RTTM:New interconnection network structure with hierarchical twist Torus
Jungang Han · Journal of Computer Applications · 2009
Because of low utilization rate and uneven load value of rectangular Torus,this paper presented a new hierarchical twist Torus structure named Rectangular Twisted Torus Meshes (RTTM). At the lowest level of RTTM network,the level-1 sub-network,also called a basic module,consisted of a mesh connection of 2m×2m nodes. Successively higher level networks were built by recursively interconnecting a×2a next lower level sub-networks in the form of a rectangular twisted Torus. RTTM network has smaller diameter and average distance,which implies a minimization of the network communication delays. The simulation results by OPNET,consistent with theoretical analysis,show that the network is of high utilization rate,small end-to-end delay and larger capacity.
