Performance Evaluation of a User Network Interface for ATM Networks

In this paper the functionality requirements of a user-network interface for bandwidth allocation are discussed. Such requirements include the capability to provide end users with a variety of non-deteriorating connection types. In addition effective policy enforcement and traffic shaping mechanisms are required to facilitate network management and the efficient utilization of network resources. Based on these requirements, a user-network interface model is proposed, and its performance is studied. Its intrinsic properties are revealed for two cases, a Poisson source and a bursty source.
