- Subject: [SCTP-Discussion] Number of streams in case of restart
- Date: Tue Feb 13 12:40:02 2001
- List-id: SCTP Discussions <discussion.sctp.de>
Dear all,
I need some lessons in SCTP restart behaviour.
Consider the following case:
Node A sends INIT with OS = 10, MIS=10
Node Z sends INIT-ACK with OS=10, MIS=10
Finally the association will be up with 10 streams in both directions.
Now node A fails and starts the restart procedure.
But Node A sends INIT with OS=10, MIS=5
Node Z can respond with OS = 5, MIS 10.
The association can be established with 10 / 5 streams.
Is this a valid restart szenario? Or is it invalid due to
the wrong numbers of streams?
Using the API in RFC the user at Node Z has to ask for
the number of streams using the sctp_status primitive after
the restart notification.
Best regards
Michael
