The IESG has approved the following document: - 'Sockets API Extensions for Stream Control Transmission Protocol (SCTP)' (draft-ietf-tsvwg-sctpsocket-32.txt) as an Informational RFC This document is the product of the Transport Area Working Group. The IESG contact persons are Wesley Eddy and David Harrington. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-tsvwg-sctpsocket/ Technical Summary The sockets API has provided a standard mapping of the Internet Protocol suite to many operating systems. Both TCP [RFC0793] and UDP [RFC0768] have benefited from this standard representation and access method across many diverse platforms. SCTP is a new protocol that provides many of the characteristics of TCP but also incorporates semantics more akin to UDP. This document defines a method to map the existing sockets API for use with SCTP, providing both a base for access to new features and compatibility so that most existing TCP applications can be migrated to SCTP with few (if any) changes. Working Group Summary There is strong consensus in the TSVWG among the participants involved in SCTP behind this document. There were several reviews during the WGLC, implemented many times, and there were no significant dissenting views expressed. Protocol Quality This SCTP Socket API is implemented in many code bases, namely FreeBSD/Linux/Solaris by the coauthors Thomas Dreibholz <dreibh@iem.uni-due.de> in the well-known SCTPLIB userland SCTP implementation, and in RSPLIB Irene Rüngeler in the INET framework which is a widely used part of the OMNeT++ simulation environment. "Becke, Martin" <martin.becke@uni-due.de> the described API as co-author of the measurement tool netperfmeter. Robin Seggelmann <seggelmann@fh-muenster.de> implemented SCTP support for OpenSSL and the API draft. Michael Tüxen <Michael.Tuexen@lurchi.franken.de> (a coauthor) the ID was also used for the SCTP kernel implementations in HP-UX and AIX. The FreeBSD implementation has been ported to Windows and Mac OS X. Jon Leighton <leighton@cis.udel.edu> implementations including creating SCTP enabled versions of NSPR, Firefox and Chrome, on multiple platforms. RFC Editor Note In the code samples in Appendix A and B, please add <CODE BEGINS> and <CODE ENDS> at the beginning and end of each of the example code files.
