Abstract
In this paper, 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. The
performance parameters studied are Normalized Throughput
and Normalized Delay. Simulation study of the switch is also
performed to validate the model proposed.
