Abstract

A new URL scheme, 'nfs' is defined. It is used to refer to files and

directories on NFS servers using the general URL syntax defined in

RFC 1738, "Uniform Resource Locators (URL)".

This scheme uses the public filehandle and multi-component lookup

[RFC2054, RFC2055] to access server data with a minimum of protocol

overhead.

The NFS protocol provides access to shared filesystems across

networks. It is designed to be machine, operating system, network

architecture, and transport protocol independent. The protocol

currently exists in two versions: version 2 [RFC1094] and version 3

[RFC1813], both built on ONC RPC [RFC1831] at its associated eXternal

Data Representation (XDR) [RFC1832] and Binding Protocol [RFC1833].
