CSR -- SMA: Bridging Analytical and Empirical Understanding of Churn in Decentralized P2P Systems

摘要对等网络（P2P）系统近年来已经发展成为一个复杂的、自组织的实体，为许多互联网应用提供了一个可扩展的、高效的、分散的平台。为了支持和继续扩展这一重要领域，该项目开发了用户流失下的P2P网络的基本分析和实验理解，这是一个描述P2P系统动态行为的术语，其中到达和离开不同步。这项工作建立在三个组件的协同作用-分析建模的客户流失，弹性和路由性能的异构P2P网络;实验抽样的客户流失和验证所获得的结果在真实的网络;和P2P研究整合到研究生和本科生教育在得克萨斯州A M大学。该项目的预期影响是提供对新兴P2P网络的更深入了解，并向广泛的受众揭示这些系统的新颖理论，实验和教育方面。

AbstractPeer-to-peer (P2P) systems have recently evolved into complex, self-organizing entities that provide a scalable, efficient, and decentralized platform for many Internet applications. To support and continue expanding this important field, this project develops fundamental analytical and experimental understanding of P2P networks under user churn, which is a term describing dynamic behavior of P2P systems in which arrivals and departures are not synchronized. This work builds upon a synergy of three components - analytical modeling of churn, resilience, and routing performance of heterogeneous P2P networks; experimental sampling of churn and verification of obtained results in real networks; and integration of P2P research into graduate and undergraduate student education at Texas A&M University. The expected impact of the project is the delivery of a deeper understanding of emerging P2P networks and unveiling of novel theoretical, experimental, and educational aspects of these systems to a broad range of audiences.
