We've been tracking this dynamically for a while in order to make sense of flow data traces - using a plethora of reliable (as well as dubious!) sources - including running some of the more popular p2p apps to see what ports they choose. Of course, there are many problems with using tcp/udp ports to identify apps - some apps use randomly assigned ports (sometimes after negotiating the connection on a well known port; like most streaming video protocols); some apps allow users to override ports, which many users do in order to circumvent firewalls; and there is much duplication across ports. But, try the attached lists (one by port, one by app, and one shows a grouping we use for "common application classes" e.g. "mail" or "peer to peer" etc.). I'd greatly appreciate fixes or updates. [NOTE: attachments not sent to nanog-post - if you want them, email me privately.] Of course if you really want to accurately account for traffic by application, there is no substitute for passive sniffing of full headers (not scaleable, and certainly can raise privacy issues). -fred
