Virtual channel and path allocation in ATM networks

An asynchronous transfer mode (ATM) network provides a connection-oriented service by establishing a virtual channel (VC) between a source and destination node. Virtual paths (VPs) facilitate virtual channel allocation by partitioning network resources along pre-calculated routes. This paper proposes a framework for the allocation of VCs and VPs in an ATM network. Our approach is based on approximating the required resources of calls and then formulating a multirate loss network model for an ATM network. We propose a decentralized algorithm for adaptively adjusting offered loads to network routes and VP bandwidth assignments
