RPC application development

RPC application development

1. develop a system that emulates the functioning of the client/server model

2. creating an RPC application follows two steps

   • specify the protocol for client/server communication
   • develop the client and server program

3. steps for creating the RPC application

   • first step
     • define the interface between the client and server
   • second step
     • create the service procedures specified in the protocol
   • third step
     • compile and run the application

4. interprocess comunication

   • essential part of the client-server model
   • occurs in cumbersome and potentially machine fashions

5. rpc

   • avoids working with sockets
   • how it works
     • services make themselves known to a network of clients through a naming service
       • the service give the clients an address to open a communication channel with the server
         • the server can accept or deny:
           • client requests
           • sendreplies
         • the connection is closed once the remote session is completed
     • transport independent RPC
       • keeps addressing at a symbolic level
     • socket based RPC systems
       • the default network services for a system are defined in /etc/services
         • tehy become available at boot-time

6. a service

   • is a daemon waiting for connection request
