How fast can Cyclops react and alert me of anomalous events?
Cyclops can react as fast as a few seconds in case the event is detected in BGPmon real-time feeds. For other feeds, it tyipically takes anytime between 5 and 15 minutes. The data available from the left menu (connectivity, prefixes, anomalies) is tipically refreshed every 1 to 2 hours. • What about ipv6? Cyclops supports ipv6 by default. • What about 4-byte ASNs? Cyclops currently supports 4-byte ASNs using dotted decimal notation. We are planning to change to ASPLAIN as soon as BGP feeds have them. • 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 ey
