Death to Deep Packet (layer 7 shaping) Inspection

Editors note: Deep packet inspection (layer 7 shaping) will likely be around for a while. It is very easy to explain this technology to customers, hence many IT resellers latch on to it as it makes a compelling elevator pitch.  We put out the press release below to formalize our position on this issue.

For detailed information on how the techniques of NetEqualizer differ from Deep Packet inspection, see the following link:

LAFAYETTE, Colo., October 28, 2008 — APconnections, a leading supplier of plug-and-play bandwidth shaping products, today made a formal announcement to formally discontinue  deep packet inspection techniques in their NetEqualizer product line.

“Our behavior-based techniques worked so well that current customers stopped asking for the layer-7 techniques we had at one time implemented into our system,” said Art Reisman, CEO of APconnections. “So, we eventually just decided to phase the technique out completely.”

Although deep packet inspection, also known as layer-7 shaping, was unofficially discontinued nearly two years ago, the ongoing debates over user privacy spurred the official announcement.

“What prompted us to make a formal announcement was the continued industry lack of understanding that deep packet inspection not only does not work very well, but it also puts you are at risk of violating privacy laws if you use these techniques without customer consent,” said Reisman.

Although Reisman says most providers cross this line with the good intentions of controlling traffic congestion, the reality of it is that it’s no different than listening to a private phone conversation and terminating the call if you don’t like what you hear.

“It’s quite risky  that any public US based ISP would invest in  this technique, especially after the FCC slapped Comcast’s wrists in a recent decision” said Riesman.

The NetEqualizer is a plug-and-play bandwidth control and WAN/Internet optimization appliance that is flexible and scalable. When the network is congested, NetEqualizer’s unique “behavior shaping” technology gives priority to latency sensitive applications, such as VoIP and email. It does it all dynamically and automatically, improving on other bandwidth shaping technology available.

APconnections is a privately held company founded in 2003 and is based in Lafayette, Colorado.
