Performance evaluation of reduced bandwidth multistage interconnection networks
D.T. Harper, J. Robert Jump · 1987
This paper presents and evaluates a class of buffered interconnection networks which provide performance and cost levels intermediate to a bus and a delta network. These networks, referred to as hybrid networks, are formed by beginning with a delta network and substituting buses for the final stages of the network. The choice of the number of stages replaced determines the bandwidth of the network. The reduction of network bandwidth is accompanied by a corresponding reduction in network cost. Hybrid networks provide the system architect with a cost-effective solution to design problems in which the required interconnection bandwidth is greater than that of a bus but less than that of a full delta network.
