| Along with the high speed development of information technology, whether we can obtain the information advantage becomes the key factor which can determine the result of the war, and the crucial facet to get the information advantage is that different units can communicate with each other effectively. The war field space in the future is special, in which the information has some characteristics, such as its higher density, bigger quantity, more types and forms, and more complex relations between each other. In this situation, information sharing is very difficult to achieve.The circumstance in the war field changes fast, so the military departments usually encounter different, dynamic, abrupt mission. With the appearance of the joint operations, the constitution of a campaign plan needs resources from many different departments,and the departments in the battlefield environment communicate with each other frequently, so we must offer a method which can insure that multifarious resources in the war field can be seen, understood and used. With the measure, we can provide the information foundation for the joint operations, and the joint circumstance of the war field space will be formed.In the background and based on the characteristic of the information resource in the war field, we use the directory service technology to improve the ability of information retrieve.This paper gives a comparatively integrated method of programming and designing the directory service system, and we designed the data model based on the special characteristic of the resources in the war field space, through the model, we can have a uniform structure for the resources. In the paper we proposed a distributed means to deploy the directory, and developed the update and research method based on it. Simulation experiments demonstrate that the method is efficiently.At last, we make a summary of our studies, and give some opinions for the future research. |
