Hello Pascal

   - 4. Section 5.2, the fourth paragraph at the end, says, "The session
   can be associated one-to-one with a ... connection."

- What represents a session association? Do you mean the session uses the
IP address?

The text says

"

For instance, the SCHC session can be associated one-to-one with a tunnel,
a TLS session, or a TCP or a PPP connection.

"

The way to recognize one of those things depends on that thing. The IP
address is usually part of that. But say you do SCHC over MPLS, then it
will be the label.

- Are you thinking of something else?

Yes.

[Ana] This is very interesting because while reading, I understood that the
IP address or MPLS label is insufficient to identify the session.

So the Rule manager needs to record a triplet of the session ID, IP
address/MPLS label, and something else to recognize the correct instance.
What does this third element mean?
