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，如电子邮件、远程登录和ftp。在过去的几年里，互联网流量的性质发生了巨大的变化。在海量用户创建内容的生产和分发的推动下，当前的互联网流量绝大多数是多对多的，导致应用需求和底层协议之间的不匹配。该项目旨在开发一个称为OneSarm的对等解决方案，作为多点通信的通用通信层。通过仅依赖在终端主机上运行的软件，OneSarm将避免基础设施解决方案的高昂运营成本，以及重新设计网络架构的可部署性问题。需要回答的问题包括：当内容文件不再很大、交付有严格的截止日期、通信不是万能的、或者不同的节点有不同的需求时，群聚技术是否可以工作并满足预期的服务质量级别，而所有这些都不会与运营商的目标背道而驰？该提案还将调查激励措施，通过允许用户跨时间、跨群体和跨应用程序交换资源，鼓励终端主机贡献资源来支持要求苛刻的应用程序。

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.
