A method for near real time quality analysis consistent with certain embodiments passively samples packets ( 616 ) from a stream of Internet Protocol (IP) packets that represent a communication session between a pair of end points carrying signals being transmitted over a transmission path in an IP network, and determines ( 620 ) in near real time at least two metrics from the sampled packets for the communication session. The at least two metrics include at least one metric that measures a quantity of lost packets, and at least one metric that measures a characteristic of packet timing. The method further involves calculating ( 632 ) a quality score in near real time using a quality formula that combines the at least two metrics. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
