1.6.1 General Service Process Overview
Concept Analogy
A router is a device that searches for paths to transmit IP packets on the Internet. The router
functions as a post office. IP packets are to the router as mails to the post office. The core
function of a router is addressing and forwarding.
A post office must meet the following conditions before mails can be properly delivered:

Has a mail collection center that collects all mails.

Has a mail query and distribution center that queries addresses of the mails and
distributes these mails to their addresses.
A mail collection center, similar to the data plane on a router, delivers mails. A mail query and
distribution center, similar to the control plane on the router, searches for paths and forwards
mails along the paths to various addresses.
