ETSI - TR 102 927

Speech and multimedia Transmission Quality (STQ); Packet Loss Concealment (PLC) performance measurement setup for home networks

active, Most Current
Organization: ETSI
Publication Date: 1 November 2010
Status: active
Page Count: 17
scope:

The present document describes the principles of performance measurement of PLC mechanisms for Voice over IP, based on a simulation of mastered degradations (IP packet loss with growing importance), assessment of QoS (through MOS-LQO scores) at the output of PLC. It defines the measurement setup needed and describes the detailed analysis of its behaviour.

The present document presents a detailed and practical description of the corresponding test setup and procedure.

Annex A provides examples of results of measurements done according to the test procedure defined in the present document.
