that would be the easy bit ... hopefully only peripheral changes will be
required ; like to glue in timers, execution flow, memory management and
tx/rx of packets.
I would be interested in any bug fixes. You might also want to make the
prototype implementation more robust against misbehaving peers.

I would be most happy to hear from someone who has ported sctp to an
embedded platform. My first concern is whether it requires a pre-emptive
OS ? our OS is all message passing, all threads run to completion, no
pre-emption possible.
It should be OK for the sctplib.

Do you use a commercial OS on your box? Does it provide a build in SCTP stack?

It is a modular router with lots of PBX and VoIP protocols supported. We
are looking for sctp to support several hundred associations being various
signalling protocols over RTP.
You want to move protocols running over RTP/UDP/IP over to SCTP/IP?
