Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Open Network Computing Remote Procedure Call (ONC RPC) is a widely deployed remote procedure call system. ONC was originally developed by Sun Microsystems as part of their Network File System project, and is sometimes referred to as Sun ONC or Sun RPC. ONC is considered "lean and mean", but has limited appeal as a generalized RPC system for WANs or heterogeneous environments. Systems such as DCE, CORBA and SOAP are generally used in this wider role. ONC is based on calling conventions used in Unix and the C programming language. It serializes data using the XDR, which has also found some use to encode and decode data in files that are to be accessed on more than one platform. ONC then delivers the XDR payload using either UDP or TCP. Access to RPC services on a machine are provided via a port mapper that listens for queries on a well-known port (number 111) over UDP and TCP.
