Present-day IP transport platforms being what they are, it will never be possible to rule out conflicts between the\navailable services. The logical consequence of this assertion is the inevitable conclusion that the quality of service\n(QoS) must always be quantifiable no matter what. This paper focuses on one method to determine QoS. It defines\nan innovative, simple model that can evaluate the QoS of MP3-coded voice data transported through an IP environment.\nIt describes tests of the model�s practicability that were conducted in a comprehensive comparison study. The so-called\nMP3 Model is one of a number of parameter-based measuring techniques and delivers results that come very close to\nthe corresponding perceptual evaluation of speech quality (PESQ) curves. This is one of the features that make this new\nQoS measuring method so attractive.
