Distributed Coordination for Scalable Multimedia Streaming Model

Abstract

We discuss how to realize the multimedia streaming service by using multiple peers in a peer-to-peer (P2P) overlay network. Here, multimedia contents are required to be reliably delivered to processes in a real-time manner. Multimedia contents are distributed to peers in various ways like downloading. A peer which holds a content can provide other peers with the content. In our distributed multi-source streaming model, a collection of peers in parallel and redundantly transmit packets of a multimedia content to a requesting peer to realize the reliability and scalability without centralized controller. Even if some peer is faulty and packets are lost and delayed, a requesting peer receives every data of a content at the required rate. Furthermore, multiple peers start transmitting packets to a leaf peer and change packets to be transmitted and transmission rate without centralized controller to support shorter response time.
