Implementation of Virtual Exercise Module of
an IP router Configuration
A Virtual Environment refers to the use
of integrated technologies with
communication systems to
provide a form of simulation in
an interactive world.
Features of Virtual Lab:
1. Offers much more robust environment
2. Students can access remotely real network devices
3. Students allowed to make errors
Remote experiments are used in:
1. Nano-science
2. Engineering
3. Computer networks & others
The Experimentation module is not
existing in reality but is simulated
But Simulation should match reality
