Several existing studies have revealed that pipelined circuit switching (or PCS for short) can provide superior performance characteristics over wormhole switching. This paper proposes a new analytical model for PCS in high-radix high-dimensional k-ary n-cubes augmented with virtual channel support. The model uses Random Walk Theory to analyse the backtracking actions of the message header during the path set-up phase, and M/G/1 queueing systems to compute the mean waiting time that a message experiences at a source node before entering the network. Results from simulation experiments confirm that the proposed model exhibits a good degree of accuracy for various network sizes and under different operating conditions.
