Stream Control Transmission Protocol (SCTP)

This document obsoletes RFC 2960 and RFC 3309. It describes the Stream Control Transmission Protocol (SCTP). SCTP is designed to transport PSTN signaling messages over IP networks, but is capable of broader applications.

SCTP is a reliable transport protocol operating on top of a connectionless packet network such as IP. It offers the following services to its users: acknowledged error-free non-duplicated transfer of user data, data fragmentation to conform to discovered path MTU size, sequenced delivery of user messages within multiple streams, with an option for order-of-arrival delivery of individual user messages, optional bundling of multiple user messages into a single SCTP packet, and network-level fault tolerance through supporting of multi-homing at either or both ends of an association.

The design of SCTP includes appropriate congestion avoidance behavior and resistance to flooding and masquerade attacks.

The Stream Control Transmission Protocol (SCTP) is a reliable transport protocol operating on top of a connectionless packet network such as IP. It is designed to transport public switched telephone network (PSTN) signaling messages over the connectionless packet network, but is capable of broader applications.

This memo defines the Management Information Base (MIB) module which describes the minimum set of objects needed to manage the implementation of the SCTP.

This memo describes an extension to the Stream Control Transmission Protocol (SCTP) that allows an SCTP endpoint to signal to its peer that it should move the cumulative ack point forward. When both sides of an SCTP association support this extension, it can be used by an SCTP implementation to provide partially reliable data transmission service to an upper layer protocol. This memo describes the protocol extensions, which consist of a new parameter for INIT and INIT ACK, and a new FORWARD TSN chunk type, and provides one example of a partially reliable service that can be provided to the upper layer via this mechanism.

This memo describes an extension to the Stream Control Transmission Protocol (SCTP) RFC2960 [5] that allows an SCTP endpoint to signal to its peer that it should move the cumulative ack point forward. When both sides of an SCTP association support this extension, it can be used by an SCTP implementation to provide partially reliable data transmission service to an upper layer protocol. This memo describes (1) the protocol extensions, which consist of a new parameter for INIT and INIT ACK, and a new FORWARD TSN chunk type (2) one example partially reliable service that can be provided to the upper layer via this mechanism.

This document describes extensions to the Stream Control Transmission Protocol (SCTP) [RFC2960] that provides a method to reconfigure IP address information on an existing association.

This document is a compilation of issues found during six interoperability events and 5 years of experience with implementing, testing, and using SCTP along with the suggested fixes. This document provides deltas to RFC 2960 and is organized in a time based way. The issues are listed in the order they were brought up. Because some text is changed several times the last delta in the text is the one which should be applied. In addition to the delta a description of the problem and the details of the solution are also provided.

Stream Control Transmission Protocol (SCTP) currently uses an Alder-32 checksum. For small packets Adler-32 provides weak detection of errors. This document changes that checksum and updates SCTP to use a 32 bit CRC checksum.

This document describes the applicability of the Stream Control Transmission Protocol (SCTP). It also contrasts SCTP with the two dominant transport protocols, User Datagram Protocol (UDP) & Transmission Control Protocol (TCP), and gives some guidelines for when best to use SCTP and when not best to use SCTP.
