Abstract
Cut-through switching is advantageous in that it can reduce the transmission delay compared with the conventional message or packet switching. In this paper, when the channel is noisy, we investigate various properties of M/D/1 quasi-cut-through switching including actual traffic intensity and overall network delay. In the analysis of delay resulting from retransmission of erroneous packets, we have included the average transmission time of negative acknowledgment signal and queueing time for the retransmitted packet so that the overall network delay can be obtained accurately. In addition, we have obtained distributions of the number of nodes to be traversed and the number of nodes through which packets pass by cut. According to the analysis results, the performance of cut-through switching is superior to that of conventional packet switching in most practical ranges of parameter values.
