Extreme Pumps Up the Network

23 April 2007

The company is offering software and switching

options designed to offer richer functionality at a

lower cost.

Extreme Networks on April 23 will try to set itself

apart from larger networking companies by offering

lower cost and richer functionality in new software

releases and new switching options.

The latest release of the ExtremeXOS network

operating system adds support for Extreme's

SummitStack technology, allowing as many as

eight fixed configuration switches to operate as a

single virtual switch.

"All switches in a stack coexist with the same

binary image as the operating system, which

reduces the burden of having to upgrade multiple

images," said Scott Lucas, senior director of

solutions marketing at Extreme Networks, in Santa

Clara, Calif.

If one switch in the stack fails, it does not affect the

availability of the other switches in the stack,

making Extreme's stackables suitable for

supporting VOIP (voice over IP) traffic. A single

stack can support a mix of port configurations.

Extreme Networks implemented distributed control

of the Layer 3 protocol and the Internet

Engineering Task Force's Ethernet Automatic

Protection Switching Protocol to enable faster

failover.

ExtremeXOS also improves the security of

converged network designs where a computer is

plugged into an IP phone attached to the network

by treating the traffic stream from each as

separate, the company said. "We can detect both

those devices on a single port and apply a

separate policy to each," Lucas said.

The new Universal Port Manager in Extreme's

EPICenter management suite provides network

administrators with a graphical console to design

complex security and QOS (quality of service)

policies and troubleshoot them to ensure that they

will have their desired effect before moving into

production. It also allows the administrator to

monitor how the policies are performing.

"The policies are contained on the switch, so you

don't have to go to a central repository" that could

be overloaded by requests, Lucas said.

Extreme also added a new 10/100 switch to its

Summit lineup of LAN switches that allows

enterprises to buy an appropriate level of speed

and get the security, QOS and high-availability

features they need, the company said.

The Summit X250 series fixed-configuration

switches can exploit the advanced security, high-

availability and QOS functions in the ExtremeXOS

operating system at a 10/100 price point.

"We suspect people are buying Gigabit - Ethernet -

because it's the only way to get advanced

features," Lucas said. "With this we can hit a sweet

spot for telephony applications - that don't require

Gigabit Ethernet speeds - but all need advanced

security, high availability and so on. We're providing

those in speed and a form factor and price level

that makes sense," he said.

Such a move does not make sense to David

Passmore, research director at the Burton Group.

"An [application-specific integrated circuit] is an

ASIC. It doesn't cost Extreme more to put a

10/1000 port on their switch than a 10/100 - port - .

Why introduce a 10/100 switch when for very little

additional cost you could add Gigabit - Ethernet - ?"

Passmore said. "I understand there are many

enterprises that are perfectly happy with 10/100,

but why not future-proof it?"

The Summit X250 series is available in 24- and
