Each accounting session has a unique session ID, which is chosen by the NAS. The session
ID is carried in an Acct-Session-Id attribute, that should be present in every packet
involved in the session. The accounting packets typically do not use the same UDP port as
the authentication packets. The default port for RADIUS accounting is 1813.
