On Bandwidth Capabilites of Multiprocessor Interconnection Networks

In this paper the general characteristics and bandwidth capabilities of Multiprocessor Interconnection Networks have been analyzed. We have examined some popular FT(Four Tree)[8],MFT(Modified Four Tree)[2],THN(Theta Network)[13],NFT(New Four Tree)[4], IFT(Improved Four Tree)[5], IASN(Irregular Augmented Shuffle Network)[14] and IIASN(Improved Irregular Augmented Shuffle Netwrok) [3] networks which are irregular in nature[11]. The structural characteristics comparison of these networks is presented in terms of number of switches, links and stages etc. The bandwidth [15] and probability of acceptance of all the networks evaluated by using probabilistic approach [6] and their simulation results are compared.
