The network topology involves a series of conditions: the type of the cable used, the route of the cable, the elements of virtualisation, the connections of the network assets, the layout of the encryption elements. The network topology can determine the way the computers in the network communicate. In the domain of local networks, in the author's opinion, there are several possible topologies, out of which only three are widespread: line, ring and star. The mission networks should facilitate the access to the services provided by the infrastructure and ISTAR (Intelligence, Surveillance, Target Acquisition and Reconnaissance) in the deployment area.
