Bulk transfer capacity (BTC) was measured in kilobits per second (Kbps) or megabits per second (Mbps), as indicated.
Round-trip time (RTT), as reported by Ping.
Number of hops, or steps, in the most frequently used Internet pathway (route) between the NLM and the remote location, as reported by Traceroute. A “plus” sign (+) indicates that the actual value is greater than or equal to the value shown.
Percentage of times an observed route (as returned by Traceroute) from the NLM to the indicated location was the same as the immediately preceding observed route to the same location. An “approximately” sign (∼) indicates that the value shown is estimated.
NA indicates data that were not available or could not be measured (e.g., because of a firewall).
