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.
