Abstract:	The paper presents the designing of a software tool for real-time measurement of the following quality of service parameters: one-way delay, average one-way delay, IP packet delay variation and average IP packet delay variation. The solution is an improved version of OreNETa (One-way delay REaltime NETwork Analyzer), by optimizing the traffic between the meter and the analyzer. When a new flow is detected, the meter assemblies a flow descriptor and sends it to the analyzer. Following the flow recording, it will announce the meter to send a shorter message, called header, for all the packets belonging to the newly registered flow.
