WSURF Case 937
Fault Tolerant, Scalable High-Performance Router Architecture
Summary
WSU researchers have created a novel architecture for improving the performance of a router. Using interleaved multistage switching fabrics, this architecture creates a faster router which is scalable and has greater fault tolerance. This technology is applicable to delta-class networks such as: baseline, reverse baseline, Omega, Banyan, and N-cube.
Routers can be evaluated on the basis of scalability, reliability, and cost. In this design, a self-routing method was used to solve for high routing complexity, making it scalable for next generation networks. This invention provides higher performance and reliability than normal delta class self-routing multistage interconnection networks.
Applications & Advantages
- Faster – speedups (over single panel fabric) of 3.4 and 2.25 under uniform and hot-spot traffic patterns at maximum load
- Scalable – for next generation networks
- Improved fault tolerance – better performance and reliability than normal delta class self-routing multistage interconnection networks
