Measuring Multipath Routing in the Internet

Tools to measure Internet properties usually assume the existence of just one single path from a source to a destination. However, load-balancing capabilities, which create multiple active paths between two end-hosts, are available in most contemporary routers. This paper extends Paris trace-route and proposes an extensive characterization of multipath routing in the Internet. The authors use Paris trace-route from RON and PlanetLab nodes to collect various datasets in 2007 and 2009. Their results show that the traditional concept of a single network path between hosts no longer holds. For instance, 39% of the source - destination pairs in their 2007 traces traverses a load balancer. This fraction increases to 72% if they consider the paths between a source and a destination network.
