In this paper, the authors explain about the architecture of a multi-plane Parallel Deflection-Routed Circular Banyan (PDCB) network based switching fabric is introduced. The PDCB network has a cyclic, regular, self-routing, simple architecture and fairly good performance. Its Performance is improved due to reduction in blocking by two-dimensional path-multiplicity of the proposed architecture. It consists of 4X4 Switching Elements. The proposed switch is shown to be fault-tolerant. A simple analytical model based on Markov chain to evaluate the performance of proposed switch under uniform traffic condition has also been presented in this paper.
