Re: [Dime] open issues #1 in DOIC

[<[e-mail]>]

Actually, I realized that we are redefining something somehow already in use in RFC 6733:

9.6. Correlation of Accounting Records


   If an application uses accounting messages, it can correlate
   accounting records with a specific application session by using the
   Session-Id of the particular application session in the accounting
   messages.  Accounting messages MAY also use a different Session-Id
   from that of the application sessions, in which case, other session-
   related information is needed to perform correlation.

We could maybe reuse the same type of wording to simplify the definition:

Pseudo-session applications are applications that
do not rely on the Session-Id AVP for correlation 
of application messages related to the same session
but use another session-related information for this
purpose. The 3GPP defined Cx application [3GPP.29.229]
is an example of a pseudo-session application.

OK?

Lionel

   Pseudo-session applications:

      While this class of application does not use the Diameter
      Session-ID AVP to correlate requests, there is an implied ordering
      of transactions defined by the application and except for the
      Session-ID differences pseudo-session based applications are
      generally assumed to behave like session-based application.  The
      3GPP defined Cx application [3GPP.29.229] is an example of a
      pseudo-session application.


Would this suffice?

So it is implied that the same server is contacted by the client managing the session. In the Cx example, the same origin-host will be used in the client-initiated requests after the initial exchange and the server discovery phase.
