This document specifies the binding protocols used in conjunction
with ONC RPC Version 2. As a prerequisite, the reader is expected to
be familiar with  and  which describe the ONC RPC Version 2 and
XDR (eXternal Data Representation) protocols.
An RPC service is identified by its RPC program number, version
number, and the transport address where it may be reached. The
transport address, in turn, consists of a network address and a
transport selector. In the case of a service available over TCP/IP
or UDP/IP, the network address will be an IP address, and the
transport selector will be a TCP or UDP port number.
A client program needs to know the RPC program number, version
number, and the transport address corresponding to a service in order
to utilize the service. Of these, the RPC program number and version
number are usually built into the client program, as part of the
service definition. The network address component of the transport
address is usually available in a name service, or is given as a...
