The subpath-at-a-time tests can be robustly applied to critical infrastructure, such as network interconnections or even individual devices, to accurately detect if any part of the infrastructure will prevent paths traversing it from meeting the Target Transport Performance. Model Based Metrics rely on peer-reviewed mathematical models to specify a Targeted Suite of IP Diagnostic tests, designed to assess whether common transport protocols can be expected to meet a predetermined Target Transport Performance over an Internet path. For Bulk Transport Capacity IP diagnostics are built using test streams and statistical criteria for evaluating the packet transfer that mimic TCP over the complete path. The temporal structure of the test stream (bursts, etc) mimic TCP or other transport protocol carrying bulk data over a long path. However they are constructed to be independent of the details of the subpath under test, end systems or applications. Likewise the success criteria evaluates the packet transfer statistics of the subpath against criteria determined by protocol performance models applied to the Target Transport Performance of the complete path. The success criteria also does not depend on the details of the subpath, end systems or application. Model Based Metrics exhibit several important new properties not present in other Bulk Transport Capacity Metrics, including the ability to reason about concatenated or overlapping subpaths. The results are vantage independent which is critical for supporting independent validation of tests by comparing results from multiple measurement points. This document provides a framework for designing suites of IP diagnostic tests that are tailored to confirming that infrastructure can meet the predetermined Target Transport Performance. It does not fully specify the IP diagnostics tests needed to assure any specific target performance.}, }
