Network stack

As explained in Rust Servers, Services, and Apps

A layered collection of networking protocols and supporting implementations that enables communication between distributed system components.

A network stack is the networking layer within a distributed system, connecting distributed application components across servers. It supports communication between workloads running on separate machines while sitting alongside applications and hardware and OS infrastructure. section 1.1

A modern web application uses the stack in this way:

• Distributed applications communicate internally through a range of networking protocols. section 1.1
• HTTP commonly serves as the application-layer protocol for communication with the outside world because it is simple and universal. section 1.1
• Servers may connect within one data center or across geographically distributed cloud infrastructure. section 1.1

How Rust Servers, Services, and Apps covers it

How deep it goes

Defines the stack within a distributed-systems model and identifies HTTP as an application-layer protocol, but does not detail lower layers.

Examples

Uses distributed web applications such as social media, e-commerce, sharing-economy, entertainment, and cloud applications.

What you can do after

Evaluate/understand how distributed web applications place HTTP and server communication within a broader systems stack.

How it connects

Ties distributed applications and HTTP to hardware and OS infrastructure within distributed systems.
