摘要: We present the design, correctness, and analysis of SONDe, a simple fully decentralized object deployment algorithm for highly requested systems. Given an (service or data), SONDe provides node with constant upper bound (h) on number logical hops to access holder (provider), thus making tunable predictable communication latency between any provider. In addition, is able dynamically adapt providers reflect load variations experienced in localized portions system. Each individually decides be provider, based observation its h-hops neighborhood. show theoretically that self-stabilizes independent-dominating set providers. Finally simulation results, conducted over different network topologies, demonstrate efficiency approach confirm theoretical analysis.
