Internet Bypass Routing
Based on our experience with DitTorrent, we identified that most of the time Internet bottleneck links may be bypassed by using a simple Interest Indirection Overlay. This enables the end-hosts to monitor and adapt to transient congestion and mis-configuration on the Internet. Our experience with PlanetLab nodes show that for developing-world countries, simply vectoring messages through intermediate nodes (and hence forcing routing paths at the overlay level) could lead to up to 300% improvement in packet latency and up to two fold improvement in available bandwidth.
Indirect routing has been used previously only to bypass failures on the Internet, circumventing the long convergence time of BGP. Our system, however, explores the role of indirection in overlay routing to improve Internet bandwidth and latency in the developing-world.
