At this week’s global GMI 2008 event, Spirent Communications provided solutions for IMS-based IPTV service integration and interoperability tests.
Spirent has contributed more than $1.6 million in test equipment and 800 hours of professional services expertise this year alone. By supporting several test scenarios, the company is demonstrating key testing functionality over an IMS architecture including end-to-end Quality of Service (QoS) of VoIP calls, performance of emergency location-based applications such as E911 services, performance of the mobile core network, and quality of IMS-based and non-IMS based IPTV delivery. In addition, Spirent was responsible for the development and implementation of test cases for evaluating video quality and related metrics, and IP network impairments based on ITU-T G.1050-2007.
“Delivering high-quality IPTV services over an IMS architecture is particularly demanding because it is technically complex, occupies a significant amount of network bandwidth and even small amounts of network impairments can significantly affect the end-user experience,” said Jack Douglass, director of video technologies at Spirent Communications. “IMS-based IPTV must support both broadcast and on-demand TV services with the same quality of experience consumers currently have with traditional cable and satellite services. Our expertise in video and IPTV testing, coupled with its leadership in the IMS space, makes Spirent a perfect fit for this GMI event.”
Spirent says it provides companies like Cisco, Brocade and Alcatel-Lucent with solutions to help ensure that the multiplay networks and multitechnology platforms of tomorrow deliver the Quality of Experience (QoE) which service providers are demanding today. The company believes testing the converged network is a strategic imperative for service providers and network equipment manufacturers to reduce churn and increase revenue potential.
