SCTP

[Randall Stewart]

Bascially there are two socket models that
can be used by SCTP..

sd = socket(AF_INETX, SOCK_STREAM, IPPROTO_SCTP);

or

sd = socket(AF_INETX, SOCK_SEQPACKET, IPPROTO_SCTP);

The first one will then look JUST like TCP... aka you
can take ANY TCP app you have and it will work... only
thing you might need to do is convert TCP_MAXSEG
and TCP_NODELAY socket option calls to ones with SCTP
instead...

This is how I quickly converted several fun utilities..

The second model looks like UDP more or less. You
still need to do a listen() but other than that
you can just send and recv data...

Now George also convert his packet pounder program
(don't remember the name.. Geroge?)... and
if you want I can place a tar-ball of some app
programs up that I use for testing.. but of course ..sigh.. there
is no documenation .. so it might not be to useful :-0

Let me knof if you want a tarball up on sctp.org of app code :-0
