Abstract:

Multi-source streaming is essential for the design of a
large-scale P2P streaming architecture. In this paper, we focus on
improving the dependability of multi-source video streaming as
an alternative to the more prevalent point-to-point streaming.
We have designed and implemented a dynamic FEC (D-FEC)
protocol for multi-source video streaming. Our D-FEC protocol
has the ability to dynamically switch between 4 different FEC
techniques to adapt to varying network conditions. A
comprehensive performance evaluation was performed with a
full-scale system prototype that gives insights into the behavior of
the different adaptive FEC schemes, and shows the feasibility of
the concept of switching FEC schemes during a streaming
session. Guidelines are given in order to best design a FEC
protocol switching strategy taking into account the experienced
loss rate, the loss burstiness, and the original video stream rate.
