Abstract :
IP networks and multimedia real-time applications running on them have experienced an amazing development, but require plenty of network resources for a correct performance. The evaluation of quality of service in Internet accesses for multimedia applications (EQoSIM) system provides an easy way of measuring network performance. Its capacity estimation module needs a special processing to avoid calculation errors due to clock granularity. This paper presents different methods to deal with clock granularity and shows experimental results using a commercial ADSL Internet access.
