Interop: Virtualization Is Top Monitoring Challenge, Survey Shows

The job of network professionals is becoming more complex, as engineers increasingly deal with WAN optimization and virtualization, a NetQoS exec said.

Virtualization ranked as the top monitoring challenge among attendees of the Interop conference in Las Vegas, a survey showed.

Thirty-eight percent of respondents to the survey of 117 network engineers placed virtualization at the top among emerging technologies, while 24% were most concerned with unified communications and 14% with the data-carrying mechanism called Multiprotocol Label Switching, according to Network Instruments and NetQoS, the two vendors who released the poll Wednesday.

The survey also found that half of the respondents' organizations had deployed some virtualization technologies. That percentage is expected to increase to 79% within 12 months and 82% in two years. Fully 41% of organizations do not run virtualization, and the remaining respondents didn't know.

Internet telephony has a strong presence, with 67% of respondents saying their organization had implemented voice over IP on their networks. Most of the organizations had implemented VoIP products from Cisco Systems, followed by Avaya and Microsoft. Looking to the future, 7% of the respondents said they expected to implement VoIP within 12 months, and an additional 3% expected to wait more than a year.

Asked about WAN-optimization technology, 42% of the engineers had implemented it or expected to within 12 months. Fully, 44% had no plans to use the technology.

When asked about topologies, 69% said they are interested in monitoring LANs, 60% in WANs, 56% in wireless, 48% in Gigabit Ethernet, and 23% in 10 Gigabit Ethernet.

Patrick Ancipink, director of product marketing for NetQoS, said the survey showed that the job of network professionals is becoming more complex, as engineers increasingly deal with new technologies, such as WAN optimization and virtualization.

"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," Ancipink said in a statement.
