Accedian's Multicast Service Testing to Assure QoS

Accedian Networks has announced multicast service testing to assure the QoS of real-time, packet-based broadcast and communications applications. It’s supposed to precisely measure packet transmission performance and server responsiveness. The purpose is to monitor large-scale IPTV, VoIP conferencing, telepresence and mobile TV media streaming applications.

Accedian Networks’ PAA technology is widely used to monitor demanding business services and 3G and 4G (WiMAX / LTE) wireless backhaul 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, with the ability to simultaneously test from the multicast source (head-end) to each cell site or subscribed enterprise location independently.

In addition to monitoring unidirectional streaming performance, Internet Group Management Protocol support provides measurements to help validate video channel change time and conferencing join / leave delay.
