With the combat information and network users increased dramatically , especially the large amount of data streaming content and dynamic content increases , common operational picture and streaming media information , on the one hand, more intuitive, realistic battlefield , on the other hand , more exacerbated the demand for network bandwidth , network load is constantly increasing . The starting point of the information distribution strategy is to improve the ability of the entire information distributing system . Thesis focuses on how to effectively achieve the battlefield all kinds of information sharing and flow , based on application layer multicast protocol information distribution strategy , and focus on study three aspects of which the key issues from the routing of information , information resources , organization and basic information services . Goal is to provide an efficient, rapid information distribution mechanism in a battlefield environment . Related work can be summarized as follows : (1) an in-depth study based on CAN, Bayeux, Scribe P2P application layer multicast , combined with the distribution requirements of battlefield information , a battlefield information distribution model ( Hierarchical Scribe ) . (2) comparative analysis Pull , Push and Smart - Pull ( Smart Push ) three kinds of information distribution strategy , and on this basis, based on to propose a more effective information distribution strategy , design the corresponding routing algorithm and packet format , data distribution algorithm . ( 3) Design and Implementation of a the information distributing authentication system based on the thesis , the design of the architecture , defines the message format and message processing system interaction , information distribution processing application module , to improve the underlying communication protocol . Finally, the system is given secondary development interface .
