虚拟化与数字仿真融合的网络仿真任务划分

为提升网络仿真性能，面向虚拟化与数字仿真融合的网络仿真体系架构，研究相应的网络仿真任务划分方法。综合考虑虚拟化与数字仿真各自优势，将网络拓扑分为虚拟化拓扑区域与数字仿真拓扑区域，结合给定物理资源，以负载均衡与远程通信量最小化为目标，对两种区域进行融合划分。实验表明，通过该方法进行网络仿真任务划分相对于随机算法与均衡负载平衡算法，远程通信量分别平均降低33.7%，25.1%，负载均衡度分别平均提升56.3%，38.0%。该方法可有效降低远程通信量与提升负载均衡度。

Task dividing of network emulation for fusion of virtualization and digital simulation

Researched on the task dividing method based on the architecture of the network emulation for the fusion of virtualization and digital simulation to improve the performance. This method took into account the advantages of virtualization and digital simulation, and the emulation network topology was divided into virtualization topology area and digital simulation topology area, and then divided the two topology area combined with given physical resources aiming at load balancing and remote traffic minimizing. Extensive experiments showed that using the method to divide the network emulation task, the remote traffic was reduced by 33.7%, 25.1% averagely, and the degree of load balancing was improved by 56.3%, 38.0% averagely, compared with the random algorithm and the uniform load balancing algorithm. The task dividing method can effectively reduce the remote traffic and improve the degree of load balancing.
