Accedian Networks has launched multicast service testing to assure the quality of service of real-time, packet-based broadcast and communications applications. The multicast Performance Assurance Agent (PAA) for EtherNID and MetroNID demarcation units measures packet transmission performance and server responsiveness to monitor large-scale IPTV, VoIP conferencing, telepresence and mobile TV media streaming applications.
The solution continuously measures microsecond-resolution one-way delay and jitter, frame loss and continuity for point-to-point, hub-and-spoke and full-mesh services. The new multicast PAA extends these capabilities to monitor broadcast-style services over wireless and wireline networks, simultaneously testing from the multicast source (head-end) to each cell site or subscribed enterprise location independently.
