Accedian Networks has introduced the multicast Performance Assurance Agent (PAA) for EtherNID and MetroNID demarcation units, which measures packet transmission performance and server responsiveness to monitor large-scale IPTV, VoIP conferencing, telepresence and mobile TV media streaming applications.

Accedian Network’s PAA technology assures the Quality of Service (QoS) of real-time, packet-based broadcast and communications applications, and the technology is used by service providers to monitor demanding business services, as well as 3G and 4G 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 company said, and 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 headend to each cell site or subscribed enterprise location independently.

Internet Group Management Protocol (IGMP) support provides measurements to help validate video channel change time and conferencing join/leave delay. And the company said that its EchoVault SLA EMS platform – which is more detailed than SNMP-based monitoring systems – centralizes results from thousands of endpoints to provide per-second QoS reporting, graphing, fault management and operational support system (OSS) integration in real-time.

“Accedian Networks’ innovative Packet Performance Assurance solutions have enabled service providers to establish high-performance Ethernet and IP services backed by demanding Service Level Agreements,” said Patrick Ostiguy, Accedian Networks’ founding president and CEO. “These providers are now leveraging their assured networks to deliver value-added, real-time applications, including telepresence, VoIP conferencing and multicast video distribution. The new multicast PAA reflects our longstanding commitment to helping our customers deliver and maintain best-in-class QoS as they scale into new markets and applications."
