Abstract

This paper studies generalized k-ary Data Vortex networks both with and without node buffering. The comparison study focuses on effects of buffering in 4-ary networks and in original binary networks. The results show that with buffers the 4-ary networks gain more performance benefit than that in the binary networks. This is due to significantly reduced traffic backpressure that is present in 4-ary networks in bufferless operations. Detailed comparisons between 4-ary and binary networks with two different buffering schemes are presented. The routing performance in throughput and latency are studied for different network and load conditions. For practical implementation, additional cost due to buffering should be justified for the desirable performance enhancement.
