This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. This document also 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. This document is in-depth and contains similar information as the International Engineering Consortiumęs tutorial.

Products

IntelliNet Technologies

IntelliNet Technologies offers an RFC standards-based implementation of SCTP as part of the SIGTRAN framework. The SCTP from IntelliNet could be seamlessly introduced into present IP networks, providing enhanced performance reliability and control functions. In addition, this robust protocol provides reliable transport in wireless networks and multimedia frameworks.

IntelliNet implements its SCTP directly on top of IP. The architecture is based on core SCTP modules that include the implementation stack, the API layer, and the IntelliSS7TM Middleware. The implementation stack is not OS-dependant and, therefore, supports interworking.

Compaq

Stream Control Transmission Protocol, the first in a line of Compaqęs offerings for next-generation protocol, ensures data is transported across the network, without error and in sequence. Using connection-oriented principles, SCTP creates an association between the endpoints of an SCTP session before data is transmitted. This association is maintained until all data has been successfully transmitted.

Compaqęs SCTP follows all the recommendations set forth by the SIGTRAN working group under the IETF. It is designed to replace the use of existing UDP and TCP transports in most scenarios.
