Chapter 13 - Stream control transmission protocol. Upon completion you will be able to: Be able to name and understand the services offered by SCTP, understand SCTP’s flow and error control and congestion control, be familiar with the fields in a SCTP segment, understand the phases in an SCTP association, understand the SCTP state transition diagram. | Chapter 13 Upon completion you will be able to: Stream Control Transmission Protocol Be able to name and understand the services offered by SCTP Understand SCTP’s flow and error control and congestion control Be familiar with the fields in a SCTP segment Understand the phases in an SCTP association Understand the SCTP state transition diagram Objectives TCP/IP Protocol Suite Figure TCP/IP protocol suite TCP/IP Protocol Suite SCTP is a message-oriented, reliable protocol that combines the good features of UDP and TCP. Note: TCP/IP Protocol Suite SCTP SERVICES We explain the services offered by SCTP to the application layer processes. The topics discussed in this section include: Process-to-Process Communication Multiple Streams Multihoming Full-Duplex Communication Connection-Oriented Service Reliable Service TCP/IP Protocol Suite Table Some SCTP applications TCP/IP Protocol Suite Figure Multiple-stream concept TCP/IP Protocol Suite An . | Chapter 13 Upon completion you will be able to: Stream Control Transmission Protocol Be able to name and understand the services offered by SCTP Understand SCTP’s flow and error control and congestion control Be familiar with the fields in a SCTP segment Understand the phases in an SCTP association Understand the SCTP state transition diagram Objectives TCP/IP Protocol Suite Figure TCP/IP protocol suite TCP/IP Protocol Suite SCTP is a message-oriented, reliable protocol that combines the good features of UDP and TCP.

Note: TCP/IP Protocol Suite Figure Multihoming concept TCP/IP Protocol Suite SCTP association allows multiple IP addresses for each end. Note: TCP/IP Protocol Suite SCTP FEATURES We discuss the general features of SCTP and then compare them with those of TCP. The topics discussed in this section include: Transmission Sequence Number (TSN) Stream Identifier (SI) Stream Sequence Number (SSN) Packets Acknowledgment Number Flow Control Error Control Congestion Control TCP/IP Protocol Suite In SCTP, a data chunk is numbered using a TSN. Note: TCP/IP Protocol Suite To distinguish between different streams, SCTP uses a SI. Note: TCP/IP Protocol Suite To distinguish between different data chunks belonging to the same stream, SCTP uses SSNs. Note: TCP/IP Protocol Suite Figure Comparison between a TCP segment and an SCTP packet TCP/IP Protocol Suite TCP has segments; SCTP has packets. Note: TCP/IP .
