Network Interface Virtualization: Challenges and Solutions

時間：2013年3月25日 地點：九龍湖校區計算機樓313室

報告簡介：

Recently Computer Virtualization has become an important technology in nearly every large organization's IT infrastructure. At its core, computer virtualization allows a single physical machine to be split into several Virtual Machines (VMs). Through the use of VMs, organizations can decrease operational costs through server consolidation and better utilization of computational resources. VMs also allows organizations to outsource their computational requirements to utility computing platforms such as cloud computing. The benefit of computer virtualization comes together with overhead, affecting virtually every subsystem, particularly the network subsystem that involves both hardware and software components and both local and remote accesses. This talk will offer an intuitive understanding of state-of-the-art software-based virtual network interfaces and the causes of virtualization overhead through both system analysis and real experiments. We will use TCP-based Denial-of-Service attack and Dropbox file synchronization as cases to illustrate the impact. We will further discuss the recent hardware advances in this field as well as the challenges yet to be addressed.
