A performance evaluation of BGP-based traffic engineering
Bruno Quoitin, Cristel Pelsser, Olivier Bonaventure and Steve Uhlig
Many Internet Service Providers tune the configuration of the Border Gateway
Protocol on their routers to control their traffic. Content providers often
need to control their outgoing traffic while access providers need to control
their incoming traffic. We show, by means of measurements and simulations,
that controlling the flow of the incoming interdomain traffic is a difficult
problem. For this purpose, we first rely on detailed measurements to show
the limitations of AS-Path prepending. Then, we show by using large-scale
simulations that the difficulty of controlling the flow of the incoming
traffic lies in the difficulty of predicting which BGP route will be selected
by distant ASes.
