In our opinion, the only way to master the technologies in a learning environment, or study the impacts of implementing a network design, is to implement the technology on a real network environment.  We do not support simulators or virtual routers and switches, we use the real things.  This ensures that students and clents experience exactly what they will encounter in their own networks.

We have two lab environments and offer these pictures for reference.

This systems are also available for those studying for certification to use and configure on hourly and daily lease rates.  

The following is an example configuration of the CellStream Lab #1:
