Abstract :
Direct networks are the counterparts of indirect networks like multistage interconnect networks which rooted in the telecommunication and parallel computing. Direct networks are getting more and more promising in latest data center networking research. Torus is one of the most popular direct networks and it is a common practice in supercomputers and some core routers. In this paper we proposed a novel hybrid architecture which is formed by adding extra channels to a classic torus network. The channels are added in a fashion that has been proved to be asymptotical minimal for load-balancing, besides, we devised the corresponding load-balancing routing scheme for this hybrid architecture. Static network characteristics is analyzed and compared with other direct networks. Simulation results are provided to show that these express paths improved the network performance in concert to the theoretical analysis.
