Bypassing omega network for high speed packet switching

A highly regular switching network consisting of several switching stages for output buffering is proposed. Each switching element performs 3×3 switching and has a tail-spared buffer for each input port. According to the performance evaluation of the proposed switching network based on computer simulation, a packet loss ratio of 10^-8 was obtained for a 1024×1024 switching network consisting of 15 stages with the Bernoulli traffic source when the size of tail-spared buffer is 8 and the input traffic load is 0.9
