Efficient Usage of Network Bandwidth in the Cloud Architecture

Abstract

The cloud computing emphasizes that any resources can be services provided to users. For IaaS, virtualization technologies leverage the use of hardware to serve users without complicated applying procedures. As we know, any physical resources, such as CPU, memory or bandwidth, are precious in general so that they should be used as well as possible. Many researches hence are booming aiming at performance enhancement, especially for cloud networking. The paper presents hardware and software-based concepts to let virtual machines use bandwidth of physical machines under best-effort provisioning. The result can benefit IaaS architecture running from less waste of bandwidth.
