SCTP - Stream Control Transmission Protocol

SCTP provides sequential, reliable delivery of higher layer data, using logical streams to separate this functionality and hence avoid head of line blocking. An SCTP connection between two network nodes e.g. eNB (Evolved Node B) to MME (Mobility Management Entity) is termed an SCTP Association, which can feature flow control and multihoming as standard capabilities. SCTP provides much of the same functionality as TCP (Transmission Control Protocol), without the inherent drawbacks that TCP can suffer from.
