Providing Probabilistic Performance Guarantees in Multi-Source Video Streaming over the Internet
P. Y. Ho, Verboven Sam, Jack Y. B. Lee · 2006
The current best-effort Internet does not guarantee bandwidth availability between a receiver and a sender, and so renders any quality-of-service (QoS) control difficult, if not impossible. This paper approaches this QoS challenge from a different angle – streaming video not from one, but from multiple senders to a receiver. Our investigation reveals that the aggregate bandwidth from multiple senders, while still varies randomly, is far more predictable than a single sender. This increased predictability enables us to devise probabilistic QoS control algorithms to achieve near-optimal performance even in the best-effort Internet. This paper reports our initial findings from trace-driven simulations using synthetic as well as real Internet traffic traces.
