Abstract

Packet delivery statistics are derived from a User Datagram Protocol (UDP) stream simulating a service level provided by a Voice over Internet Protocol (VoIP) network and transmitted across the VoIP network at a first pre-defined interval. The derived packet delivery statistics are processed at a second pre-defined interval to generate network performance statistics for the VoIP network, where the second pre-defined interval is substantially larger than the first pre-defined interval.
