摘要Abstract: The success of swarming content delivery has motivated
a new approach to live Peer-to-Peer (P2P) streaming that
we call mesh-based streaming. In this approach, participating
peers form a random mesh and incorporate swarming content
delivery to stream live content. Despite the growing popularity
of this approach, neither the design tradeoffs nor the basic
performance bottlenecks in mesh-based P2P streaming are well
understood.
This paper presents PRIME, the first mesh-based P2P streaming
for live content that effectively incorporates swarming content
delivery. We identify two performance bottlenecks in a meshbased
P2P streaming, namely bandwidth bottleneck and content
bottleneck. We derive proper peer connectivity to minimize
bandwidth bottleneck as well as an efficient pattern of delivery for
live content over a random mesh to minimize content bottleneck.
We show that the pattern of delivery can be divided into diffusion
and swarming phases and then identify proper packet scheduling
algorithm at individual peers. Using ns simulations, we examine
key characteristics, design tradeoffs and the relationship between
main system parameters.
