Research And Implementation Of Transmission Service Based On Globus Grid

Grid connect so many resouces which are far-ranging distributing geographically to a logical whole, (including compute resource, storage resource, bandwidth resource, software resource,data resource,information resource and knowledge resource)just like a super computer,offering incorporate information and application service.The grid research is from America,review these grid projects which belong to those related organizations, the most famous grid research plan is the Globus,it strives to implement compute grid structure, giving universal,reliable and consistent accessing to high-powered remote compute resource.The data transfer is at an advantage status in all the grid services, all the storage and compute need the support of transfer. Grid circumstance need a express,secure, effective and reliable transfer mechanism.Grid projects all-around consider the protocol and technology which are available at present and some prototype bases which already come true, make certain use the FTP protocol as foundation and extend the FTP protocol, add some essential function of grid compute, the GridFTP protocol brings forward consequently. Depending on the FTP protocol, the GridFTP protocol and tools base on it provide some other characters for grid data transfer, such as third-party transfer, parallel transfer and tripped transfer and so on.The research emphases in this paper is the grid data transfer mechanism based on Globus, from the concept of GridFTP protocol,principle,transfer function, security and new transfer mechanism to realization, and then introduce the Globus Toolkit 4 platform, including architecture and related modules.At last we discuss the further integration of the GridFTP protocol and put forward some places that need be strengthened.
