While we are increasingly dependent on networked, distributed systems, current distributed systems require extensive manual effort to deploy, are expensive to administer, and tend to be fragile nevertheless. These problems stem fundamentally from the fact that current distributed systems lack principled design and depend on unreliable heuristics for their operation.We are investigating new techniques for building robust, high-performance infrastructure services, based on novel analytical and numerical techniques for optimally or near-optimally performing resource allocation in large-scale distributed systems. We are developing new techniques that enable a new generation of highly reliable, self-organizing infrastructure services. In particular, we are developing a next-generation name service to replace the Domain Name Service that seamlessly supports the existing name hierarchy, a high-performance web cache that achieves predictably high performance by delivering hot data items close to clients proactively, and an eternal software repository that minimizes download time for swarming, bittorrent-style downloads. This work lays a foundation for a principled understanding of resource tradeoffs in distributed systems that are currently performed either manually or in an ad hoc fashion. The new techniques are directly applicable to self-organizing peer-to-peer systems and lead to performance, manageability and availability properties that are difficult to achieve via conventional means. The application of these techniques to the implementation of infrastructure services will yield more robust replacements for fragile and expensive services, such as DNS, web caches, and software distribution than we use today.

虽然我们越来越依赖于联网的分布式系统，但当前的分布式系统需要大量的手动工作来部署，管理成本昂贵，而且往往很脆弱。这些问题从根本上源于这样一个事实，即目前的分布式系统缺乏原则性的设计，并依赖于不可靠的物流为他们的operation.We正在研究新的技术，用于建立强大的，高性能的基础设施服务，基于新的分析和数值技术的最佳或接近最佳的执行资源分配在大型分布式系统。我们正在开发新技术，以实现新一代高度可靠、自组织的基础设施服务。 特别是，我们正在开发下一代名称服务来取代无缝支持现有名称层次结构的域名服务、通过主动提供靠近客户端的热门数据项来实现可预测的高性能的高性能Web缓存以及永恒的软件存储库，最大限度地减少蜂拥、bittorrent风格下载的下载时间。这项工作奠定了一个原则性的理解，在分布式系统中，目前手动或在一个特设的方式进行的资源权衡的基础。这些新技术直接适用于自组织对等系统， 通过常规手段难以实现的稳定性和可用性。将这些技术应用于基础设施服务的实现，将为脆弱和昂贵的服务（如DNS、Web缓存和软件分发）提供比我们今天使用的更强大的替代品。
