Reliability and Performance Analysis of New Fault Tolerant Irregular Network

A lot of work and analysis has been done on regular fault-tolerant MINs but irregular MINS have the inherent concept of favorite memory module offering lower latency. The multipath nature of these networks provides a non-blocking operation. This work introduces a new network, named as MFT-2 network, which contributes fault-tolerance by providing dynamic full-access capability in the presence of faults. MFT-2 network is improvement on irregular Four Tree network (FT). In case of any fault the system is reconfigured which operates in a degraded mode owing to the increased latency. But this approach minimizes the overheads of providing fault-tolerance, both in terms of cost and performance, during normal operation of the system. Irregular nature of these networks has reduced latency, improved dynamic fault-tolerant routing, high reliability and performance. The probabilistic approach is used to analyze the MINs based on independent request assumptions.
