Summary of Results

From Sections 4.1 and 4.2, we observe that the circuitousness of a route depends on both the geographic and network location of the end-hosts. In many cases, the trends we observe in the distance ratio are consistent with our intuition. A large value of the distance ratio enables us to automatically flag paths that are highly circuitous, possibly (though not necessarily) because of routing anomalies. Finally, we show that the minimum delay between end-hosts and the linearized distance of their path are strongly correlated. This relationship indicates that the circuitousness of a route does have an effect on the delay observed along the route (though this does not completely dictate the performance along the route).
