虚拟网络影射仿真平台ALEVIN的改进与实现
发布时间：2018-08-01 13:14
【摘要】：网络虚拟化旨在解决现代网络架构的僵化问题。虚拟网络映射是网络虚拟化的一个重要研究点,目前已经有多种虚拟网络映射算法,因此急需一个集成仿真平台用于算法的性能比较。ALEVIN是虚拟网络影射的代表性开源仿真平台,集成了许多启发式算法,但ALEVIN不能自由生成网络拓扑环境。为弥补ALEVIN该缺陷,文中在ALEVIN上设计和实现了该功能,且开源可下载。此外,文中提出了一种精确解影射算法并添加到ALEVIN中。同时启用添加的网络拓扑环境生成功能,将该精确解算法与典型的启发式算法进行了性能比较。
[Abstract]:Network virtualization aims to solve the rigid problem of modern network architecture. Virtual network mapping is an important research point in network virtualization. At present, there are many virtual network mapping algorithms. Therefore, there is an urgent need for an integrated simulation platform to compare the performance of the algorithm. ALEVIN is a representative open source simulation platform for virtual network mapping. Many heuristic algorithms are integrated, but ALEVIN can not generate network topology environment freely. In order to make up for this defect of ALEVIN, this function is designed and implemented on ALEVIN, and the open source is downloadable. In addition, an exact unmapping algorithm is proposed and added to ALEVIN. At the same time, the added network topology environment generation function is enabled, and the performance of the exact solution algorithm is compared with that of the typical heuristic algorithm.
