Multi-path Streaming: Is It Worth the Trouble? Leana Golubchik* Computer Science Department, ISI and IMSC University of Southern California Los Angeles, CA 90089 leana@cs.usc.edu. Quality of service (QoS) in streaming of continuous media over the Internet is still poor and inconsistent. The degradation in quality of continuous media applications, involving delivery of video and audio, is partly due to variations in delays as well as losses experienced by packets sent through wide-area networks. Although many such applications can tolerate some degree of missing information, significant losses degrade an application's quality of service. One approach to providing QoS for continuous media applications over the Intemet is to use the IntServ model for signaling (e.g., RSVP) and resource reservation in all routers along the streaming path. However, this approach suffers from scalability and deployment problems. In contrast, in our work we investigate the potential benefits of providing QoS guarantees in continuous media delivery through the exploitation of multiple paths existing in the network between a set of senders and a receiver. One advantage of this approach is that the complexity of QoS provision can be pushed to the network edge and hence improve the scalability and deployment characteristics while at
