hi,

it is possible to use more than one association in each user application of
the sctpd.
The simple reason is that what the UDP messaging does is just to send the
notifications and function calls with their associated parameters to and
from between the daemon and the user applications. If you look at the API of
the sctplib, in cases where it is significant to know which association the
notification or function call relates to, the assoc ID is usually provided
as one of the paramter. Like other parameters, it will be passed between the
daemon and the user application. There is no need to change the "protocol".

hope this answers your question.

Hi Andreas,

Will it be possible to control and use more than one association in
the sctplib instance in the sctpd?

If so, does that mean there is a new sctpd protocol wrapper for
datagrams exchanged between the user app and the sctpd to
differentiate between datagrams belonging to different associations?

Could I get a peak at the upcoming documentation for sctpd?

Michael
