwidth manager comprising a processor for abstracting the routing information gathered by remote listeners into point-to-point admission control tables and pushing the admission control tables to at least one edge of the network; and at least one policy enforcement point (PEP) attached to the at least one edge of the network and configured to autonomously control admission of network ingress traffic at said at least one PEP based on the admission control tables wherein the admission control tables are stored locally on the at least one PEP and used by the at least one PEP to implement long-term traffic admission controls that differentiate between traffic classes, and the admission control tables are automatically updated by the ABM and downloaded by the at least one PEP in response to a change in packet-switched network topology or bandwidth reservation capacity due to a network failure.
