  1. Request/Reply Communication Aravind Venkataraman

  2. Concept Interprocess Communication Shared MemoryRequest/Reply Communication Message Passing Remote Procedure Call

  3. Topics of Discussion • Request/Reply Communication • Remote Procedure Call (RPC) • RPC Architectural Model • RPC Process • RPC Communication Protocols • RPC Design issues • RPC Architectures/Implementations • RPC Industry Examples

  4. Request/Reply Communication Design Issues • Synchronous vs. Asynchronous • Client-Server vs. P2P • LAN vs. Distributed Environment • Remote Procedure Call

  5. Remote Procedure Call (RPC) [6]

  6. RPC Architecture model [3]

  7. Microsoft RPC[3] – RPCSS (RPC System Service) module

  8. RPC Process [3]

  9. RPC Communication Protocols [5] • Request [R] Protocol • Request Reply [RR] Protocol • Request Reply Acknowledgement [RRA]

  10. RPC Design Issues[1,7] • Compiler – Interface Description Language (IDL), RPCGEN • Parameter passing • Security – Protected RPC

  11. RPC Architectures/Implementations [4] • CORBA (Common Object Request Broker Architecture) • DCOM (Distributed Component Object Model) • Java RMI (Remote Method Invocation) • Web Services (XML-RPC, SOAP, JSON-RPC)

  12. Other RPC Industry Implementations [1] • 1984 - ONC RPC/NFS (Sun Microsystems Inc.) • Early 1990s - DCE RPC (Microsoft) • Late 1990’s – ORPC (Object Oriented Programming Community) • 1997 – DCOM (Microsoft) • 2002 - .NET Remoting (Microsoft) • Doors (Solaris) • ICE (Internet Communications Engine) • DCOP - Desktop Communication Protocol (KDE)

  13. SOAP (Service Oriented Architecture Protocol) [8] • Typical SOAP Request <?xml version="1.0"?> <methodCall> <methodName>examples.getStateName</methodName> <params> <param> <value><i4>40</i4></value> </param> </params> </methodCall> <?xml version="1.0"?> • <methodResponse> • <params> • <param> • <value><string>South Dakota</string></value> • </param> • </params> • </methodResponse> • Typical SOAP Response

  14. Upcoming conferences in Atlanta
