There are more different architectures of tactical internet because of more different network equipments which bring a lot of difficult to discovery topology in tactical internet. To realize topology discovery on tactical internet which own special architecture and communication model because of the router-switch which was the unique key equipment of tactical internet made by special institute, a distributed topology discovery method was proposed based on Agent. It depended on cooperation of two topology discoveries: topology discovery in management domain and topology discovery in whole network. Through rational assigning tasks of the two topology discoveries, occupation of radio bandwidth on topology discovery would be reduced more largely. Collecting topology data in time and using radio bandwidth more rational would be realized by adjusting process priority of topology discovery in whole network with manual regulation and self-adaptation regulation. Then two algorithms of topology discovery in management domain and in whole network firstly were presented. The data saving structure of topology discovery in management domain was designed in detail and these data would be sent to network management centre from Agent.]]>Kakakhel, A.K. and N.
