In order to overcome the problems caused by the undefined format of the current FTP LIST command output, a new command is needed to transfer standardized listing information from Server-FTP to User- FTP. Commands to enable this are defined in this document.
In order to allow consenting clients and servers to interact more freely, a quite basic, and optional, virtual file store structure is defined.
This proposal also extends the FTP protocol to allow character sets other than US-ASCII by allowing the transmission of 8-bit characters and the recommended use of UTF-8 encoding.
Much implemented, but long undocumented, mechanisms to permit restarts of interrupted data transfers in STREAM mode, are also included here.
This document specifies new FTP commands to obtain listings of remote directories in a defined format, and to permit restarts of interrupted data transfers in STREAM mode. It allows character sets other than US-ASCII, and also defines an optional virtual file storage structure,
This document describes a mechanism that can be used by FTP clients and servers to implement security and authentication using the TLS protocol defined by [RFC-2246] and the extensions to the FTP protocol defined by [RFC-2228]. It describes the subset of the extensions that are required and the parameters to be used; discusses some of the policy issues that clients and servers will need to take; considers some of the implications of those policies and discusses some expected behaviours of implementations to allow interoperation. This document is intended to provide TLS support for FTP in a similar way to that provided for SMTP in [RFC-2487].
TLS is not the only mechanism for securing file transfer, however it does offer some of the following positive attributes:
Note that this specification is in accordance with the FTP RFC [RFC- 959] and relies on the TLS protocol [RFC-2246] and the FTP security extensions [RFC-2228].
The transfer of files containing audio/video essence and metadata is a fundamental and important issue. The computer industry has developed several standards which specify methods for performing file transfer. However, there are problems and requirements unique to the video production industry which are not fully addressed by the existing computer industry standards. To overcome these limitations, and in order to guarantee interoperability in the interface, network and protocol domain for file transfer, it is recommended that the industry follow the rules and guidelines defined in this document.
This document presents methods for adapting current computer industry standards and presents a new standard. The use of the ubiquitous File Transfer Protocol (FTP) is described as it relates to transferring large video and audio files. A new file transfer protocol, FTP+, is defined which provides a number of additional functions. FTP+ builds on FTP and uses the same base set of commands as FTP. FTP+ includes new commands that enable additional features and also provide the ability to embrace new network protocols as they become available. This document contains details of these new FTP+ commands.
