Beginner learning how to build a Router Simulator?

[cristal]

How can I build a router simulator with 4 input and output ports,a routing
processor and the switching fabrics?

Requirements for testing:
- Develop a traffic generator (sender) that accepts strings of ASCII
characters (message), convert them to their binary codes, and encapsulate
them in packets and frames, then forward the frames to the router.
- A receiver should be developed to decapsulate the frames coming out from
the router’s output ports, and convert them to the original ASCII
characters (at least four senders and four receivers are required).
- The router may drop some of the packets, if the traffic exceeds the
router capacity (i.e. queues are fully occupied).

Do you have a C++ _language_ question? If so, ask it. If you need
a general software engineering advice, post to comp.software-eng.
