We study the interdomain traffic as seen by two non-transit ISP, based on a week long trace covering all the interdomain links of these ISP. Our analysis considers the relationships between the interdomain traffic and the interdomain topology. We discuss the day-to-day stability of the interdomain traffic to evaluate the feasibility of interdomain traffic engineering. Then, we study the variability of the interdomain flows for several aggregation levels (prefix, AS and sink tree) and with respect to the interdomain topology seen by BGP. We then discuss the implications of these traffic characteristics on traffic engineering.
