Paper Abstract

Bandwidth demand in Internet is growing at a very fast rate. While links can provide the requested bandwidth, the situation is much more critical for routers. The design of high-speed switching fabric is a crucial part in current routers and switches. This paper presents a scalable and high speed switching fabrics for Internet routers— —torus network, which was mainly used in high performance computers before. Using wornihole routing and virtual channel in torus network can achieve a high-speed and scalable switching fabric for Internet router. In this paper, the performance of 4 X 3 X 2 3D torus network was analyzed as a core switching fabric for Internet routers. A novel dynamic and distribute routing algorithm is employed at switching system. We achieved an analysis model in OPNET simulation tools. Throughput and latency characteristic can be analyzed through this model. Simulation results show that maximal throughput is close to 100% under uniform traffic with low latency. It was found that using this architecture can reach Tera-bit capacity switching fabric and can be expanded from 36OGbit/s to 1.6 Tbit/s without increasing the link speed between nodes. At last, this paper presents some exciting directions in which the work can be extended.
