Well the Remote Procedure Call (RPC) has a different concept for accessing network services.

In this instead of accessing remote services by sending and receiving messages, a client gets services by making a local procedure call.

RPC can be characterized as a specific instance of transaction-oriented communication, where:

A transaction consists of a single request and a single response.

A transaction is initiated when a client sends a request and terminated by the server's response.

Marshalling:

Parameters consist of simple types (e.g., integers) and compound types (e.g., C structures or Pascal records).

Parameters must be marshalled into a standard representation.

Each type has its own representation, the types of the various parameters must be known to the modules that actually do the conversion.

For example, 4 bytes of characters would be uninterpreted, while a 4-byte integer may need to the order of its bytes reversed.
