Networking model

As explained in Rust Servers, Services, and Apps

A networking model is an abstract framework that describes how messages are communicated between senders and receivers across a network.

A networking model describes how messages move between senders and receivers across a network. It frames communication between browsers, mobile apps, backend services, and infrastructure such as databases. section 2.1

It addresses message formats, byte-level transmission, and handling failures when packets do not reach their destination. The OSI model provides seven layers; internet communication is often described with the simpler four-layer TCP/IP model. section 2.1

The TCP/IP model organizes communication into four abstract layers:

• Network access layer section 2.1
• Network layer section 2.1
• Transport layer section 2.1
• Application layer section 2.1

Client request to backend

A web browser or mobile app sends a request to a backend service, while backend services communicate with supporting infrastructure such as databases. The layers complement one another to deliver the message to its receiving process. section 2.1

How Rust Servers, Services, and Apps covers it

How deep it goes

Defines message communication and outlines four TCP/IP layers, while stopping short of detailed layer-by-layer implementation.

Examples

Uses browser-to-backend and backend-to-database communication as concrete examples, supported by a TCP/IP layer diagram.

What it assumes

Assumes familiarity with clients, backend services, and distributed components while introducing the networking model from its communication problem.

What you can do after

Evaluate how internet messages move between client and server processes using the TCP/IP layer structure.

How it connects

Connects clients, backend services, databases, OSI, TCP, IP, and distributed software infrastructure.
