Performance-Driven Internet Path Selection
Maria D. Apostolaki, Ankit Singla, Laurent Vanbever · 2021
Internet routing can often be sub-optimal, with the chosen routes providing worse performance than other available policy-compliant routes. This stems from the lack of visibility into route performance at the network layer. While this is an old problem, we argue that recent advances in programmable hardware finally open up the possibility of performance-aware routing in a deployable, BGP-compatible manner.
