The aim of The Computer Network Laboratory is to educate about the bases of constructing local and remote computer networks as well as the advanced ATM (Asynchronous Transfer Mode) nets.
The basic course consists of:
topology, construction and wiring of the network and its components: repeaters, bridges,
switches and routers,
routing techniques,
virtual network construction.
The advanced course includes the interaction of standard computer networks and the ATM nets. It consists of:
local network emulation,
ATM network signaling,
managing of ATM switches,
QoS - Quality of Service,
models of cooperation between IP and ATM networks.
