What this shows is a “ping” from a computer in Southampton going all the way to Glen feshie (last part via satellite link), through our “border router”, across to a node via the low power radio. It took around a second for the reply to get back to Southampton. (The IPv6 addresses have been blurred to prevent attacks).

For techies: the interval is set to 10s to prevent overloading the low power network and the packet size is set to 25 so it is small (6LowPAN prefers small packets)
