RPC

RPC

1. protocolo de red

   • permite a un programa de ordenador ejecutar código en otra máquina remota
     • sin tener que preocuparse por las comunicaciones entre ambas.
   • (IPC) mechanism
     • That process can be on the same computer, on the local area network (LAN), or across the Internet.

2. uses other IPC mechanisms

   • Named pipes
     • Named Pipes
     • NetBIOS, or Winsock
       • RPC application
         • Specify the protocol for client server communication
         • Develop the client program
         • Develop the server program

3. DCOM uses the RPC mechanism to transparently send and receive information between COM components

   • on the same network.
     • DCOM is currently implemented only for Windows.

4. How RPC Works?

   • request
     • The thread is blocked from processing until either a reply is received, or it times out
       • the server calls a dispatch routine that performs the requested service
     • The client runtime library then translates the parameters as needed into a standard Network Data Representation (NDR) format for transmission to the server.

5. network protocols supported by RPC

   • TCP
   • Named Pipe
     • 445
   • 135 Endpoint Server any
