VNE-Greedy: Virtual Network Embedding Algorithm Based on OpenStack Cloud Computing Platform

Abstract

A new approach to implementation of the virtual network embedding strategy over OpenStack cloud platform presented. We presented the OpenStack cloud platform and the problems associated with virtual network embedding. Then, conduct OpenStack dashboard customization to generate virtual network requests to process these requests. We modified OpenStack Compute module to provide bandwidth limitation for the virtual network requests, as well as modification of the data structure used between the OpenStack Horizon and Nova modules, implementing virtual network embedded algorithm (VNE-Greedy) on the top of OpenStack cloud platform.
