Link Conflict in Multistage Interconnection Networks
Shobha Arya, Nipur Singh · International Journal of Engineering Research and Applications · 2017
Multistage interconnection networks (MINs) are high performance indispensable networks with low cost for broadband switching technology and multiprocessor systems.Crosstalk is a critical issue in MINs.The undesired coupling of two or more wavelengths is reason behind Crosstalk and Link Conflicts and Switch Conflicts can cause it.In Electrical or traditional MINs, link conflict is the only reason behind crosstalk but in optical MINs, both conflicts (switch conflicts and link conflicts) occurs in crosstalk.In traditional MIN or electrical MIN, the link conflict problem can also be arises because of congestion.In this paper, we are going to discuss about link conflict problem in electrical MIN.In this paper, we proposed a new link conflict detection method named Link Window Method (LWM) to detect link conflicts in omega MIN.Congestion can also be identified in switches with the help of proposed algorithm.
