摘要
交换超立方网络作为超立方网络的一个变种,具有良好的递归性和理想的网络参数。根据交换超立方网络的相关性质研究了E-2DMesh网络和超立方网络的嵌入问题,并得出如下结论:(1)当max(s,t)<7时,不存在dilation=1的EM(2m,2n)到EH(s,t)的嵌入映射(m+n≤s+t+1)。(2)EM(2s,2t)可以expansion=2,dilation=4,load=1嵌入EH(s,t)。(3)当min(s,t)>1时,不存在dilation=1的Qn到EH(s,t)的嵌入映射(n=s+t)。(4)Qn可以ex-pansion=2,dilation=3,congestion=1,load=1嵌入EH(s,t)(n=s+t)。上述结论进一步说明了交换超立方网络具有良好的扩容性。
As a new variant of hypercube,the exchanged hypercube has nice recursiveness and preferable network parameters.Based on the relevant properties of exchanged hypercube,this paper studied the problems of embedding E-2DMesh networks and hypercube networks into exchanged hypercube.The following conclusions are obtained:(1) for max(s,t)7,there is no mapping embedding for EM(2m,2n) into EH(s,t)(m+n≤s+t+1) with dilation=1.(2) EM(2s,2t) can be embedded into EH(s,t) with expansion=2,dilation=4,load=1.(3) for min(s,t)1,there is no mapping embedding for Qn into EH(s,t)(n=s+t) with dilation=1.(4) Qn can be embedded into EH(s,t) with expansion=2,dilation=3,congestion=1,load=1(n=s+t).The results show that exchanged hypercube has nice versatility.
