Transcript State of the Network

State of the Network
As of May 22nd, 2007
What is the point?

We need faster speeds and better quality of
data for:





IPT (IP Telephony)
IPTV (IP Television)
Future technologies (crystal ball is currently in the
shop)
Many buildings are sorely lacking the
infrastructure
We need an unbiased way to prioritize
buildings for overhaul
How are buildings scored?

The building score is the sum of the scores
for each of the following criteria






Equipment
Data Wiring
Data Termination
Voice Wiring
Voice Termination
Communication Room Environment
Equipment


The type of network equipment
Creighton currently has a variety of equipment
running the network




Hubs – Bad! barely capable at data, voice has no chance –
3680 ports @ 3 points/port
3Com switches – Old and failing, capable at data, voice is
unreliable – 3240 ports @ 5 points/port
Cisco 2950 switches – Not scalable, good at data, voice is
no guarantee – 5100 ports @ 7 points/port
Cisco 3750 switches – Scalable, excellent at data, very
capable at voice – 2761 ports @ 10 points/port
Data Wiring/Voice Wiring

This is referencing the wire running from the patch
panel in the Comm Room to the wall plate






Unrated – Suitable only for the lowest grade data (10
mbps), but very well suited to analog voice – 1 point
Cat3 – Also low grade data (10mbps, sometimes 100
mbps), good analog voice – 2 points
Cat5 – Decent data (100mbps), not IPT capable – 5 points
Cat5E – Good data (100mbps, sometimes 1000mbps), the
absolute minimum for IPT – 7 points
Cat6 – Excellent data (1000mbps, 10000mbps with shorter
distances), excellent for IPT – 9 points
Cat6a – Incredible data (10gbps), excellent for IPT – 10
points
Data Termination/
Voice Termination





Termination is how we transition from the raw wire to
a jack that can be plugged into network equipment
Scoring is the same as the wiring scores
Some buildings have disparate wiring and
termination
As a system we expect it to function as the lowest
common denominator
Poor termination is easier to fix than poor wiring
Environment

The communication room is rated
(subjectively) with these things in mind:





Space
Air conditioning
Power conditioning
Dirt
Miscellaneous atrocities against best practices
Any other Criteria being
considered?

There are some that we haven’t fully fleshed
out how to measure, but would like to include




Entire building uplink speed
Wireless coverage
Need
Open to other possible measurements
Worst buildings (Bottom Ten)

Brandeis Hall
Deglman Residence Hall
Heider Residence Hall
Kenefick Residence Hall
Boyne Dental School
Hitchcock
St. Johns Church
Criss I
Gallagher Residence Hall
Old Gym
How are Residence Halls being
served?



Currently, most of the residence halls have
cable modems for their network connection
Davis Square and Opus Hall are on the
Creighton network
In the future we will need to look at bringing
the remaining halls back into the fold

What are the next steps?

Boyne is undergoing a partial rewire (dental clinic area)
We have made the ask ($$$$) to move forward with the Network
Roadmap
Part of that ask is to be able to replace the aging phone switch
serving campus West of the Interstate
In order to replace that switch, the following buildings will need
an overhaul/augmentation
 Cardiac Care Center
 Bio Information Center
 Boyne
 CUMC
As always time and money are key factors to moving forward
Fun Facts







There are approximately 14781 data ports on
campus
This does not include remote locations or any minihubs/switches
It also doesn’t take into account the number of ports
that will have to be added to take on voice
Right now that calculates to 619 24 port switches
At $6700 per switch, that equals about $4,147,300
Using a 6 year replacement cycle, that comes out to
$691,217 per year (maintenance not included)
Almost $2,000,000 to replace the 3Coms and Hubs
