New Select(TM) Bandwidth Manager for Citrix Presentation Server(TM) Provides Cost-Effective, On-Demand Access Into Application Performance at Local and Remote Sites LAS VEGAS, Oct. 10 /PRNewswire-FirstCall/ -- At the Citrix iForum(TM) Global 2005, Visual Networks, Inc. (NASDAQ:VNWK) (Booth #601), a leading provider of network and application performance management solutions and a Citrix(R) Alliance Partner, today announced the forthcoming release of a new software solution that provides in-depth visibility into published applications under Citrix's standard ICA(R) protocol. The offering, Select Bandwidth Manager for Citrix Presentation Server, enables IT managers to identify bandwidth utilization on a per-user, per-application basis while also having end-to-end visibility into all Citrix-published applications and non- Citrix applications traversing the network -- at both local and remote sites. This new solution is a module of Visual Networks' flagship Visual UpTime(R) Select(TM) product suite, which provides in-depth, real-time and historical information that enables organizations to intelligently manage application and network performance and availability across the entire enterprise. "This new solution from Visual Networks allows IT managers to quickly and easily determine how much bandwidth each Citrix user or site requires, thereby enabling enterprises to proactively improve application performance across the network," said David Jones, corporate vice president, business development and corporate affairs, at Citrix. "This offering also optimizes troubleshooting of challenging issues such as remote printing and VoIP deployments." Select Bandwidth Manager for Citrix Presentation Server lets users identify the applications traversing the network, both Citrix and non-Citrix, how those applications are performing, and how much bandwidth they are consuming. Leveraging this intelligence, Visual UpTime Select enables IT managers to identify potential application performance issues and determine whether these problems are due to end-user, network, or server issues. For example, many Citrix performance problems are due to network issues since Citrix application traffic may be squeezed by a variety of other types of traffic, including non-Citrix applications, worms and viruses, and un- authorized applications, such as peer-to-peer file sharing. "Visual Networks is able to offer a rich set of application performance management functionality at a price point far less than what Citrix customers might expect," said Bernd Harzog, CEO of Applications Performance Management Experts. "Additionally, with many Citrix users concentrated at remote office locations, Visual Networks' strong branch office management functionality is ideal for Citrix users to manage application performance and bandwidth utilization." The bursty nature of all application traffic creates intermittent problems that are difficult to diagnose without having real-time and historical visibility into network and application performance provided by Visual UpTime Select. And, with proactive alarming when usage or response time exceeds a pre-determined threshold, enterprises can optimize end-user quality of experience for key applications. "The introduction of this offering enables us to extend the intelligence we can deliver regarding the applications that traverse the network," said Larry Barker, President and CEO of Visual Networks. "We continue to invest significant resources in Visual UpTime Select to strengthen its ability to proactively manage application performance." The company anticipates general availability of Select Bandwidth Manager for Citrix Presentation Server in early 2006. Pricing begins at $2500 per site.
