Multi-paths Streaming and Dynamics End-points Adaption
(John C.S. Lui)

Currently, if one want to view a video on the Internet with the quality-of-service (QoS) guaranteed, one has to rely on the IntServ model, that is, QoS via resource reservation of different RSVP-enable routers. However reserving resource may not be a scalable solution. In this research, we examine the possibility of providing QoS without network resource reservation. The main idea is to perform parallel video streaming from different sources. If there is any transient network congestion within a path, the client should dynamically adapt to the congestion situation and to switch partial traffic from the congested source to another source. This type of parallel streaming and dynamic adaptation requires a loose synchronization among servers and the dynamic statistical measurements from client so as to determine the shared point-of-congestion. Simulation and system implementation will be carried out to demonstrate this novel streaming technique.
