Performance Analysis of 100 Mbps PACE Technology Ethernet Networks

100BASE-T has enhanced the performance of Ethernet networks from 10 to 100 Mbps. However, an Ethernet network under high offered load can produce unpredictable and excessive packet delays due to the capture effect introduced by the Binary Exponential Backoff (BEB) algorithm. A solution that efficiently overcomes this problem is the PACE algorithm. This paper presents a performance analysis of several schemes of an algorithm based on PACE technology. We developed a mathematical model of the system and we used the Equilibrium Point Analysis (EPA) technique in order to analyze the above model. It is shown that the proposed schemes improve the performance of the network both in terms of throughput and average packet delay.
