Abstract

A system monitors first traffic and identifies associations between applications that generated or received the traffic and parameters such as domain names, a remote host, and a local host referenced in the traffic. Subsequent traffic is monitored and determined to be generated by or addressed to an application according to such parameters in the subsequent traffic, such as remote host, local host, domain name, or port number. The subsequent traffic is associated with an application without requiring deep packet inspection (DPI). In particular, an application may be associated with a session based on evaluation of a single packet of the session.
