What is RPC? Higher level mechanism supporting the construction of distributed applications (see also discussion on transparency later) Supports the calling of a procedure in a separate address space (process) as if it exists in the local address space; the process may or may not be on the same machine But what is the semantics of a local procedure call? Adv. Dist. Systems G. Blair/ F. Taiani 12
Styles of RPC First class RPC Integrated into the language => normal language mechanisms can be used for exceptions etc Examples include Java RMI, Ada and Argus Second Class RPC A special Interface Definition Language (IDL) is used to define communications (see later) Language independence Examples include Sun RPC, CORBA and DCE Adv.
