摘　　要：利用虚拟网络来对真实的应用程序性能进行检测的技术通常指网络仿真技术,其能够有效评估程序性能,并预测网络变化所带来的影响。为了解决传统方法的低稳定性问题,研究将多尺度与虚拟网络映射方法相互结合为MIM-HE方法。该方法能够对网络拓扑展开合理地划分。结果表明,MIM-HE方法下第一组拓扑到第三组拓扑的负载不均衡指数分别为13.66,4.08,2.34,相较于MLMB与虚拟网络映射分别降低了39.88%与94.35%;远程通信开销指数也小于其余两种方法。这表示MIM-HE方法能够有效促进大规模网络拓扑进行快速映射。Network simulation is a technology that uses virtual network to detect the performance of real applications.It can effectively evaluate the performance of programs and predict the impact of network changes.In order to solve the problem of low stability of traditional methods,we study the combination of multi-scale and virtual network mapping methods into MIM-HE method.This method can divide the network topology reasonably.The results show that the load unbalance index from the first group of topology to the third group of topology under the MIM-HE method is 13.66,4.08 and 2.34 respectively,which is 39.88%and 94.35%lower than that of MLMB and virtual network mapping respectively.The telecommunication cost index is also smaller than the other two methods.This means that MIM-HE method can effectively promote the rapid mapping of large-scale network topology.
