CONCLUSION
The paper describes the computer networks simulator,
which is realized in Java programming language. The
environment enables visually process tracking of data
transport through network devices from source to destination,
as well as, simulation and visualization of process in "real
time" in computer network. Editing computer networks with
arbitrary topologies by using hubs, switches and routers is
enabled. Components are configured using standard Windows
dialog boxes, or using command line interface. The IP
addressing is also supported. Visualization process enables
frame structure and content tracking on different destinations
given topology.
