One of the most fun yet scariest parts of being an entrepreneur is making predictions. If your forecast is correct, hopefully it will be good for your company. If you are wrong, you hope no one notices. In 2009 I posted a blog titled OMG, the Internet is overloaded! where I discussed application recognition and its importance in the role of prioritizing traffic. In the post I stated “Due to the fact that many applications use the same ports, application recognition is no simple process (e.g. Skype ‘VoIP’ looks like BitTorrent ‘data’). My guess is that accurate application awareness is a highly dynamic problem necessitating frequent updates.” Today, several vendors now perform Deep Packet Inspection (DPI) to monitor a series of packets to identify layer 7 applications. Cisco Application Visibility and Control uses NBAR to serve just this purpose. Below I’ve listed a few companies that utilize DPI to identify layer 3 applications:Michael Patterson
