Abbreviated as TSN, a Transmission Sequence Number is a 32-bit sequence number used internally by SCTP (Stream Control Transmission Protocol). A TSN is attached to each unit of information within an SCTP packet (also called a chunk) containing user data to permit the receiving SCTP endpoint to acknowledge its receipt.
