FROM THE NETWORK CORE TO THE NETWORK EDGE

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

SPYWARE SHOOTOUT

Need to defend your network from spyware? Lots of tools and
software have hit the market recently, and network executives
are left to decide which weapon works best. Our Spyware Shootout
2005 suggests the gateway approach might be the best starting
point but is it a long-term strategy? Click here for more:

Today's focus: Start-up eyes WAN optimization

By Denise Dubie

Silver Peak Systems says it has a better way to transfer data
over wide area links. The premise is that it doesn't transfer
the data as often as it's requested or in its complete form.

It's not a new concept to reduce the amount of packets, bytes,
files and traffic that traverse corporate WANs to optimize
performance <http://www.networkworld.com/nlnetop7160> , but
start-up Silver Peak believes it is achieving the end goal of
reduced congestion and latency on the WAN in a unique way. The
Mountain View, Calif., company, which raised some $12.5 million
in venture funding, this week will begin shipping its flagship
product suite.

Silver Peak's Network Memory employs technology that the company
dubs local instance networking, in which the appliance watches
traffic and recognizes patterns. The product comprises
appliances loaded with software and installed at either end of a
WAN link - for example, in a data center and at branch offices.
When the data center appliance sees a pattern of bytes that it
remembers already sending over the WAN, it will only send a
reference to the branch office box, letting it know the box
already has all or parts of the content and telling it to
forward the content on to the requesting end user.

The data center appliance can be used to optimize traffic at
either Layer 2 or Layer 3, sitting behind the router or peering
with it <http://www.networkworld.com/nlnetop7161> , and the
branch appliance sits behind the router. The appliances are
unaware if the packets they are passing along contain e-mail or
a PowerPoint presentation; they just identify that a particular
sequence of data has been repeated and does not need to be sent
over WAN links again. Company officials say that, unlike some
application acceleration tools, Network Memory can optimize any
type of traffic, including TCP, UDP and more.

"We are not simply a TCP proxy or TCP-only; we can optimize
proprietary applications, streaming traffic and UDP," says Craig
Stouffer, vice president of worldwide marketing. The appliances
are also loaded with storage, up to 2 terabytes in the data
center and less for local appliances, to provide customers with
adequate memory for weeks and potentially years depending on the
content, the company says.

With its dual-box architecture, Silver Peak will compete with
the likes of Peribit (which has been acquired by Juniper
<http://www.networkworld.com/news/2005/0426junibuy.html?rl> )
and Riverbed, but company officials say the product would be
complementary to tools from the likes of NetScaler (recently
acquired by Citrix <http://www.networkworld.com/nlnetop4677> ),
F5 Networks and Redline Networks (also acquired by Juniper),
which can help customers reduce the number of servers needed in
a data center to speed Web application traffic over the WAN.

Available now, the Silver Peak Network Memory appliances come in
three flavors: the NX-2500, a 1U appliance for branch offices
that costs about $10,000; the NX-3500, a 2U appliance for
regional hubs and small data centers that costs about $18,000;
and the NX-7500 for large data centers that costs about $50,000.

FEATURED READER RESOURCE

IS IT THE NETWORK OR THE STORAGE THAT'S THE PROBLEM?

Midsize and larger businesses often find their IT topology has
become a complex mix of servers, networks and storage systems.
Many of these companies also route long-haul traffic over
fiber-based networks - metropolitan-area networks, WANs and
private optical networks. Who's responsible when a
storage-related problem occurs on a fiber network? For more,
