Which one should I pick?

Inbound Traffic Engineering (ITE) is an essential part of the operation of an Autonomous System (AS). By properly announcing its prefixes, an AS can reduce transit costs, mitigate congestion, and improve its subscribers' overall experience. By interviewing network operators, we learned that operators usually rely on their expertise and in a trial and error approach for selecting one technique for ITE (i.e., AS-Path Prepending, selective announcements). We also learned that sometimes the effect of applying a particular technique could be "stronger" than the necessary for a given situation. Intrigued by such answers and the lack of systematic comparison of the existing ITE techniques in the literature, in this work, we propose an investigation to compare the effectiveness of the different ITE techniques in the wild.
