This document provides the External Data Representation (XDR) description for NFS version 4 minor version 2.

The Network File System (NFS) version 4 protocol is a distributed file system protocol that owes its heritage to NFS protocol version 2 (RFC 1094) and version 3 (RFC 1813). Unlike earlier versions, the NFS version 4 protocol supports traditional file access while integrating support for file locking and the MOUNT protocol. In addition, support for strong security (and its negotiation), COMPOUND operations, client caching, and internationalization has been added. Of course, attention has been applied to making NFS version 4 operate well in an Internet environment.

RFC 7530 formally obsoletes RFC 3530. This document, together with RFC 7530, replaces RFC 3530 as the definition of the NFS version 4 protocol.

This document specifies the notification mechanism for XCON (centralized conferencing). This mechanism reuses the SIP (Session Initiation Protocol) event package for conference state. Additionally, the notification mechanism includes support for the XCON data model and for partial notifications. [STANDARDS-TRACK]

This document describes the VP8 compressed video data format, together with a discussion of the decoding procedure for the format. This document is not an Internet Standards Track specification; it is published for informational purposes.

This document provides the External Data Representation Standard (XDR) description for Network File System version 4 (NFSv4) minor version 1. [STANDARDS-TRACK]

This document describes the External Data Representation Standard (XDR) protocol as it is currently deployed and accepted. This document obsoletes RFC 1832. [STANDARDS-TRACK]

The Open Mobile Alliance (OMA) is defining the Push-to-talk over Cellular (PoC) service where SIP is the protocol used to establish half-duplex media sessions across different participants, to send instant messages, etc. This document defines a SIP event package to support publication, subscription, and notification of additional capabilities required by the PoC service. This SIP event package is applicable to the PoC service and may not be applicable to the general Internet. This memo provides information for the Internet community.

This document describes a file format suitable for describing directory information or modifications made to directory information. [STANDARDS-TRACK]

XDR is a standard for the description and encoding of data. It is useful for transferring data between different computer architectures. XDR fits into ISO presentation layer, and is roughly analogous in purpose to X.409, ISO Abstract Syntax Notation. The major difference between these two is that XDR uses implicit typing, while X.409 uses explicit typing. This RFC is distributed for information only, it does not establish a Internet standard.

This document defines the standard format for the transmission of mail messages between computers in the UUCP Project. It does not however, address the format for storage of messages on one machine, nor the lower level transport mechanisms used to get the date from one machine to the next. It represents a standard for conformance by hosts in the UUCP zone.

This RFC is a comparison of several data representation standards that are currently in use. The standards discussed are the CCITT X.409 recommendation, the NBS Computer Based Message System (CBMS) standard, DARPA Multimedia Mail system, the Courier remote procedure call protocol, and the SUN Remote Procedure Call package. No proposals in this document are intended as standards for the ARPA-Internet at this time. Rather, it is hoped that a general consensus will emerge as to the appropriate approach to a data representation standard, leading eventually to the adoption of an ARPA-Internet standard.
