ITU-T Question 4/4 has finalized its work on Draft new Recommendation O.211,
â€œTest and measurement equipment to perform tests at the IP layerâ€?, which
specifies test packets to assess the packet transfer performance in IP-based
networks. This draft recommendation has been consented during the September
2005 meeting of SG4. Please find it attached. Each test packet contains a
standardized data structure, the IP Performance Measurement Signature (IPPMS),
which includes definitions for timestamps, sequence numbers, and error check
procedures as well as information to identify the measure and the metrics.
Metrics correspond to Y.1540 parameters and those registered in the
IANA-IPPM-METRICS-REGISTRY. The IPPMS definitions are not restricted to
IP-Layer performance measurements, but can be re-used for other frame-or packet
based networks. Question 4/4 is happy to bring this work to your attention and
hope it is useful for your work in this area. Comments are of course welcome.
