Abstract:
We introduce a new class of model based metrics designed to determine
if a long path can meet predefined end-to-end application performance
targets. This is done by section-by-section testing -- by applying a
suite of single property tests to successive sections of a long path.
In many cases these single property tests are based on existing IPPM
metrics, with the addition of success and validity criteria. The
sub-path at a time tests are designed to facilitate IP providers
eliminating all known conditions that might prevent the full end-to-
end path from meeting the users target 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 but are precomputed independently of the actual behavior of TCP
over the sub-path under test. This makes the measurements open loop,
eliminating nearly all of the difficulties encountered by traditional
bulk transport metrics, which rely on congestion control equilibrium
behavior.
A natural consequence of this methodology is verifiable network
measurement: measurements from any given vantage point are repeatable
from other vantage points.
