The effects of LAN-like input traffic on a switch access node

This paper addresses the modeling and analysis of a switching network access node. This is an area of importance due to forthcoming high-speed ATM backbone networks and the need to transmit data for current and future network applications. The nature of these applications must be considered when designing an access node to a switching network. A traffic arrival process for the network and characteristics of the access node are combined into an access node performance model. This model is implemented using Deterministic and Stochastic Petri Nets (DSPNs) which provides transitions with zero and deterministic firing times, as well as, exponentially distributed firing times, thus allowing the slotted behavior of the ATM interface to be captured in the model.
