On Evolution of C2 Network Topology

C2 is shifting from traditional hierarchical organization structure towards more collaborative and adaptive endeavors, with system of systems being rebuilt on a foundation that incorporates agility, focus, and convergence, namely networked in both the theoretical and the operational front. At present, flexible, secure and efficient C2 network topology is one of the fundamental issues for C2 study. Due to the openness and dynamic nature resulting from multi-threat and diversity of mission, and also influenced by factors like link situation, information flow, command and cooperative relationship which interact with each other, the specification, modeling, resolution and building of C2 network topology stand in our research way. In addition, circumstances and mission requirements are in a state of flux, topology reconstruction seems to be built in and it then becomes another monkey on the back. Under complex networked environment, statistic based topology model is of significance for constructing and maintaining an expected topology. This paper, after summarizing the topology requirements of C2 networks in the eye of agility, security and performance, examines the existing typical topology models and points out the deficiencies against the requirements. Finally, existing problems, open issues are analyzed and research approaches are proposed for reference.
