Data update consistency control based on P2P network in product collaborative design environment

In order to meet the needs of product collaborative design, a method of data update consistency control was presented based on Peer-to-Peer (P2P) network technology. The data consistency management mode was established in P2P collaborative design environment, and method of data update control was analyzed among design peers. Through constructing collaborative mode of P2P groups, we realized control mechanism of data update consistency on the basis of the design constraint sets. The proposed approach offered effectively technical support for dynamic data management of design process in distributed collaborative environment.
