基于云计算的智慧校园虚拟网络节点定位研究

Research on Node Localization of Intelligent Campus Virtual Network Based on Cloud Computing

基于新兴的智慧校园网络技术,论文将Mininet虚拟网络与Openvswitch真实交换机融合,搭建一个智慧校园虚实网络环境,以同时满足网络大规模和真实性的需求。在智慧校园虚实网络拓扑中,一个关键问题是如何选择Open-vswitch交换机,即真实节点的位置。论文结合图论和社交网络等领域的概念,设计了真实节点的定义,并提出了基于节点介数分析的真实节点查找算法和基于重叠社区发现的真实节点查找算法。通过3个不同网络拓扑的实验,验证了论文提出的算法能够有效发现拓扑中真实节点的位置,对搭建大规模且真实的智慧校园虚实网络具有重要意义。

Based on the emerging smart campus network technology,this paper integrates the Mininet virtual network and Openvswitch real exchange integration to build a virtual smart campus network environment,so as to meet the needs of large-scale network and authenticity at the same time.In the smart campus virtual network topology,a key issue is how to select the Open?vswitch switch,that is,the location of the real node.This paper combines with the concept of graph theory and social network and other fields,designes the definition of real nodes,and puts forward the real node search algorithm of node betweenness based on re?al node search algorithm for detecting overlapping communities.Through experiments on 3 different network topologies,it is proved that the proposed algorithm can effectively find the location of real nodes in topology,and it is of great significance for building large-scale and real intelligent campus virtual network.
