Web site:



Pete started out as a PhD mathematician teaching college classes, only to eventually discover he likes computers better. He worked for Terry Slattery coding part of the CIsco IOS CLI interpreter, which grew into teaching network classes and consulting. He has been a CCIE for over 20 years, authored or designed several Cisco courses, while designing networks big and small. Pete is deeply interested in R&S, is getting over MPLS, loves doing network design, application troubleshooting, and is now learning all he can about various datacenter technologies.

Pete blogs whenever he can find time. His blog can be found at

He is on LinkedIn and intends to be more active there.
