No network left behind: How network as a sensor delivers full network visibility
The mission must continue – and that means networks must be up and secure, no matter what. Now more than ever before, networks can provide visibility at every layer, so agencies can identify and respond to service interruptions immediately. Network-as-a-sensor capabilities enable this deep awareness.
By Steve Alexander and George Holland – When we talk about network as a sensor, it’s really about using the network as a mechanism to pull information about the customer experience. It’s a way to provide deep insights about the current and future performance of the network without needing a set of external devices to gather that data. In the past, this would have required bolting lots of sensors and firewalls and other products onto the network. Now agencies can gain insights with the network elements themselves.
Networks continue to rapidly grow in capacity, complexity, and flexibility, and the historical approach of bolting sensors on doesn’t really scale in terms of cost or manpower to operate the network. And it’s hard for bolted-on equipment to evolve with the network. Having sensor capabilities built-in means, the network itself can grow and provide the visibility necessary to support future mission capabilities in government.
Network as a sensor helps agencies address several priorities. First, they want to converge the layers of the network for better visibility, all the way down to the fiber.
Second, agencies are taking cybersecurity much, much more seriously. To Steve’s point, they’re just not looking to strap on some firewalls or intrusion detection prevention systems. They want the network to actually become a sensor and eventually an enforcer that is capable of protecting itself. more>

Over the next two years, the Defense Department will launch the first of hundreds of small satellites populating Low Earth Orbit, that can directly link to and benefit from the megaconstellations being built by SpaceX, Telesat, and other commercial vendors. Its level of success could radically change the military satellite industry.
By Vivienne Machi – U.S. Defense Department agencies are working with a who’s-who of military contractors, commercial satellite operators, and technology companies to finally demonstrate the feasibility of a proliferated constellation of satellites in Low-Earth Orbit (LEO).
The concept of using hundreds of small satellites spread out across that orbit to perform communications, missile warning, and other military missions, has been discussed for years. But it was often dismissed as a pipe dream due to the immense launch cost projections, and size, weight, and power constraints required to operate and maintain capabilities in Low-Earth Orbit.
But thanks to recent, rapid technology advancements in the commercial sector, that pipe dream is now becoming a reality, and many former skeptics have come along for the ride.
When Derek Tournear was a program manager for the Defense Advanced Research Projects Agency (DARPA) 10 to 15 years ago, he was unconvinced that small satellites operating together in a constellation could be powerful enough to enable those crucial missions.
Now, as the director of the DoD’s Space Development Agency (SDA), Tournear is a little over a year away from launching the initial satellites for the U.S. military’s first proliferated LEO constellation, which will eventually include layers of hundreds of sensors. “I’ve completely changed my tune,” he says. more>
