Purpose: For information 
Body: ITU-T Question 4/4 has finalized its work on Draft new Recommendation O.211, “Test and measurement equipment to perform tests at the IP layer”, 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.
