An important feature of joint operations at sea under the conditions of modern network is The battlefield environment more complex, ever-changing battlefield situation fighters fleeting nonlinear characteristics of the war are more prominent. Swelling of battlefield information requirements and increasingly complex the sea battlefield electromagnetic environment, limited wireless bandwidth and transmission quality has become a sensor, command and control system, weapons and combat effectiveness play direct constraints. The right information at the right time to send to the appropriate operational node, must address information raster environment of the information distribution problem, research under the tension of the transmission bandwidth resource efficient information distribution technology. The research is the General Armament Department, \In support of maritime information grid technology - grid technology, describes the grid definition and characteristics, in-depth study of the grid five hourglass structure and open mesh OGSA specification, information distribution technology at home and abroad the status quo. Current battlefield information distribution technology exists to do the analysis, the classified information on the battlefield, and made a detailed description of the distributed information, and then the function of the distribution system based on the above basis, six needs analysis : load balancing, dynamic reorganization and invulnerability restructuring, information retrieval, system status monitoring, distributing quality requirements, distributing performance requirements. In the comprehensive consideration to the above functions demand for battlefield information distribution characteristics, proposed application \able to make information exchange, both in time, space and control flow are completely decoupled, asynchronous communication is more suitable under conditions of limited network bandwidth. \three matching algorithm are compared. Finally, in the analysis of these theories, the design of an information distribution at sea demonstration system, gives the system structure diagram and information distribution center network diagram, presentation of the specific module. Laid the foundation for the subsequent maritime information distribution system.
