Deep diving into deep packet inspection

Michael Morisy Michael Morisy Profile: Michael Morisy

Speaking of deep packeteering, is a new non-profit with the goal to “foster and support community interest and progress in deep packet inspection (DPI).” OK, so the Gates Foundation it’s not, but I got on the phone with two of the founders, Kyle Rosenthal and Axel Weichert, both formerly with DPI provider Bivio Networks, yesterday to talk a little bit about the site’s ambitions and how it might help network engineers who are tackling how to integrate DPI into their networks.

They said they initially set out to create a very technical community, but they’ve since broadened that mandate to include high-level discussions about the place of DPI at both the network and service provider level. That topic tends to bring out ideologues on both sides, particularly as it’s linked to net neutrality, but hopefully the savvy searcher can avoid the worst of the flame wars and find some useful information, such as vendor profiles and a piece on using DPI to check and improve Skype traffic.

Rosenthal said one of dPacket’s big challenges would be to prove to readers that the site isn’t an industry mouthpiece, which might be tough with financial sponsors like Sandvine and Ellacoya. Still, the more resources there are for complex subjects like DPI the better, particularly if they are willing to tackle both the tough technical aspects of network deployment alongside the creation of ethical guidelines to address how far into the network should DPI peer, and how that information should be handled.
