摘要: One of the key questions in dimensioning a hybrid P2P content distribution system is that required infrastructure support terms server bandwidth. In this paper, we develop and propose simple mathematical models for analyzing peer-to-peer networks. We first use deterministic fluid model to capture essential peer dynamics within single swarm, subsequently derive stochastic case multiple swarms, i.e., concurrent swarms number objects. Based on models, solutions estimating capacity swarm as well file at given level service quality. Numerical results demonstrate how approach can yield substantial performance gains savings compared pure client/server system, with churn rate upload bandwidth being critical factors. Compared scenario, dramatically boost improve reliability.
