Abstract

As a stateless distributed component, web service could not transfer large data simply and safely under confine of network communication. This problem affects service centric system's performance for data concentrated applications. To address the issue, LDT4WS is introduced to enhance web service to transfer large data. In LDT4WS, large data is converted into binary and divided into smaller packs by sender. Receiver creates context for packs' relationship by which packs could be organized orderly and integrated. In data transferring, the network failure would be checked and only the failed packs would be transferred. Upon LDT4WS, a data exchange platform is built for CAE's SPON. In the system, large data are transferred safely by web service.
