LAS VEGAS -- As more companies deploy virtualization technologies, more network managers expect the technology to introduce management challenges to their environments, according to an Interop show poll.
Virtualization is a hot topic at the Interop conference this year, and more than 50% of 117 attendees surveyed reported that their organizations have deployed some virtualization
technologies. More than 41% do not currently run virtualization, but close to 80% said they would have virtualization in-house
within the next 12 months. And the number of show attendees polled planning to use virtualization technology is set to increase
to 82% in two years.
But nearly 40% of network managers polled also listed virtualization as the emerging technology that represents the "greatest
monitoring challenges," according to NetQoS and Network Instruments, which jointly conducted the survey Tuesday following the opening of Interop's exhibition area. Network performance management
vendor NetQoS and Network Instruments, which provides network and application analysis, monitoring and reporting products,
also discovered that 24% of those polled consider unified communications a potential monitoring challenge and 14% identified MPLS as a technology that might introduce new monitoring issues. (Compare Network Monitoring and Management products.)
"Many of the people we're speaking with today are talking about network-wide rollouts of new applications like VoIP and unified communications," said Charles Thompson, manager of systems engineering for Network Instruments, in a statement.
"Many IT staffs find it challenging to assess how these applications will impact the performance of other business-critical
applications."
The survey also checked with attendees to get a sense of the types of networks they monitor and the specific technologies
they have implemented or plan to implement in the coming months. Nearly 70% of attendees said they are interested in monitoring
LANs, nearly 60% said WAN management tops their mind and close to 56% indicated they are tasked with monitoring wireless networks. About 50% monitor gigabit networks and more than 20% work with 10 Gigabit networks.
In terms of VoIP, nearly 70% of show attendees polled have implemented the technology and another 10% said they expect to
implement VoIP in the next year or more. Forty-six percent surveyed at Interop are using Cisco for their VoIP implementations, while 18% work with Avaya products. Close to 10% use Microsoft VoIP technology and 8% use Nortel.
WAN optimization technologies are also deployed in many IT shops. More than 40% have or plan to implement WAN optimization technology within
12 months. Yet 44% indicated in the poll that they had no plans to roll out the technology.
"The job of the network professional is becoming more complex, with increasing responsibility for maintaining optimum application
performance while dealing with new technologies such as WAN optimization and virtualization," said Patrick Ancipink, NetQoS
director of product marketing, in a statement. "The organizations that adapt best to the emerging trends and challenges outlined
in the survey are those that can understand the before and after impact of change on network and application performance and
work well across IT silos for planning and troubleshooting purposes."

Improving Application Performance Troubleshooting
Diagnosing why an application is slow is hard, at times taking days or weeks to isolate and resolve. This paper explains the challenges involved using current management tools, provides a 'wish list' for application management and analysis, and explains the need for an application system-wide approach that monitors entire applications, not components.

Virtual Vigilance: Managing Application Performance in Virtual Environments
This paper highlights the impact of virtualization on application performance. "Managing Application Performance in Virtual Environments" states: "Best-in-Class organizations are predominately taking actions around improving visibility across both physical and virtual systems, assessing the business impact of application performance and understanding interdependencies of applications in virtualized environments."
