One possible solution may leadto the design of integrated router and cache controllers. In my recentwork, I have investigated methods to enhance known wormhole routing algorithmsto handle faults, deadlock issues in multicast communication, and design ofnew wormhole routing algorithms. I am applying my results on fault-tolerantand multicast communication to current router designs such as the multichiprouters implemented in Cray T3D(TM) to study the design of next generationrouters and switch fabrics for high-speed local area networks.<p><h2>Representative Publications</h2> R.V.
