Mu Dynamics Tackling VoIP, IPTV and IMS Architecture Challenges

By Tim Gray, TMCnet Web Editor


While Service Assurance of next-generation IP services — whether dealing with reliability, availability and security of services such as VoIP, IPTV (News - Alert) and IMS – is widely considered the most critical issues facing service providers and vendors, it falls to next generation IP services to provide a high quality of experience in order to compete.
 
In fact, as the demand for these high-value services grows, and given the inherent complexity and diversity of next generation networks, a service quality issue has arisen.
 
According to InStat, worldwide cable telephony service revenues are on track to reach $12.6 billion in 2008, up from $10.7 billion in 2007. Total worldwide cable telephony subscribers are projected to reach 37 million by the end of 2008, and rise to over 64 million by 2012.
 
At issue for most companies is the high cost of downtime. And achieving the service levels that customers expect in the long term means minimizing downtime.
There are two types of network downtime:  degradation, when a latency-sensitive service is slower than usual, perhaps even useless outright outage, when a service is unavailable.
 
Matt Graff, defense account manager of British Telecom, said Mu Dynamics allowed his company to baseline the reliability of every vendor and potential system prior to making a purchase decision— proactively detecting any problems that could lead to disruption or downtime in our production networks.
 
The California-based company provides network operators and vendors network application testing for converged services.
 
“The automated analysis performed by the Mu-4000 is far more comprehensive than any manual process or point product solution we have evaluated to date, and this will be critical to BT (News - Alert) as we implement our next generation of real-time network infrastructure and services,” said Graff.
 
BT is expected to now use Mu-4000 Service Analyzer to support the evaluation and testing of proposed services on the U.K.’s Defense Fixed Telecommunications Service (DFTS) network.

The Mu Service Analyzer is purpose-built to satisfy increasing complexities and enables operators to accelerate the rollout of new and enhanced VoIP, IPTV and IMS architecture-based services, while ensuring any NGN service delivers the high levels of availability and reliability needed to maintain customer satisfaction and reduce churn.
 
Essentially, there are two types of downtime that often results: degradation, when a latency-sensitive service is slower than usual and outright outage, when a service is unavailable.
 
These costs include:
  • Lost revenue from service downtime
  • Customer churn
  • Avoidable support costs
  • Service level agreement (SLA) related penalties
  • Decreased average revenue per user (ARPU)
In order to address these challenges growing number of service providers are turning to Mu’s service assurance solution. The Mu solution – including service-level traffic variations – is designed to eliminate quality issues including system crashes, distributed denial of service attacks and more subtle issues like response-time latency and CPU utilization spikes.
