Peer-to-Peer Batching Policy for Video-on-Demand System

Abstract

Multicast and Peer-to-Peer (P2P) are two common transmission strategies to provide scalable and cost efficient solutions for Video-on-Demand (VoD) services. It is noted that a native P2P mechanism requires small server resources and provides an insensitive delay to users. However, the bandwidth requirement inside the network is rapidly increased when more customers joins the video session. On the other hand, if the system simply uses a multicast scheme to deliver the video, the customers have to wait for a noticeable delay before watching the videos whereas the overall bandwidth requirement will not be significantly increased. In this paper, a new transmission policy denoted peer-to-peer batching (PPB) policy is proposed to exploit the multicast capability of the network and P2P paradigm to efficiently deliver video data to the clients. Our analysis shows that the proposed PPB scheme achieves better system performance when compared with Patching (a native multicast system) and DirectStream (a native P2P system).

Enhanced Peer-to-Peer Batching Policy for Video-on-Demand System

“…In order to tackle the problem of native P2P and native multicast transmission strategies mentioned in Section I, a new transmission policy denoted peer-to-peer batching (PPB) policy has recently proposed [5] to explore the multicast delivery coupled with P2P transmission strategy for video streaming such that takes benefit from both transmission schemes to efficiently deliver video data to the clients.…”

“…On the other hand, if the system simply uses a multicast scheme to deliver the video, the customers have to wait for a noticeable delay before watching the videos whereas the overall bandwidth requirement will not be significantly increased. Recently, Ho et al [5] have developed a new transmission strategy to provide true VoD services in multicast environment. With their peer-to-peer batching (PPB) policy, customers can enjoy the video without incurring a noticeable startup delay and also reduces the overall bandwidth requirement.…”
