Serial and Parallel Transmission Models for Multi-source Streaming of Multimedia Objects

摘要

In peer-to-peer (P2P) overlay networks, source peers holding multimedia objects can transmit the multimedia objects to receiver peers. In this paper, we discuss parallel types of multi-source streaming (MSS) models where a receiver peer can receive primitive objects of a multimedia object from multiple source peers which can support enough. A multimedia object is realized in a sequence of primitive objects which are units of transmission at the P2P overlay layer. The receiver peer is required to receive primitive objects of the multimedia object with enough QoS, e.g. no primitive object loss. Multiple source peers in parallel send primitive objects to the receiver peer. In this paper, each primitive object is delivered to the receiver peer so that time to buffer the primitive object is reduced. In addition, primitive objects are duplicated by sending parity objects of the primitive objects. Here, the receiver peer can deliver every primitive object even if some primitive object is lost. We evaluate the model in terms of buffering time and delivery continuity in presence of network fault.
