Title : Model Based Bulk Performance Metrics

Filename : draft-ietf-ippm-model-based-metrics-03.txt
Pages : 43

Abstract:
We introduce a new class of model based metrics designed to determine
if an end-to-end Internet path can meet predefined transport
performance targets by applying a suite of IP diagnostic tests to
successive subpaths. The subpath-at-a-time tests can be robustly
applied to key infrastructure, such as interconnects, to accurately
detect if it will prevent the full end-to-end paths that traverse it
from meeting the specified target performance.
Each IP diagnostic test consists of a precomputed traffic pattern and
a statistical criteria for evaluating packet delivery. The traffic
patterns are precomputed to mimic TCP or other transport protocol
over a long path but are independent of the actual details of the
subpath under test. Likewise the success criteria depends on the
target performance for the long path and not the details of the
subpath. This makes the measurements open loop, which introduces
several important new properties and eliminates most of the
difficulties encountered by traditional bulk transport metrics.
This document does not define diagnostic tests, but provides a
framework for designing suites of diagnostics tests that are tailored
the confirming the target performance.
