在对等（P2P）覆盖网络中，多媒体对象分布在对等体中，并且源对等体向接收对等体发送多媒体对象。在本文中，我们想讨论如何多个源端提供多媒体对象接收端的流模型，以便在存在的QoS变化的服务质量（QoS）需要足够的支持。一个多媒体对象被实现在一个原始对象的序列，这些原始对象是在P2P覆盖层的传输单元。要求接收端以足够的QoS接收多媒体对象的原语对象，例如没有原语对象丢失。我们讨论了多源流（MSS）模型的类型，其中接收端可以从多个源端接收多媒体对象的原始对象，这些源端可以支持足够的QoS。MSS模型有串行和并行类型。在串行MSS模型中，接收端每次从一个源端接收每个原语对象。如果期望当前源对等体支持比所需更低的QoS或者不支持后续原语对象，则另一个源对等体开始发送原语对象。在并行MSS模型中，多个源对等体并行地向接收对等体发送原始对象单元。原语对象由多个源对等体冗余地发送或由源对等体非冗余地发送。在这里，可以增加吞吐量和可靠性。
In peer-to-peer (P2P) overlay networks, multimedia objects are distributed in peers and source peers transmit a multimedia object to receiver peers. In this paper, we would like to discuss how multiples source peers deliver multimedia objects to receiver peers in a streaming model so that enough quality of service (QoS) required is supported in presence of QoS change. 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. We discuss 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 QoS.There are serial and parallel types of MSS models. In the serial MSS model, a receiver peer receives each primitive object from one of the source peers at a time. If a current source peer is expected to support lower QoS than required or not to support a succeeding primitive object, another source peer starts sending primitive objects. In the parallel MSS model, multiple source peers in parallel send primitive object units to the receiver peer. A primitive object is redundantly sent by multiple source peers or non-redundantly sent by a source peer. Here the throughput and reliability can be increased.
