EIN: Collaborative Research; PlanetLab: An Overlay Testbed for Disruptive Network Services

覆盖网络最近作为一种很有前途的技术出现，用于部署新的网络服务，更一般地说，用于将颠覆性技术引入互联网。然而，迫切需要一个试验台，使研究团体能够在实际条件下大规模地试验覆盖服务。拟议中的项目将建立并增强一个名为PlanetLab的全球覆盖网络，该网络将提供这样的能力。PlanetLab软件的增强功能包括：-实现系统级机制，将实验服务彼此隔离，并保护网络免受故障和恶意流量的影响；-建立机制来监控PlanetLab节点和服务的健康状况，诊断意外行为，并将可疑行为映射到责任人；-提供机制，使研究人员能够发现满足其需求的可用PlanetLab节点集，并根据尊重资源可用性的市场获取这些节点上的资源；并提供收集、存档和分析行星实验室收集的性能数据所需的仪器挂钩和测量工具。更广泛的影响和知识价值：PI设想PlanetLab作为下一代互联网的缩影。对于网络研究社区来说，PlanetLab提供了一个机会，让他们重新获得现在已经失去的快速无缝地从想法到评估再到实践的能力。对于教育界来说，它为教学和实验提供了一个丰富而现实的平台，以及一组课件和工具来支持它。对于更广泛的用户社区、商业开发人员和整个社会来说，它提供了一条重新激发创新过程的途径，这种创新过程导致了新的互联网服务、广泛的消费者采用和新的经济和社会价值的产生。该提案旨在增强软件基础，并在PlanetLab中构建节点数量，PlanetLab是一个全球覆盖网络，将作为研究测试平台和部署平台。通过允许研究人员在实际条件下进行大规模实验，它可以在帮助定义下一代（覆盖）互联网方面发挥潜在的重要作用。

Overlay networks have recently emerged as a promising technique for deploying new network services, and more generally, for introducing disruptive technology into the Internet. However, there is a pressing need for a testbed that allows the research community to experiment with overlay services at scale, and under real-world conditions. The proposed project will build-out and enhance a global overlay network, called PlanetLab, that provides just such a capability. Enhancements to be made to the PlanetLab software include the following:-Implement system-level mechanisms that isolate experimental services from each other, and protect the network from faulty and malicious traffic;-Build mechanisms to monitor the health of PlanetLab nodes and services, diagnose unexpected behavior, and map suspicious behavior to the responsible individuals;-Provide mechanisms to allow researchers to discover the set of available PlanetLab nodes that meet their needs and acquire resources on those nodes according to a market that respects resource availability; and provide the instrumentation hooks and measurement tools needed to collect, archive, and analyze performance data collected on PlanetLab. Broader Impact and Intellectual Merit: PI's envision PlanetLab serving as a microcosm for the next generation Internet. For the networking research community, PlanetLab offers the opportunity to regain the now-lost ability to rapidly and seamlessly move from idea to evaluation to practice. For the educational community, it offers a rich and realistic platform for teaching and experimentation, and a body of courseware and tools to support it. For the broader community of users, commercial developers, and society at large, it offers a path to re-energizing the innovative process that has led to new Internet services, widespread consumer adoption and generation of new economic and social value. This proposal aims to enhance the software substrate and build out the number of nodes in PlanetLab - a global overlay network that will serve as both a research testbed and a deployment platform. It can play a potentially momentous role in helping define a next generation (overlay) Internet by allowing researchers to experiment at scale and under real-world conditions.
