Revving up With ATM

摘要

It's easier to apologize than ask permission." Put it in a script and it's a great line for a Hollywood tough guy. Hear it from electrician John Sego and it explains why he's the man behind one of the largest ATM networks in the nation. He may not be on the silver screen, but he's proof that even in real life shooting first and saving the questions for later is sometimes the best way to get the job done. Consider the situation at Rolls-Royce Allison (Indianapolis). Five years ago the aerospace engineering company was making do with coax LANs creaking along at speeds as low as 9.6 kbit/s. Three years ago it didn't have e-mail. Now it has an ATM network that boasts more than 8,000 Ethernet ports and 760 OC3 (155-Mbit/s) ports, spans two campuses and 3.7 million square feet of industrial space, and comprises 10 emulated LANs linked by a 155-Mbit/s network that features more than 6,000 switched Ethernet connections.
