A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the IPNG Working Group of the IETF.

Title : Basic Socket Interface Extensions for IPv6 Author(s) : R. Gilligan, S. Thomson, J. Bound, W. Stevens Filename : draft-ietf-ipngwg-bsd-api-new-05.txt Pages : 33 Date : 05-Jan-99

The de facto standard application program interface (API) for TCP/IP applications is the 'sockets' interface. Although this API was developed for Unix in the early 1980s it has also been implemented on a wide variety of non-Unix systems. TCP/IP applications written using the sockets API have in the past enjoyed a high degree of portability and we would like the same portability with IPv6 applications. But changes are required to the sockets API to support IPv6 and this memo describes these changes. These include a new socket address structure to carry IPv6 addresses, new address conversion functions, and some new socket options. These extensions are designed to provide access to the basic IPv6 features required by TCP and UDP applications, including multicasting, while introducing a minimum of change into the system and providing complete compatibility for existing IPv4 applications. Additional extensions for advanced IPv6 features (raw sockets and access to the IPv6 extension headers) are defined in another document [4].

Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-ietf-ipngwg-bsd-api-new-05.txt".

NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
