Notes:


This figure is based on a study of all the interdomain traffic of three distinct ISPs at different periods of time. The trace was collected during one week for BELNET, the Belgian Research ISP, five days for YUCOM, a dialup ISP based in Belgium and one day for PSC, a gigapop in the US. This figure is analyzed in :

A detailed analysis of the characteristics of interdomain traffic based on a stub ISP may be found in :

A similar result concerning the traffic distribution was obtained by studying the traffic of a tier-1 ISP, see
