WHY ISN'T WIRELESS SPAM BEING STOPPED?

Wireless spam has the potential to become even more vexing than
e-mail spam. Because wireless spam is still in its infancy in
this country, carriers are just beginning to respond to the
problem. But are their efforts aggressive enough? Find out what
might be keeping the carriers from stopping spam. Click here:

Today's focus: Juniper extols WAN optimization best practices

By Denise Dubie

With the acquisitions of Peribit and Redline Networks under way
<http://www.networkworld.com/news/2005/0426junibuy.html?rl>,
Juniper is well on its way to becoming a pivotal player in the
WAN optimization market.

The vendor recently laid out best practices for achieving
LAN-like performance over enterprise WANs in a company white
paper <http://www.networkworld.com/nlnetop4914> posted this
month. To start, Juniper advises against a bandwidth buy, just
in case the costs - in both time and money - outweigh the
benefits. In many cases, the paper points out a poorly
configured application could be the culprit behind slow-moving
wide-area applications
<http://www.networkworld.com/nlnetop1530>. Juniper says its
compression and caching technology can help enterprise IT
managers "gain instant WAN capacity on the existing network."

In terms of speeding traffic over wide-area links, latency
<http://www.networkworld.com/news/2003/0922peribit.html?rl>
poses the biggest challenge, Juniper says in this paper. WAN
optimization and application acceleration platforms require both
TCP acceleration and application-specific acceleration. "Latency
affects application performance because the underlying protocols
rely on a back-and-forth sequence of data transmissions and
acknowledgements," the paper explains.

Following bandwidth and latency concerns, enterprise IT managers
should direct their attention toward QoS support and
configuration, according to Juniper
<http://www.networkworld.com/careers/2005/051605man.html?rl>.
Because speeds between the LAN and the WAN differ, "contention
for WAN real estate is a very real problem that needs to be
addressed with an effective and realistic QoS and bandwidth
allocation model," which can also be aligned with a company's
specific business priorities, Juniper says.

Juniper goes on to detail how network placement, deployment
flexibility and ease of use will help IT managers reap more
benefits from their WAN optimization and application
acceleration platform. Other factors to consider include using
multiple WAN links, monitoring tools and scalability. Lastly,
Juniper recommends IT managers seriously incorporate security in
their WAN optimization plans.
<http://www.networkworld.com/nlnetop4915>

"Enterprises no longer have the luxury of securing just their
private WANs and avoiding the Internet for business
transactions," the paper states. "IT needs tools to make all
transports secure enough for these business transmissions."
