LayStream: composing standard gossip protocols for live video streaming
Miguel Matos, Valerio Schiavoni, Etienne Rivière, Pascal Felber & Rui Oliveira
| Résumé |
Gossip-based live streaming is a popular topic, as attested by the
vast literature on the subject. Despite the particular merits of
each proposal, all need to implement and deal with common
challenges such as membership management, topology construction and
video packets dissemination. Well-principled gossip-based protocols
have been proposed in the literature for each of these aspects. Our
goal is to assess the feasibility of building a live streaming
system, LAYSTREAM, as a composition of these existing protocols, to
deploy the resulting system on real testbeds, and report on lessons
learned in the process. Unlike previous evaluations conducted by
simulations and considering each protocol independently, we use
real deployments. We evaluate protocols both independently and as a
layered composition, and unearth specific problems and challenges
associated with deployment and composition. We discuss and present
solutions for these, such as a novel topology construction
mechanism able to cope with the specificities of a large-scale and
delay-sensitive environment, but also with requirements from the
upper layer. Our implementation and data are openly available to
support experimental reproducibility. |
