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，更广泛地说，用于将破坏性技术引入互联网。然而，迫切需要一种试验床，使研究社区能够在真实世界的条件下大规模地试验覆盖服务。拟议中的项目将扩大和增强一个名为PlanetLab的全球覆盖网络，该网络就是提供这种能力的。要对PlanetLab软件进行的增强包括：-实施系统级机制，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，以监控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负责的个人；-提供机制，允许研究人员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；以及提供收集、存档和分析在PlanetLab上收集的性能数据所需的仪器挂钩和测量工具。更广泛的影响和智力价值：Pi的设想行星实验室作为下一代互联网的缩影。对于网络研究社区，PlanetLab提供了重新获得现在已经失去的能力的机会，可以快速、无缝地从想法到评估再到实践。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，并提供了一系列支持它的课件和工具。对于更广泛的用户社区、商业开发商和整个社会，它提供了一条重新激活创新过程的途径，该过程已导致新的互联网服务、广泛的消费者采用和产生新的经济和社会价值。这项提议旨在增强软件基础并增加PlanetLab的节点数量，PlanetLab是一个全球覆盖网络，将作为研究试验台和部署平台。它可以通过允许研究人员在真实世界的条件下进行大规模实验，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.
