Description
Summary:Load balance in P2P storage system will affect availability greatly. Two aspects should be considered in keeping balance: balance in peer space and balance in data replica among peers. This paper focuses on achieving balance in peer space. Peers are categorized by periodicity of availability, and long term peers are organized into virtual balanced binary tree which is improved from P-Grid. Character of P-Grid is analyzed and balanced algorithm is given for peers encounter and departure. This system can bring great advantages of scalability, decentralized control and reliability and provide new solution for increasing demands on data storage.
