A distributed data service platform is established mainly to solve the problem of data sharing among several data centers in narrowband WAN environment, provide continuously reliable and position-independent data services for the users and realize the objective of transmitting right information to right customer in right way (3R). The multi-center data service platform optimizes data consistency algorithm against WAN features (small bandwidth and long delay) based on network technology, distributed technology and parallel computing technology, using peer-to-peer cluster-based network system framework, combined with “Cloud storage” framework features, and provides such characteristic functions as strategy-based oriented sharing, priority control and network flow control as well as capabilities of synchronously sharing file data and database data facing overall situation and subject to unified management. The global distributed data redundancy storage also provides the users with new data backup for disasters; intelligent troubleshooting and inter-node high self-fusion features can provide efficient data fault-tolerant and data service recovery capabilities in case of fault of network or other hardware as well as continuous and non-stop data services for the users. System joint debugging in actual narrowband WAN operation environment shows that the system can fully meet the engineering demands in synchronous data sharing, system stability etc., and has good promoting value.
