Skitter RTT Plots

Below is a plot of RTT versus time for the path from caida.mae.net to nms1.San-Francisco.t3.ans.net. This plot is for a particularly sour day; a configuration change made nms1.San-Francisco.t3.ans.net unreachable from caida.mae.net from around 06:30 to 09:45 UTC. When the reachability returned, we see a change in the forward path for a few hours, and eventually a return to the original forward path. However, there's an obvious step function in the RTT after the period of unreachability, indicating a change for the worse in the reverse path.

See the CAIDA Resource Catalog view for this page to explore related objects.

Below the plot are some order statistics for the RTT measurements for each path, then a table showing each of the forward paths.
