Research and application of comet technology in public logistics information platform

With the development of our economy and the strengthened foreign communication, logistics industry faces more and more intensive competition while having very rapidly development. It is necessary to build the public logistics information platform(PLIP) to meet forth stricter requirements for the instantaneity and accuracy of logistics information. But most Web-based systems are based on the original Web or Ajax model which is limited by web´s request/response architecture, and clients need to send requests frequently to refresh server-side data with low efficiency, high bandwidth consumption and bad user experience. In order to overcome these weaknesses on data synchronization and real-time, we apply pushlet, an open source Comet framework, to the PLIP in this paper, and implement real-time logistics data push in the “server push” way. The result shows that it can ensure timeliness and correctness of information, and in the same time reduce the consumption of network bandwidth. The PLIP using Comet will improve the management efficiency, save the logistics costs, and promote resource integration in logistics industry.
