MANAGEMENT FRAMEWORKS ARE OUT - BUT WHAT'S IN?

Many vendors stopped using the term "frameworks" when they
became synonymous with endless deployment cycles. So, if
management frameworks are out, what is the alternative? Does a
series of multiple products from multiple vendors work? Will
Configuration Management Database (CMDB) emerge as the new
"framework" or "platform" for the enterprise? Click here for

Today's focus: User gets flexible compression

By Denise Dubie

Chris Sherwood was ready to upgrade his load-balancing and
compression tools in order to get something that could handle
gigabit speeds. In the process, he came upon a better way to
compress - or in some cases, not compress - data being
distributed across the company network to some 200,000 end
users.

Sherwood, network operations manager at Rappatoni, an
Internet-based Multiple Listing Service (MLS) real estate
provider, in Simi Valley, Calif., says his former compression
technology from NetScaler
<http://www.networkworld.com/news/2005/070405-netscaler.html?rl>
didn't allow him as much control or flexibility over how to
manage application traffic. He refers to the tools from
NetScaler and his specific implementation as a "light switch" of
sorts that only allowed him to choose on or off when it came to
compression.

"In the NetScaler box the compression was on or off for the
entire unit, which wasn't ideal for us," Sherwood explains.

Following reviews of an upgraded product from NetScaler and one
from F5 Networks, Sherwood decided upon F5's Big-IP application
traffic management product
<http://www.networkworld.com/news/2004/0831f5jams.html?rl>.
While he experienced some problems getting the Big-IP appliances
to synchronize, Sherwood says now he can better control the
amount of compression applied to application traffic and even if
it gets compressed at all.

"Compressing everything slowed some applications down,
actually," he says. "Often the time it takes to decompress data
would lengthen the entire process, so not compressing it at all
was a better option."

F5 calls its technology intelligent compression, saying that
"compression is not a one-size-fits-all technology. Compression
that lacks intelligence and granularity can actually hurt
end-user performance, especially for those clients accessing an
application via a broadband connection with low latency."

Sherwood says he likes that he can apply policies and rules to
different applications to better manage how the traffic
traverses his net.

"We can set compression at 10 different levels, and depending on
the importance of the application or the end users, we can
decide which rules to apply," he says.
