Ascent Media Group Chooses NetQoS to Improve Network Performance; Media Services Company Uses NetQoS for Application Response Time and Traffic Analysis.

AUSTIN, Texas -- NetQoS(R) Inc. today announced that Ascent Media Group Inc., a wholly-owned subsidiary of Liberty Media Corporation (NYSE:L) (NYSE:LMC.B), is deploying SuperAgent(R) and ReporterAnalyzer(TM) to monitor and enhance application delivery over its wide area network (WAN) for more than 4,000 employees in 70 locations worldwide. NetQoS is the fastest-growing provider of performance analysis products and services for Global 2000 networks.

"NetQoS SuperAgent and ReporterAnalyzer are enabling us to better understand what is happening on our global network," said Danny Klone, director of IT for Ascent Media. "Rather than spending hours manually tracking down the source of a network or application problem with very little context, we now rely on these products to constantly monitor the traffic and automatically alert us to problems. As problems occur, we can easily call up a report and obtain real-time and historical information for troubleshooting."

Ascent, based in Santa Monica, Calif., chose NetQoS SuperAgent to monitor end-user response times for key applications and to troubleshoot problems -- without desktop or server agents. For instance, Ascent's enterprise resource planning (ERP) application for work order, billing, and scheduling drives its business of providing creative and technical media services to the media and entertainment industries. SuperAgent passively measures and analyzes application response times for all users of the ERP application, compares the response time against intelligent baselines, then automatically investigates the cause of problems as they occur.

SuperAgent isolates performance problems to the application, network, or server. For example, using SuperAgent with its large Citrix(R) server farm, Ascent can now determine whether an application performance problem is between a Citrix server and the user or a Citrix server and a database.

Ascent selected NetQoS ReporterAnalyzer to monitor hundreds of WAN interfaces and discover which applications are using bandwidth, who is using the bandwidth (which facilities and users), and when. By knowing which applications and users consume bandwidth, Ascent can make timely and cost-effective decisions regarding network troubleshooting and capacity planning.

In addition, ReporterAnalyzer enables Ascent to leverage its existing investment in Cisco equipment. ReporterAnalyzer works by capturing a rich set of traffic statistics exported by Cisco IOS(R) NetFlow on routers and switches. By enabling NetFlow on a few key aggregation routers and deploying ReporterAnalyzer -- a process which took just a few hours -- Ascent is able to easily extract and view the data needed for detailed traffic analysis.

ReporterAnalyzer's ability to scale to Ascent's enterprise network and store historical information were additional factors in Ascent's decision to deploy the product. ReporterAnalyzer is designed to handle the volume of NetFlow data typical in the world's largest networks, providing real-time visibility into enterprise-wide network traffic and access to more than a year's worth of data.

"Optimal application performance over the WAN is critical to Ascent's business," said Joel Trammell, NetQoS CEO. "By using SuperAgent and ReporterAnalyzer, Ascent now has insight into application and network behavior that will enable it to optimize performance for its global employees."

NetQoS recently announced the availability of the NetQoS Performance Center, a no-charge management portal that integrates data from NetQoS' products to offer network engineers, operations staff, IT managers and executives a faster way to diagnose performance problems, monitor SLA compliance, and plan capacity growth with Web-based views customized to their needs. In addition to SuperAgent and ReporterAnalyzer, the NetQoS product portfolio includes Allocate(TM) for IT cost accounting and NetVoyant(R) for device and infrastructure performance management.
