DOES WMM MAKE YOU GO HMMM?

Eager to spur interoperable QoS among different vendors'
wireless gear, the Wi-Fi Alliance developed the Wi-Fi Multimedia
(WMM) specification. WMM is designed to support consumer and
corporate applications and works with all three 802.11 wireless
physical layer standards. For more on how WMM handles the
prioritization of data packets, DCF, CM and more, click here:

Today's focus: What are the next steps for VoIP?

By Steve Taylor and Larry Hettick

At last week's Next Generation Networks conference held in
Washington, D.C. we had the chance to attend several interesting
panel discussions but none more interesting than the discussion
about upcoming challenges for VoIP. In fact, most of the buzz at
NGN was about VoIP, convergence and IP Multimedia Subsystem
<http://www.networkworld.com/news/2005/092005-ims.html?rl>.

The VoIP panel discussion, entitled "VoIP's Next Challenges,"
included panelists Larry O'Pella director of strategic solutions
at Alcatel, Chris Miller distinguished member of consulting
staff for Lucent Worldwide Services, and Mike Hluchyj founder
and CTO of Sonus Networks.

Hluchyj noted that the issues discussed were VoIP's next steps
rather than challenges. Among those steps is the deployment of
VoIP in endpoint broadband access devices, said Hluchyj. He also
highlighted the deployment of VoIP over mobile EV-DO Rev A
networks, noting that mobile operators can get more than 50% of
increased spectrum efficiency using Rev A, as opposed to the
previous 1XRTT EV-DO versions. He predicted that VoIP's
acceptance would proceed even more quickly for mobile operators
than for wireline operators due to the mobile carriers' rapid
deployment of broadband access.

He also commented about the need for VoIP packet peering.
Although he correctly pointed out that peering architecture can
open the network to security threats, the use of "network border
switching" (a.k.a. session border controllers) can counter VoIP
packet peers by surrounding and protecting the individual
networks.

Hluchyj also noted that additional work on security is needed,
especially in the areas of traffic policing, authentication,
encryption and trust.

Next time, we'll highlight Lucent's Chris Miller's comments. Do
you agree or disagree with Hluchyj's observations? Please feel
free to e-mail us with your thoughts.
