SUNNYVALE, California, October 28 /PRNewswire/ --

    - Next-Generation Networks Benchmarked with Industry Leading Test
Solutions



    Spirent Communications (LSE: SPT) today announced its participation at
GMI 2008, a global MultiService Forum (MSF) interoperability event, with
solutions for IMS-based IPTV service integration and interoperability tests.
As a global provider of performance analysis and service management
solutions, Spirent has been supporting GMI events since their inception in
2002. This year's emphasis on IMS-based IPTV service gives Spirent an
opportunity to showcase its extensive experience in both IPTV and IMS
testing.

    Spirent is powering the deployment and delivery of next-generation
networks and is aligned with GMI's mission to "make Next Generation Networks
work". Participating at three of GMI 2008's host locations - the labs of
Verizon, NCS and BT/Vodafone - Spirent has contributed more than US$1.6 
million in test equipment and 800 hours of professional services expertise. 
By supporting several test scenarios, Spirent 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 is providing award winning test solutions to support GMI's Next
Generation Network (NGN) interoperability efforts. Spirent TestCenter(TM) -
an integrated test platform that accelerates conformance, functional and
performance testing for converged networks - with its Video Quality Analyzer
- allows for the assessment of over 100 metrics related to delivering high
quality IPTV. Spirent GEM helps emulate 'real-world' IPTV network impairments
based on ITU-T Recommendation G.1050-2007 and ANSI TIA-921A. Spirent Abacus
is being used for IMS VoIP testing and emergency call services, while Spirent
Avalanche is facilitating IPTV multicast video and Web services testing and
Spirent Landslide is testing GSM/UMTS core networks.


    Communications industry leaders such as Cisco, Brocade, Alcatel-Lucent
and others, who are advancing the next-generation network evolution, depend
on multi-functional, comprehensive solutions from Spirent to help ensure that
the multi-play networks and multi-technology platforms of tomorrow deliver
the Quality of Experience (QoE) which service providers are demanding today.
Testing the converged network is a strategic imperative for service providers
and network equipment manufacturers to reduce churn and increase revenue
potential.
