CSR-PDOS: Scalable Peer-to-Peer Data Dissemination

当互联网协议在80年代后期标准化时，大多数分布式应用程序都是点对点的，例如电子邮件、telnet和ftp。在过去的几年里，互联网流量的性质发生了巨大的变化。在大量用户创建内容的生产和分发的驱动下，当前的互联网流量压倒性地是多对多的，导致应用程序需求和底层协议之间的不匹配。该项目旨在开发一种名为OneSwarm的点对点解决方案，作为多点通信的通用通信层。通过完全依赖运行在终端主机上的软件，OneSwarm将避免基础设施解决方案的高运营成本和重新设计网络架构的可部署性问题。在需要回答的开放问题中：当内容文件不再大时，当交付有严格的截止日期时，当通信不是所有对所有时，或者当不同节点有不同的需求时，所有这些都不与ISP目标交叉工作时，群集技术是否能够工作并满足期望的服务质量水平？该提案还将通过允许用户跨时间、跨集群和跨应用程序交易资源，研究鼓励终端主机贡献资源以支持高要求应用程序的激励措施。

When the Internet protocols were standardized in the late 80s, most distributed applications were point-to-point, such as email, telnet, and ftp. Over the last few years, the nature of Internet traffic has changed dramatically. Driven by the production and distribution of vast amounts of user-created content, current Internet traffic is overwhelmingly many-to-many, leading to a mismatch between application demand and the underlying protocols.This project is to develop a peer-to-peer solution, called OneSwarm, to serve as a universal communication layer for multi-point communication. By relying solely on software running on end-hosts, OneSwarm will avoid the high operational cost of infrastructure solutions and the deployability issues of clean-slate redesigns to the network architecture. Among the open questions that need answers: can swarming techniques work and meet desired levels of service quality when content files are no longer large, when there are strict deadlines on delivery, when the communication is not all-to-all, or when different nodes have different needs, all without working at cross-purposes to ISP objectives? This proposal will also investigate incentives to encourage end hosts to contribute resources to support demanding applications, by allowing users to trade resources across time, across swarms, and across applications.
