ITU-T E.802 (2007) Amd. 1 (03/2017)

New Annex A on guidelines on selection of representative samples

Amendment 1 to Recommendation ITU-T E.802 incorporates Annex A, which provides guidance on the selection of representative samples in the measurement of QoS parameters. Recommendation ITU-T E.802 had opted not to give this guidance because “the selection of representative samples is a process that is heavily influenced by specific technical and operational conditions of the measurement task.” (see clause 8.5). Annex A therefore provides guidance that takes into account these technical (statistical) and operational (practical QoS data collection) conditions by proposing a simple random sampling methodology.

This amendment also adds Appendices IV and V with additional information on the implementation of the sampling algorithm included in Annex A, and on the use of sample-based QoS parameters.
