Network design is a popular listener topic. On today’s Weekly Show, we have two guests from the University of Idaho to talk about their current network design, new ideas and initiatives they’re considering, and a conversation/consultation on how to address their challenges.
The University of Idaho has 12,000 students and 3,000 residents across one main campus and 18 small campuses. As many as 30,000 hosts attach to the network.
We dive into current network design issues, including around firewalling and microsegmentation, identity management in the wireless network, and a home-grown network management system.
Our guests are Brian Jemes, Network Manager; and Mike Rusca, Network Engineer, both at the University of Idaho.

Good podcast. I like the concept. Any chance that in the next going to touch on the addressing front? It’s been a while, but are dorm network drops allocated public address space that is accessible from the Internet?
I’m thinking that micro-segmentation was used where the term segmentation should have been used. Segmentation is using VLANs and allowing policy to be applied at the L3 interface. Micro-segmentation is the capability to segment within a segment, such as within a VLAN. Policy is applied at the host (VM?) or switchport (campus) to apply policy at that level. I have successfully at a previous gig tested preventing hosts from talking to each other on the switchport level using SGT/TrustSec.
I think I heard in the podcast that the diagram of the University network would be shared in the show notes. Any chance that can be done? Thanks!
How are you gonna invite someone to do the show with you and keep insinuating that they are not good at their job? I want to hear how they made decisions under their circumstances, instead of being on the defensive for half the show.
