If the message is too big to fit into a single DATA chunk and SCTP packet with keeping the SCTP packet size below the MTU, SCTP fragments the message and puts it into more than one DATA chunk in different SCTP packets.

SCTP places messages and control information into separate chunks (data chunks and control chunks), each identified by a chunk header. The protocol can fragment a message into multiple data chunks, but each data chunk contains data from only one user message. SCTP bundles the chunks into SCTP packets.
