For the low utilization rate and uneven load value on the Rectangular Torus,this paper presents a new hierarchical twist Torus structure——RTTM.It is a N-level network.The Level-1 sub-network,also called a Basic Module,consists of a mesh connection of 2m×2m nodes.Successively higher level networks are built by recursively interconnecting a×2a nodes in the form of a Rectangular Twisted Torus.With the OPNET modeling environment,this paper completed seperately two levels modeling of the RTTM network structure.The first level is made up of 4×4 nodes of Mesh structure,and the second level is made up of 4×8 nodes of Torus structure.The simulation results show that the network has high utilization rate,smaller end-to-end delay and larger throughput by OPNET.
