How is rpc implemented

That is, the programmer writes essentially the same code whether the subroutine is local to the executing program, or remote. When the software in question uses object-oriented principles, RPC is called remote invocation or remote method invocation. Note that there are many different often incompatible technologies commonly used to accomplish this.

Message passing. An RPC is initiated by the client, which sends a request message to a known remote server to execute a specified procedure with supplied parameters. The remote server sends a response to the client, and the application continues its process.

There are many variations and subtleties in various implementations, resulting in a variety of different incompatible RPC protocols. While the server is processing the call, the client is blocked it waits until the server has finished processing before resuming execution. An important difference between remote procedure calls and local calls is that remote calls can fail because of unpredictable network problems. Previous Prev. Next Continue.
