What are link weights and how are they computed?
The link weights in connectivity mode are computed from full routing tables from RouteViews and RIPE-RIS. The numbers shown in the “Weight” columns are the number of routes averaged over 126 monitors with temporal average (0.8 * past_value + 0.2 * current_value). For link A-B Cyclops shows the number of routes that reach B from A (from), as well as the number of routes that reach A from B (to). The former value indicates how the Cyclops eye is reaching the rest of the Internet, while the latter indicates how the rest of the Internet is reaching the Cyclops eye.
