Hello Erik, Scrutinizer from http://www.plixer.com/ supports all of those features you listed and scales to over 100K flows/second. http://www.plixer.com/Scrutinizer-Netflow-Sflow/scrutinizer.html Good luck with your search. ------------------------------------------------------------------------------------------------------ Does anyone know of a netflow collector that will do the following. *Graph/List Destination Networks By Top AS *Graph/List Destination Networks By Top IP Address *AS Path Analysis *Traffic Type (ICMP, TCP, UDP, IPSEC, HTTP, SSH, SMTP, etc..) We will be using this to help us decide who to Peer with and what transit Providers to look at. I am familiar with Arbor Network's Peak Flow utility but it's a little too pricy. I also found AS-Stats https://neon1.net/as-stats/ look promising from the power point on their page. Thanks Erik
