Reliability performance of shuffle exchange omega network

Multistage Interconnection Networks (MINs) are design to provide an effective communication in switching. In optical MIN, optical signal are routed through the connecting path by electronically controlled switching element using directional coupler. Shuffle-exchange networks (SENs) have been widely considered as practical interconnection systems due to their size of it switching elements (SEs) and uncomplicated configuration. In this paper, the relationship between reliability performance and number of network size are compared in shuffle exchange network (SEN), SEN with minus one stages (SEN-) and SEN with additional stage (SEN+). There are three parameters used to measure the reliability performance on these networks which is terminal reliability, broadcast reliability and network reliability. From the results the proposed SEN- have a better reliability performance compared to SEN and SEN+.
