FatNemo: Building a Resilient Multi-source Multicast Fat-Tree
This paper proposes the idea of emulating fat-trees in overlays for multi-source multicast applications. Fat-trees are like real trees in that their branches become thicker the closer one gets to the root, thus overcoming the “root bottleneck” of regular trees. We introduce FatNemo, a novel overlay multi-source multicast protocol based on this idea. FatNemo organizes its members into a tree of clusters with cluster sizes increasing closer to the root. It uses bandwidth capacity to decide the highest layer in which a peer can participate, and relies on co-leaders to share the forwarding responsibility and to increase the tree’s resilience to path and node failures. We present the design of FatNemo and show simulation-based experimental results comparing its performance with that of three alternative protocols (Narada, Nice and Nice-PRM). These initial results show that FatNemo not only minimizes the average and standard deviation of response time, but also handles end host failure...
