Recently, there has been a growing interest in academic and commercial environments for Video-on-Demand (VoD) using Peer-to-Peer (P2P) technology. Unlike centralized solutions for VoD services, P2P technology lets the clients distribute video content among themselves. In this paper, we propose an analytical model for P2PVoD and we compare that model to a realistic P2PVoD simulator. With our model, parameters that affect the system performance can be observed, and the system stability can be

Related work Guo et al. [3] and Qiu et al. [4] model mesh-based P2P le sharing analytically and present a performance study combined with extensive measurements. Kumar et al. [5] proposed a uid model for mesh-based P2PTV, which has only one seed. Lu et al. [6] proposed a mesh-based model for P2PTV and compared its blocking to that of IPTV. However, the models in [5] and [6] are not applicable to P2PVoD. Some research works (e.g., [7], [8] ) target mesh-based P2PVoD, but only use simulations to analyze which kind of chunk-scheduling method can achieve the best performance. The proposed system by Chi et al. [9] was evaluated with the help of analytical models, but what they analyzed is tree-based P2PVoD, not mesh-based P2PVoD. Prior to this work, an analytical model of mesh-based P2PVoD seemed missing.
