[MMUSIC] Connection and connectivity preconditions

[Gonzalo Camarillo <[e-mail]>]

Folks,

in the last IETF we discussed how to proceed with the following both drafts:

draft-andreasen-mmusic-connectivityprecondition-02.txt
draft-ietf-mmusic-connection-precon-01.txt

The former defines connectivity (e.g., RTP No-Op or ICE-based) 
preconditions and the latter defines connection-oriented (e.g., TCP or 
SCTP-based) preconditions.

The question is what to do to handle scenarios using connection-oriented 
protocols. The choices are:

1) Merge both documents so that only one precondition type is defined 
which, for connection-oriented protocols, is met when the connection 
establishment procedure finishes (e.g., a successful TCP 3-way handshake).

2) Leave the second draft as it is and define in the first draft further 
conditions that should be met for connection-oriented protocols. For 
example, the connection establishment procedure needs to be successfull 
*and* you have to run some type of connectivity check on top of it to 
ensure that you are talking to the correct remote endpoint.


In principle, Flemming and I thought that option 1) was the way to go, 
but in the meeting some folks talked about option 2).

Given that, at present, nobody is implementing something like option 2) 
(if somebody is doing it please speak up), my proposal would be to go 
for option 1).

Comments?

Thanks,

Gonzalo
