ONC Remote Procedure Call Implementation Made Transport

Remote Procedure Calls (RPC) provide a high level paradigm which allows distributed applications to communicate with each other. Current implementations of RPC are mostly transport dependent. This paper describes the architecture, design, and implementation of transport independent RPC. Transport independent RPC depends upon three main modules: Transport Layer Interface/STREAMS, Network Selection, and the Name to Address Translation Mechanism. These mechanisms provide a very powerful way to dynamically select suitable transports at run-time. With these mechanisms and with the assistance of an RPC registry service, rpcbind, transport independent RPC implements a logical client to server communication system designed specifically for the support of transport independent distributed applications
