A priority based virtual network bandwidth guarantee method in software defined network
Qu Fu, Qing Min Liao, An Yingzhu, Fan Yamei · 2015
Virtual Network (VN) bandwidth guarantee is an important issue in scenarios such as enterprise network and multi-tenant datacenter. The Software Defined Network (SDN) is sophisticated technology for network control and management. In this paper we proposed a VN bandwidth guarantee method which use SDN controller and Open vSwitch to allocate the available bandwidth by VN's priority. According to simulation results, the proposed method can effectively guarantee the bandwidth for VNs while maximizing the bandwidth utilization.
