Abstract

The layer 3 switch enables us to transmit IP datagrams using the cut-through technique. There are mainly two schemes of connection setup; one is the flow-driven case and another is the topology-driven one. In this paper, we analyze the cut-through rate, the datagram waiting time and the mis-ordered rate as performance measures of both cases and compare these performances. In the analysis, by using the interrupted Bernoulli process (IBP), we model the arrival process of the IP flow and the IP datagram from each source. Furthermore, we investigate the impacts of the arrival rate and the average IP flow length on performance
