基于OpenStack平台的网络拓扑虚拟静态路由自动配置技术研究

Research on Auto-configuration of Virtual Static Routing of the Topological Network Based on OpenStack Platform

随着虚拟化技术的发展,云平台虚拟网络配置技术逐渐成为研究的热点。然而,当前研究主要集中在对路由的设计、均衡负载技术的研究,而对实际工程中网络拓扑的静态路由配置问题缺少较为详细的探讨。文章基于OpenStack环境和结构,由双层深度优先搜索出发,提出了一种启发式的静态路由配置算法,并在平台上进行了试验。结果表明,经过改进和优化,该静态路由配置算法在非成环拓扑下和复杂成环拓扑下都有良好的效果。最后文章针对当前算法的不足进行了分析并提出了相关的改进措施。

With the development of virtualization technology, virtual network configuration technology on cloud platform has become a hot spot of research. However, the current research mainly focuses on the router design and load-balancing technology without taking detailed research on the static route auto-configuration technology of topology network in real practice. This paper presents a heuristic static routing configuration algorithm based on double-layer depth-first-search in OpenStack environment. This paper has carried out an implementation on OpenStack platform, and the results show that after optimization, the static routing configuration algorithm works well in both acyclic and cyclic topologies. Finally, this paper analyses the shortcomings of the current algorithm and puts forward relevant improvement measures.
