摘要: Gossip-based protocols for group communication have attractive scalability and reliability properties. The probabilistic gossip schemes studied so far typically assume that each member has full knowledge of the global membership chooses targets uniformly at random. requirement impairs their applicability to very large-scale groups. In this paper, we present SCAMP (Scalable Membership protocol), a novel peer-to-peer protocol which operates in fully decentralized manner provides with partial view membership. Our is self-organizing sense size views naturally converges value required support algorithm reliably. This function size, but achieved without any node knowing size. We propose additional mechanisms achieve balanced sizes even highly unbalanced subscription patterns. design, theoretical analysis, detailed evaluation basic its refinements. Simulation results show guarantees provided by are comparable previous based on knowledge. scale experiments attests protocol.
