1. Overview
A. Definition
- Developed to support transmission of Voice over IP (VoIP) signal relay and multimedia applications that are not supported with existing TCP.

- Development of VoIP transmission standards for IP networks is a major goal and RFC 2960 was established in October 2000.
- Multi-streaming function is required and is being developed by Transport Area WG.
C. Features
- combines UDP datagram orientation with TCP sequencing and reliability features
- Multi-stream and message-oriented transfer characteristics in multi-homeing environments
2. SCTP Structure and Packet Structure
A. Rescue
B. Packet structure
3. Status of SCTP development
A. Relevant IETF standard documents
- The SCTP base specification document is RFC 2960 and is a supplement to RFC 3257, 3286 documents
- Transport layer security documents related to SCTP are established as RFC 3436.
4. Conclusion and Future Prospect
- SCTP is the next-generation transport layer protocol after TCP and is expected to continue to expand and distribute standards.
- Used inside LTE and can be used on the internet in the future
