No, it's not.  SCTP is message-oriented (like UDP) where TCP is
stream-oriented.  This eliminates the need for message framing at the
application level.  SCTP also supports multicast.  Unlike UDP,
however, lost packets are detected at the protocol level.

I don't understand the need for a lib though.  Many years ago, I was
experimenting with SCTP, and I didn't use any library.  It was all
done with extended parameters for socket() and some setsockopt()
calls.  I guess that was before the wrapper-lib-for-everything madness
completely took over.
