Abstract
This paper describes a system for dynamic bandwidth management of Virtual Path Connections in ATM networks. A two level hierarchical approach is taken consisting of network planning functions which take place on a longer time scale than the bandwidth distribution functions which attempt to track the usage of the VPCs in terms of the switched VCCs admitted onto them. The paper concentrates on approaches for the latter of these sets of functions and places them in the context of a larger system for network survivability and availability as studied by the ACTS REFORM project.
