Abstract
A network performance monitor and an associated method for monitoring the perceived transmission quality of a packetized multimedia signal encoded by a first codec are provided. The monitor includes a packet processor for performing real time direct counting of received and lost packets in the burst and gap states in the packet stream carrying the multimedia signal. A data processor is provided for determining packet loss distribution parameters using the burst and gap packet counters provided by the packet processor. In one aspect of the invention, the data processor is operative to compute an effective equipment impairment factor from the packet loss distribution parameters for a reference codec having known transmission impairments associated therewith, for assessing the network contribution to the perceived transmission quality of the multimedia signal.
