NeTS-FIND: A Swarming Architecture for Internet Data Transfer

数据传输是网络的定义任务。这个项目uswarm提出了一种新颖的数据传输架构，其灵感来自于最近非常成功的群集系统，如BitTorrent。该项目追求以下，而探索性的问题：群可以形成一个通用的数据传输架构的基础，为未来的互联网，如果是这样，什么是适当的架构？具有群体性质的自然系统对于个体和整个系统都是非常鲁棒的。技术动机是使互联网数据传输：1）可扩展性，2）容错性，以及3）激励兼容性，这三个属性使用现有解决方案难以实现。uswarm的基础研究将：1）开发网络内BitTorrent类基底，其几乎递送所有数据，而不仅仅是大文件，2）利用网络内存储和数据访问的局部性，3）分析与BitTorrent类隔离群相对的一个大型集成群的可用性和人类等待时间改善，4）分析uswarm自然启用的新流量工程旋钮和路由选择，5）针对网络层面的激励问题，提出了新的激励策略。6）利用博弈论技术分析了自私行为与路由和拥塞控制的相互作用。更广泛的影响：如果成功，该项目将从根本上改善互联网数据传输，实现：1）关键信息传播抵抗拒绝信息攻击，2）延迟容忍网络应用程序，3）新型社交网络应用程序。拟议的工作包括本科以及国际教学和推广活动与拟议的研究活动相结合。

Data transfer is a defining task of a network. This project, uswarm, proposes a novel data-transfer architecture inspired by recent, tremendously successful swarming systems such as BitTorrent. The project pursues the following, rather exploratory, question: can swarms form the basis of a universal data-transfer architecture for a future Internet and if so, what is an appropriate architecture? Natural systems with swarm-like properties are known to be extremely robust both for an individual and for the system as a whole. The technical motivation is to make Internet data transfer: 1) scalable, 2) fault-tolerant, and 3) incentive-compatible, a trio of properties difficult to achieve using existing solutions. The research underlying uswarm will: 1) develop an in-network BitTorrent-like substrate deliver practically all data, not just large files, 2) exploit in-network storage and locality of data accesses, 3) analyze availability and human wait-time improvements of one large integrated swarm as opposed to BitTorrent-like isolated swarms, 4) analyze new traffic engineering knobs and routing choice naturally enabled by uswarm, 5) develop novel incentive strategies for integrated swarms accounting for network-level incentive issues, 6) analyze the interaction of selfish behavior with routing and congestion control using game-theoretic techniques. Broader Impact: If successful, this project will fundamentally improve Internet data transfer by enabling: 1) critical information dissemination resistant to denial-of-information attacks, 2) delay-tolerant network applications, and 3) novel social networking applications. The proposed work includes undergraduate as well as international teaching and outreach activities integrated with the proposed research activities.
