Traffic management becomes critical as your network
infrastructure expands to support different types of traffic and
users. Most traffic management solutions have serious
limitations: too expensive, difficult to use, and overly taxing
on bandwidth. However ProCurve Networking by HP addresses these
requirements, overcomes the limitations of other solutions, and
gives you valuable insight into LAN performance. Click here to

FORMULATING A TELEWORK SUPPORT STRATEGY

Has the increase in fuel prices spurred an increase in telework
at your company? Responsibility for managing teleworkers

Today's focus: What's driving WAN complexity? Part 2

By Steve Taylor and Jim Metzler

Last time, we discussed a survey that we recently conducted to
identify the type of activities that will have the greatest
impact on IT organizations over the next year. We mentioned that
the top-two activities cited by the survey respondents were
compliance and security. Today, we'll look at the other two top
activities that followed behind: VoIP and WAN redesign.

Given all the discussion of VoIP over the last several years, it
would be reasonable to believe that the major VoIP deployments
have been done and the ongoing impact of VoIP on IT budgets and
infrastructure is minimal. However, roughly two-thirds of the
survey respondents indicated that VoIP deployment would have at
least some impact on their IT budget and infrastructure over the
next year.

As was the case with security and compliance, there is
significant overlap in terms of VoIP deployment and WAN
redesign. In particular, the vast majority of survey respondents
who indicated that VoIP deployment would have at least some
impact on their IT budget and infrastructure also indicated that
their company was undergoing at least some WAN redesign.

That overlap is a result of IT organizations needing to redesign
their WAN in order to support VoIP and other demanding
applications. For example, one survey respondent stated that in
order to support applications such as VoIP and IP video, his
organization was "going through the painstaking activity of
migrating to MPLS, including the use of Virtual Private LAN
Services."

We'll revisit the topic of MPLS in future newsletters when we
explore the MPLS services available from the major carriers. In
the meantime, you can review our previous newsletters about MPLS
in private networks: " Private MPLS nets give organizations more
control over their WANs <http://www.networkworld.com/nlwan7126>
"; " Supporting VPNs within MPLS networks
