Abstract
  • Interconnection Networks have been used as a high performance communication fabric in parallel processor architectures. Parallel processors built using off-the-shelf components, called clusters, are becoming increasingly attractive because of their high performance to cost ratio over parallel computers. Many web servers and database servers make efficient use of clustering from cost, scalability and availability standpoints. The Design of high performance cluster networks with QoS guarantees is becoming increasingly important to support a variety of multimedia applications, many of which have real time constraints. Most commercial routers, which are based on the wormhole switching paradigm, can deliver high performance, but lack QoS provisioning. A new router architecture with support for QoS provisioning was introduced in [1]. In this project we present a detailed analysis of the hardware complexity of the router in [1] and propose some architectural modifications to reduce the hardware complexity of the router. We have also developed a simulator to compare and analyze the performance characteristics of the proposed router architecture.
