Abstract:
We introduce a new class of model based metrics designed to determine
if a long network path can meet predefined end-to-end application
performance targets by applying a suite of IP diagnostic tests to
successive subpaths. The subpath at a time tests are designed to
exclude all known conditions which might prevent the full end-to-end
path from meeting the user's target application performance.
This approach makes it possible to to determine the IP performance
requirements needed to support the desired end-to-end TCP
performance. The IP metrics are based on traffic patterns that mimic
TCP or other transport protocol but are precomputed independently of
the actual behavior of the transport protocol over the subpath under
test. This makes the measurements open loop, eliminating nearly all
of the difficulties encountered by traditional bulk transport
metrics, which fundamentally depend on congestion control equilibrium
behavior.
A natural consequence of this methodology is verifiable network
measurement: measurements from any given vantage point can be
verified by repeating them from other vantage points.
