Proposal Number: 0435173PI: Jonathan TurnerInstitution: Washington University Title: Virtual Networking - Enabling Network Service Innovation Abstract: A recurring problem with communications networks is that as they grow and become more widely used, they become resistant to change. The Internet is now becoming subject to network ossification, making it difficult to deploy new capabilities to meet emerging needs. The advent of high performance network processors and advanced configurable logic devices now make it practical to virtualize the Internet, allowing multiple virtual networks to co-exist within the same physical infrastructure. This project is investigating the requirements for virtual networking architectures and the design options for realizing them.The expected results of this work include analysis of major issues that affect the design of virtual network substrates. Options by which resources are allocated from the network substrate to virtual networks are being explored. The program is also investigating alternative approaches to virtualizing end-systems and design issues for virtual data links. In addition, the program is exploring architectures for virtualized routers. Virtualization places new requirements on network processors to enable different virtual routers to share resources in a single device, without interference. Network virtualization has the potential for eliminating the recurring problem of network ossification and enabling continuing innovation in core network technologies and services. It can have a dramatic impact on the nation's information technology infrastructure, allowing much more rapid introduction of new capabilities as new needs arise.

提案编号：0435173PI：Jonathan TurnerInstitution：华盛顿大学标题：虚拟网络-支持网络服务创新摘要：通信网络的一个反复出现的问题是，随着它们的发展和越来越广泛的使用，它们变得抗拒变化。互联网现在变得容易受到网络僵化的影响，很难部署新的能力来满足新的需求。高性能网络处理器和先进的可配置逻辑设备的出现使互联网的虚拟化成为现实，允许多个虚拟网络在相同的物理基础设施中共存。该项目正在调查对虚拟网络体系结构的需求和实现这些需求的设计选项。这项工作的预期结果包括分析影响虚拟网络基板设计的主要问题。正在探索将资源从网络底层分配到虚拟网络的选项。该项目还在研究虚拟终端系统的替代方法，以及虚拟数据链路的设计问题。此外，该计划还在探索虚拟路由器的架构。虚拟化对网络处理器提出了新的要求，使不同的虚拟路由器能够不受干扰地共享单个设备中的资源。网络虚拟化有可能消除反复出现的网络僵化问题，并使核心网络技术和服务能够持续创新。它可以对国家的信息技术基础设施产生巨大影响，使其能够随着新需求的出现而更快地引入新功能。
