Abstract

In the past few years numerous P2P file-sharing and content distribution systems have been designed, implemented, and evaluated via simulations, real world measurements, and mathematical analysis. Yet, only few of them have stood the test of time and gained wide user acceptance. BitTorrent is the one that holds the lion's share among them and the reasons behind its success have been studied to a great extent with interesting results. Nevertheless, even though P2P content distribution remains one of the most active research areas, little progress has been made towards the study of the BitTorrent protocol (and its variations), in a fully controllable and realistic simulation environment. In this paper we describe and analyze a full-featured and extensible implementation of BitTorrent for the OMNeT++ simulation platform. Moreover, since we aim at realistic simulations, we present our enhancements on a popular conversion tool for practical Internet topologies, as well as our churn generator that is based on the analysis of real BitTorrent traces. Finally, we set forth the results from the evaluation of our prototype implementation regarding resource demands under different simulation scenarios.

omnet++模拟器的BitTorrent模块

在过去的几年中，许多P2P文件共享和内容分发系统已经被设计、实现，并通过模拟、真实世界的测量和数学分析进行了评估。然而，它们中只有少数经受住了时间的考验并获得了广泛的用户接受。BitTorrent是其中占有最大份额的一个，其成功背后的原因在很大程度上得到了有趣的研究结果。然而，尽管P2P内容分发仍然是最活跃的研究领域之一，但在完全可控和现实的模拟环境中，对BitTorrent协议(及其变体)的研究进展甚微。在本文中，我们描述和分析了一个功能齐全、可扩展的BitTorrent在omnet++仿真平台上的实现。此外，由于我们的目标是真实的模拟，我们提出了我们的增强在一个流行的转换工具，为实际的互联网拓扑，以及我们的流失生成器，是基于真实的BitTorrent痕迹的分析。最后，我们给出了原型实现在不同仿真场景下对资源需求的评估结果。
