Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain routing concepts and protocols, help design and troubleshoot routing in networks, describe routing policies and their economics, and separate transport and logistics senses.

The process of selecting paths for traffic in a network, in computer networks by protocols and tables that direct packets between networks using addressing schemes such as classless inter-domain routing and policies such as hot-potato and cold-potato routing, hierarchical and source routing and carbon-aware routing, and more broadly in transport, logistics and telephone networks; routing balances reachability, cost, performance and policy.

What it is for: Choosing paths through networks.

It can be explain routing concepts and protocols; design and troubleshoot routing; describe routing policies; separate other senses.

Distinguishing features

Path selection

Protocol-based

Policy-influenced

Multi-domain

What it looks like

Not physical; tables, protocols and paths.

How it is recognised

Path selection in a network

Protocol and policy driven

Switching within a single network segment is different
