As I’ve mentioned to many people I’m at Keesler AFB in Biloxi, Mississippi attending Air Force Tech Control 7 Level School. Today, we had a lab on ATM (Asynchronous Transfer Mode). The lab was fairly simple in nature and contained four ATM switches and four routers. The problem with the lab? There were four ELANs. Talk about a waste of time. It took the class four hours to get an exercise that would never happen in real life to work as it should. Four ELANs on one backbone is totally insane and it looks like ATM exercises in the future will remain insane.
