RPC takes client/server mode. The requestor is a client, and the service provider is a server. First, the client call process sends a call message with process parameters to the service process, and then waits for the reply message. On the server side, the process stays asleep until the call information arrives. When a call arrives, the server obtains the process parameters, evaluates the result, sends a reply message, and then waits for the next invocation information, and finally, the client invokes the process to receive the reply message, obtains the process result, and then invokes execution to proceed.
