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
