Except that videoconferencing is just the victim of the problem, and
the problem is bursty bandwidth not latency. In fact, the back-and-
forth of conversation is actually surprisingly decent for satellite.
Not as much "talking over" as I would have suspected.
But put the victim application aside, the real data is in the iperf3
results I posted, demonstrating how bursty the throughput is. The
problem with that of course is that the "lowest" bandwidth "valleys"
becomes the "constant bandwidth" that the codec uses rather than the
average -- which of course cannot be used for real-time VC.
