Abstract:
We proposed the solutions to enhance the performance of deflection router with minimal buffering. These include the modification of the port allocation algorithm and architecture of the baseline deflection router. It enabled to bring a new architecture, the buffer inject stage is placed at the output, instead of input of the port allocation stage. The new arrived algorithm deployed the prioritized instead of randomized selection while choosing deflected flit for in-router buffering. We did experimentation which shown that the proposed modifications yield a reasonable changes in network saturation throughput under uniform traffic pattern.
