Surveillance data network transition strategy

The expanded need for surveillance data is impossible to realize if the current point-to-point approach continues. The ideal solution is a situation where each sensor publishes data on a broad network and each user subscribes to data based on some established rules. This is the surveillance data network (SDN) concept. It offers the benefit of better efficiency, higher scalability, more flexibility and potentially new ways for cross-agency information intelligence sharing. Unfortunately, none of the agencies with existing command and control nodes can afford, financially or in terms of performing their missions to shut down the current system and switch over to a new one. This paper presents strategy and a roadmap to transition from today´s situation to the future SDN.
