The switching method determines the way messages visit intermediate routers, and has a great impact on network performance. This paper conducts an extensive comparative performance analysis, by means of analytical modelling, of three well-known switching methods proposed for multicomputer networks, namely wormhole switching, circuit switching, and pipelined circuit switching. The results reveal that wormhole switching is the most efficient when messages are short. Pipelined circuit switching can perform better than circuit switching and provides superior performance over wormhole switching when messages are relatively long.
