CrossFlux: Cooperative Networks for Content Distribution in the Internet
| Responsable du projet | Pascal Felber |
| Résumé |
Peer-to-peer (P2P) systems, in which peer computers form a
cooperative network and share their resources (storage, CPU,
bandwidth), have attracted a lot of interest lately. After the
apparition of the first truly successful P2P systems, and the
significant amount of research conducted in Academia and in the
Industry, most researchers now agree thatP2P systems are more than
just a fashion phenomenon. They offer great potential for building
cooperative networks that are self-organizing,efficient, scalable,
and reliable.Research in P2P networks has so far mainly focused on
content storage and lookup, but little work has been done about its
actual distribution. By capitalizing the bandwidth of peer nodes,
P2P architectures offer great potential for addressing some of the
most challenging issue of today's Internet: the cost-effective
distribution of bandwidth-intensive content to thousands of
simultaneous users and the resilience to "flash crowds"
(a huge and sudden surge of request traffic that usually leads to
the collapse of the affected server). In this project, we propose
to address the problem of cooperative distribution of streaming
media and large content from a networking perspective. We plan to
specifically focus on three complementary research directions:
first, the design of topology-aware P2P substrates specialized for
efficient content distribution; second, the push-based distribution
of streaming content with timing constraints, such as streaming
media (TV,radio); third, the pull-based distribution of large, but
time-insensitive stored content. Each of these research topics will
be supported upstream by extensive analysis and modeling, and
downstream by prototype implementations and experimental
validation.This project is expected to yield not only novel
research contributions,but also practical techniques for
cooperative content distribution applicable both Internet-wide and
in large private networks. These techniques can be of great
interest to media and infrastructure providers,as well as to medium
and large companies that wish to avoid the cost of dedicated Content
Delivery Networks (CDNs) for reliable content distribution. |
