摘　　要：通用对等网仿真器(GPS)采用宏模型,是目前比较好的支持对等网文件下载BitTorrent协议且具有开源代码的仿真器。本文针对其存在的精确性方面的不足,从宏模型、链路时延、结点动态加入或离开、参数统计功能和变形动画演示等方面加以改进。测试结果验证了改进方案的有效性,对深入研究BitTorrent特性有较大的实际意义。The General Peer.to-peer Simulator（GPS） that adopts a macro-model not only supports the BitTorrent protocol of the P2P file downloading very well currently, but also has open source codes. However, GPS has drawbacks in terms of accuracy. Subsequently, this paper presents the improvement of GPS as well as the Lrnplementation with respect to the macro-model, link delay, dynamic node arrival or departure, parameter statistics and morph demonstration. Simulation results prove the effectiveness of the improved scheme, which is of comparatively great practical significance for studying the BitTorrent characteristics in detail.
