Abstract

Recent advances in P2P technology have made it a viable alternative for the delivery of rich media by both content and service providers. However, to better understand and utilize P2P technologies in building a scalable media distribution platform, the nature of the underlying network must be taken into consideration. Although many P2P simulations have been conducted previously, very few were evaluated on a real P2P testbed with the properties of the physical network in mind. In this paper, we describe VP2P, a virtual machine-based P2P testbed, which supports P2P studies with the consideration of typical service provider networks. We use four fully equipped MacPro's to emulate 32 peers in the current implementation. Experiments of three P2P algorithms for Video On Demand (VoD) services: BitTorrent, Toast, and Zebra, were run on the testbed. We discuss the rationales behind the hardware and software architecture of VP2P, report our results, and conclude with lessons learned and future directions for VM-based testbeds.
VP2P:基于虚拟机的点对点视频点播测试平台
P2P技术的最新进展使其成为内容和服务提供商提供富媒体的可行替代方案。然而,为了更好地理解和利用P2P技术来构建可扩展的媒体分发平台,必须考虑底层网络的性质。虽然以前已经进行了许多P2P模拟,但很少有在真实的P2P测试平台上进行评估,并考虑到物理网络的属性。本文介绍了一种基于虚拟机的P2P测试平台VP2P,该平台支持基于典型服务提供商网络的P2P研究。在当前的实现中,我们使用四个完全配备的MacPro来模拟32个对等体。在实验台上分别对BitTorrent、Toast和Zebra三种P2P点播算法进行了实验。我们讨论了VP2P硬件和软件架构背后的基本原理,报告了我们的结果,并总结了经验教训和基于vm的测试平台的未来方向。
