Great article! I have seen your book at the store and online and can't wait until I buy it! It will be my Xmas present. Until then I am using your manual (which is a excellent document).

SANS is using it and they are taking it in the right direction.NetFlow Visualization
Thanks for the article. Traffic visualization is very important.I thought you would like to know that Plixer International is doing some very interesting things with visualizing NetFlow traffic. They store long term data like most NetFlow tools, but they are definitely spicing things up with some very cool ways to look at the data.
Take a look.
