Design and Reliability Modeling of FTGM

Abstract

The gamma interconnection network is a reliable network that provides redundancy in its basic topology but fault tolerance is still an issue to be addressed. Although the usage of MUX and DEMUX lessens the issue in gamma MIN's unique path behavior when the tag value is zero, it is still necessary to investigate the ideal size of MUX and DEMUX which may be used with gamma MIN in order to give the highest level of reliability. In order to make an overall generalization about all MINs, it is crucial to determine whether the findings achieved for the SEN MIN apply to other MINs that use switching elements of varying sizes. This chapter evaluates and presents the impact of larger MUX and DEMUX sizes on gamma MIN. The results of the evaluations show that the 4x1 MUX and 1×4 DEMUX provide the maximum level of dependability and that increasing the size of the MUX and DEMUX lowers the reliability to cost ratio.
