Multi Data Link integration technique is a highly useful approach to enhancing the combat effectiveness. In this paper, by presenting the most recently current work of Multi Data Link integration technique of the US Army, we analyze the corresponding technical requirement of the technique first, and then we propose a framework which is based on the interface, data, information and services. This framework can be used to effectively address the problem of multi-type data link framework integration and the problem of how to apply this technique into real applications, and we also show the scalability and openness of the proposed framework. Finally, we discuss the future work of Multi Data Link integration technique.
