Believe me I understand many of those issues with direct experience.
I've even had to deal with UL864 listed networking gear, what a pain!
- The University of Minnesota is more a small sized city, than a typical
- The University at one time to operate it own hospital with ER
- The Twin Cities campus alone is 250+ buildings, 32M raw sqrft, 24M
- The TC campus operate its own a power gird, Steam Plant, Chiller Plant
- Level-3 medical biocontainment facilities, thank god we don't have
level 4 or 5 facilities
- 1200 Security Cameras
- Phone Switch with 45,000 time slots and a 911 PSAP
- Campus Network, 85,000 ports of GigE, providing Internet Access,
SCADA, HIPPA, PCI, Security Video, etc...
Connectivity to the Internet is only one small part of the Universities
network, it is just the most obvious to most people, the other parts are
mostly unseen on a day to day basis.
While I agree that a PA only world will not work, neither will a PI for
everyone world, at least for the Big-I Internet. For the Big-I Internet
to work, at least right now, we we need aggregation. However, many, if
not most, of the things you mention don't actually need to be part of
the Big-I Internet's addressing plan, at least the mission critical
function of those items. Maybe the outside wrapper for the VPN that
these might be running over part of the Big-I's infrastructure need to
be part of the Big-I's addressing scheme.
So, please read the other thread I started.
