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

The Targeted Bottom Ten (worst on top)

Brandeis Hall Boyne Dental School Hitchcock St. Johns Church Criss I Old Gym Health Sciences Library-BIC Linn Cardiac Care Center Reinert Alumni Library

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 mini-

hubs/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
