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.

该提案正在开发一组技术，以创建联合内容分销公用事业，以同时交付各种内容，以与统计服务质量保证的重叠客户集。 联合内容分配基础架构将：i）同时满足高宽带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）从外部和直接参与该协议的自身利益或恶意节点中进行各种攻击； iii）合并基本算法，用于在各种动态网络条件下分发内容。 由于基础架构由各种应用程序共享，并由许多相互不信任的管理领域托管，因此该系统必须提供机制，这些机制既可以在竞争应用中进行裁决，又允许每个行政域能够维持其自身的资源分配政策。如果成功，此研究将在以下方式中造成质量变化：i）i）i）在互联网上分发了哪些数据的方式； ii）确定跨任意数据网络的最佳数据分布策略的基本算法； iii）在关键的全国或全球规模事件通知系统（例如，空中交通控制系统）中可以达到的可靠性和性能水平； iv）资源贫乏的提供商可以利用联合分销公用事业在全球范围内发布紧急内容（例如Internet Worm或病毒签名）的能力。
