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).
