Abstract
An auditing function detects and corrects reservation and routing topology map errors by monitoring the operation of an advanced bandwidth manager (ABM). A session/call admission controller (S/CAC) attached to a network manages loading with policy enforcement points (PEP's) when the network nears or exceeds its capacity. Ever-changing network topology information is monitored, modeled, and analyzed from remote listeners. A correct model of how traffic is being routed through various parts of the network is critical to admission control. The PEP's at the network edges provide short-term, application-aware controls on their own that are applied to the corresponding network ingress traffic. The S/CAC uses the path tables to calculate whether particular PEP's can admit more traffic, or should they shed sessions/calls to keep service up for the existing application traffic. Long-term controls are periodically downloaded as admission tables from the S/CAC to the PEP's.
