Example: Simulating a Transmission Channel
==========================================

This example network demonstrates how queueing components can be combined to
simulate a point-to-point link with a finite bit rate. (This is only interesting
as a demonstration of the power of the queueing library, network links are never
actually simulated like this in OMNeT++ or INET.)

The network features two hosts (``ExampleHost``) communicating. The hosts are
connected by a cable module (``ExampleCable``) which adds delay to the connection.
Each host contains a packet source and a packet sink application, connected to
the network level by an interface module (``ExampleInterface``).
