An interactive visual protocol simulator

摘要

A flexible protocol simulator is presented that supports interactive visual experimentation with protocols. The simulator is modular and allows ready addition of new protocols. Use of Java permits protocol simulations to be delivered via the web, and also to be developed in an object-oriented manner. A range of simulations is presented, covering link-level protocols to application-oriented protocols. The Trivial File Transfer Protocol is use to illustrate in detail how a protocol simulation is implemented.
