Fault Tolerant Routing in Irregular Modified Shuffle Network

Dr. Harsh Sadawarti, Nirlaip Kaur, Kanwarpreet Kaur

Interconnection networks (IN) play very important role in various parallel processing applications. The connectivity pattern used in interconnection networks greatly determines the performance of the system. Multistage Interconnection Network is also an IN. The interconnection pattern used also determines the fault tolerance of the network. This paper introduces a new irregular fault tolerant multistage interconnection network named Irregular Modified Shuffle Network (IMSN). IMSN is analyzed in terms of fault tolerance and it has been observed that IMSN provides more alternate paths than existing networks such as Improved Four Tree Network (IFTN), Modified Alpha Network (MALN) and New Irregular Augmented Shuffle Network (NIASN).
