HEAP: Heterogeneity-aware gossip protocol.

Participants : Davide Frey, Anne-Marie Kermarrec.

This work has been done in collaboration with Vivien Quéma (CNRS Grenoble), Maxime Monod and rachid Guerraoui (EPFL), and has lead to the development of a video streaming platform based on HEAP, HEterogeneity-Aware gossip Protocol . The platform is particularly suited for environment characterized by heterogeneous bandwidth capabilities such as those comprising ADSL edge nodes. HEAP is, in fact, able to dynamically leverage the most capable nodes and increase their contribution to the protocol, while decreasing by the same proportion that of less capable nodes.
