Abstract
The performance of multiprocessor systems is greatly dependent on interconnections and their fault tolerance ability. Handling faults becomes very important to ensure steady and robust working. This paper introduces, a new CGIN with at least 3 disjoint paths. It uses an alternate source at the initial stage, due to which at least 3 disjoint paths can be ensured. The network provides multiple paths between any source and destination pair. The alternate source guarantees delivery of packets to the intended destination, even if two switches or links fail. The alternate source proves quite helpful in case of any fault at initial stage, or the source is busy. In such cases, the packets can be retransmitted through the alternate source to avoid delayed delivery or starvation, which was not being used in original CGIN. This network also provides the dynamic re-routing to tolerate faults. The paper further presents two very simple routing strategies – first for routing in fault free environment and second for routing in faulty environment.
