SCTP associations are comprised of the following attributes:

• Two SCTP terminals
• Protocol data state
• Active DATA chunk group

SCTP is a transport layer protocol operating through a connectionless packet network. This is an Internet Protocol (IP) for terminal communication regulation.

During transport, SCTP separates and identifies stream and DATA/control chunks as stream identifiers (SIs), stream sequence numbers (SSNs) and transmission sequence numbers (TSNs).

SCTP provides the following features:

• Error-free data transfer
• Sequenced and non-duplicated message delivery
• Optional single packet bundling
• Optional order of arrival delivery for individual messages
• Multihoming support at association endpoints
• Maximum transmission unit (MTU) path size for data fragmentation
