Gossip Membership Management with Social Graphs for Byzantine Fault Tolerance in Clouds
Abstract
As computer systems have become more complex and dynamic, unstructured and decentralized techniques serve as basic building blocks in large-scale systems such as cloud computing systems. In particular, we consider a gossip-based algorithm, one of the unstructured overlay construction techniques. In this paper, we propose a membership management mechanism using the gossip-based algorithm with social graphs for the Byzantine fault tolerance problem. Experimental results show that our membership management mechanism copes with Byzantine nodes effectively in a scalable way without a bottleneck in dynamic computing environments, requiring only n ≥ 2f + 1 nodes.
