I need (for my faculty graduated work) dynamic simulation with a great deal of details, which describes how lower protocols functioning (v35, v90 with modem, after that PPP... and than IP), which way AD-DA conversion is made, how multiplexing, demultiplexing, routing is done, simply whole detailed path of datas, from my home host through telephone officies to PPP, ISP and internet world ... I possible hope to find somwhere simulation of just part of it to help me in putting peaces together. I think powerpoint is too simple for that (its purpose is presentation and simplier simulation), I'll have to do it with something like macromedia or even in visual/borland C++.
