On Reachability of Autonomous Systems Based on Announcements Changes -Edición Única

In this work data obtained from interdomain routing protocol (IDR) is used to obtain statistical analysis of Autonomous Systems using the protocol. With the statistical description we observe the reachability of three AS belonging to the Internet core and its three most active links. We also calculate the updates and withdrawals to monitor the changes observed in the three AS from the interdomain protocol. This monitoring led us to find a ratio around 1 for updates and withdrawals, this could be taken into consideration for detecting anomalies in the interdomain routing protocol. The creation of solutions for such anomalies is out of the scope of this work
