Transmission Sequence Number
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.
