As virtualization spreads throughout the data center, the communication endpoints within the data center are becoming virtual machines (VMs), not physical servers. Therefore, the network facilities for packet processing and security must operate all the way to the VM. This last hop switching among virtual machines within the physical server has become a critically important component of the data center network. This project will explore the design space of server/switch integration, in which software and hardware based switching are more efficiently integrated directly into the server. More specifically, it will decouple the switching operations and distribute their implementation throughout the virtualized system. This project will be comprised of the following thrusts: - Efficient Software Switching via a decoupled software switching architecture using a flow-based approach that eliminates these overheads and that enables efficient switching in software - Judicious choice and use of hardware acceleration. - The Rack Becomes the Server via having the network control plane learning the hardware topology, monitoring the network traffic, instructing the hypervisor to move communicating VMs closer to each other. As the demand for data center capacity continues to increase at an incredible rate, it is becoming critical to minimize the number of physical machines. This research will transform the way in which networking is implemented on future systems, enabling the effective use of 100s of virtual machines per physical machine. This reduction in physical machines can have significant societal and economic impacts. If U.S. data centers used virtualization technology to achieve just half of the power reductions predicted by Intel, we would save $3.5 billion of electricity and prevent the release of 322 million pounds of CO2 per year.

随着虚拟化在整个数据中心的传播，数据中心内的通信端点正在变成虚拟机（vm），而不是物理服务器。因此，用于数据包处理和安全的网络设施必须一直运行到虚拟机。这种物理服务器内虚拟机之间的最后一跳交换已经成为数据中心网络的一个至关重要的组成部分。本项目将探索服务器/交换机集成的设计空间，将基于软件和硬件的交换更有效地直接集成到服务器中。更具体地说，它将分离交换操作，并在整个虚拟化系统中分发它们的实现。该项目将由以下重点组成：-通过使用基于流的方法消除这些开销的解耦软件交换架构实现高效软件交换，从而实现软件中的高效交换-明智的选择和使用硬件加速。—通过网络控制平面学习硬件拓扑，监控网络流量，指示虚拟化环境将通信的虚拟机移动到更近的位置，使机架变成服务器。随着对数据中心容量的需求继续以惊人的速度增长，减少物理机器的数量变得至关重要。这项研究将改变在未来系统上实现网络的方式，使每台物理机器能够有效地使用100个虚拟机。物理机器的减少可以产生重大的社会和经济影响。如果美国的数据中心使用虚拟化技术实现英特尔预测的一半的电力削减，我们每年将节省35亿美元的电力，并防止3.22亿磅的二氧化碳排放。
