  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).
