Can someone please clarify for me exactly what the aim is, however? I've been unable to find a cohesive problem statement anywhere. From what I've gathered, the idea seems to be to use the GPS timebase to provide a far better gauge of time-of-flight (I'm not a network engineer; I don't know what the real term would be) of a packet from one location on the internet to another than current methods can provide. I'm also thinking the idea is to distribute many of these so that the time-of-flight can be mapped and pinch points (created by filtering, throttling, or simply poor or undersized pipelines) can be spotted and fixed (by whatever means are appropriate for the given problem).
