A Model for Self-Similar Ethernet LAN Traffic: Design, Implementation, and Performance Implications
Y. Chen, Carey L. Williamson · 1995
This paper presents a synthetic workload model that is capable of modeling self-similar Ethernet traffic. The design of the model is presented, along with a brief description of its implementation in SimKit, a C ++ -based simulation interface to support efficient parallel simulation on Shared Memory TimeWarp (SMTW). Preliminary simulation results are presented comparing the cell loss and cell delay performance in a simulated ATM network, both with and without the presence of self-similar traffic. Results suggest that simple Poisson traffic models, as opposed to self-similar traffic models, may underestimate ATM cell loss by several orders of magnitude, depending on the network utilization. Selfsimilar traffic models thus provide a valuable tool for "worst-case" stress testing of ATM networks. 1 INTRODUCTION Recent research in network traffic measurement has established the "self-similar" nature of aggregate Ethernet local area network (LAN) traffic (Leland et al. 1994), as well as ...
