That is to say, two servers a and B, one application is deployed on the server a, and it is desired to call the method provided by the application on the server B, because there is no memory space, it cannot be called directly, and it is necessary to express the semantics of the call and to communicate the data of the call through the network.
The RPC protocol assumes the existence of some transport protocol, such as TCP or UDP, for carrying information data between communication procedures. In the OSI network communication model, RPC spans the transport and application layers. RPC makes it easier to develop applications including network distributed multiprogrammers.
