This proposal is developing a set of technologies to create federated content distribution utilities that support the simultaneous delivery of a wide variety of content to overlapping sets of clients with statistical quality of service assurances. The federated content distribution infrastructure will: i) simultaneously meet the performance demands of high-bandwidth and low-latency content delivery and the resource allocation constraints of constituent service providers; ii) weather a variety of attacks both from the outside and from self-interested or malicious nodes directly participating in the protocol; iii) incorporate basic algorithms for distributing content under a wide variety of dynamic network conditions. Because the infrastructure is shared by a variety of applications and hosted by a number of mutually distrustful administrative domains, the system must provide mechanisms that both adjudicate among competing applications and allow each administrative domain to maintain its own resource allocation policies.If successful this research will effect a qualitative shift in: i) the way in which data is distributed across the Internet; ii) basic algorithms for determining optimal data distribution strategies across arbitrary data meshes; iii) the levels of reliabilityand performance that can be achieved in critical nation-wide or global-scale event notification systems (e.g., the air-traffic control system); and iv) the ability of resource-poor providers to harness federated distribution utilities to publish urgent content such as Internet worm or virus signatures on a global scale.

该提案正在开发一套技术，以创建联合内容分发实用程序，这些实用程序支持同时向重叠的客户端提供各种各样的内容，并提供统计服务质量保证。 联合内容分发基础设施将：i）同时满足高带宽和低延迟内容交付的性能需求以及组成服务提供商的资源分配约束; ii）经受住来自外部以及来自直接参与协议的自私或恶意节点的各种攻击; iii）结合用于在各种动态网络条件下分发内容的基本算法。 由于基础设施由各种应用程序共享，并由许多相互不信任的管理域托管，因此系统必须提供在竞争应用程序之间进行裁决的机制，并允许每个管理域维护自己的资源分配策略。ii）用于确定跨任意数据网格的最佳数据分布策略的基本算法; iii）在关键的全国范围或全球规模的事件通知系统中可以实现的可靠性和性能的水平（例如，空中交通管制系统）;以及iv）资源贫乏的供应商利用联合分发实用程序在全球范围内发布紧急内容（例如因特网蠕虫或病毒签名）的能力。
