Next Generation Networking - NGN
CHECOSeptember, 2003Pat Burns, CSU
Septyember 2003 CHECO - NGN Briefing 2
What is NGN? Optical data networking “Dark” fiber + optical transport
New technology WDM (wave division multiplexing) – multiple “channels” across a single fiber
Much more efficient use of telecom infrastructure, resulted in a “glut” of fiber in the ground
New technology lowers cost and provides dramatically increased performance
NGN ~ $1/Mbps-mo vs. traditional ~ $100/Mbps-mo
Speeds of 1 tera bps – one million-million bits per second (1012 bps) are possible; 1-40 Gbps easy
Septyember 2003 CHECO - NGN Briefing 3
Need for NGN – Scale Expensive, constrictive bottleneck between LANs,
CSU LAN@10 Gbps - WAN@135 Mbps - FRGP LAN@10 Gbps WAN “bottleneck” throttles to 1/60th LAN capacity
100 GBE LANs emerging (1/600th capacity) To provide > modem speeds; e.g. at CSU
WAN speed = 135 Mbps, @ 20k networked devices = ~7 kbps/device (even @4X, still only modem speeds)
To accommodate broadband access from off campus
Each broadband connection can consume ~ 1 Mbps CSU can now accept only about 20-30 such connections
For homeland cybersecurity Alternate path, alternate infrastructure
Septyember 2003 CHECO - NGN Briefing 4
National NGN Activities National Light Rail (NLR)
Initially, CA–WA–Den–Chicago–Pittsburgh Other segments, rings “on the drawing board” Internet2 participation in NLR
Initially, will augment I2 Eventually, will be next generation Internet (I3?)
Puts US on par w/ Canada, Japan, EU countries who are deploying national optical nets
NSF sponsored “Optical Networking Cookbook” See

NGN Activities in Other States California – CENIC Canada – CANARIE Indiana – I-Wire Illinois – I-Wave Mass. – Harvard joint
trench project Michigan – Merit New York - NYSERNet No. Carolina -
NCREN3
Ohio – OARNet Provo, UT & others –

(SoX) SURA (13 states in the
southeast) Virginia tech E-Corridor
Funded by these other states, despite the economy!

Local Fiber Deployments Boulder – BRAN PRPA – Ft. Collins – Longmont CCoD and others Arkansas Valley (SECOM) Glenwood Springs, to Grand Junction? Durango? CDOT activities
Current project: Denver to Colorado Springs
Septyember 2003 CHECO - NGN Briefing 7
NGN Deployments in Colorado
Arkansas Valley Glenwood Springs? NCAR-L3-FRGP Boulder: NCAR, NOAA, UCB,… Ft. Collins: CSU, cities of Ft. Collins
and Loveland, county, K-12, hospital CSU-Longmont-NCAR
Septyember 2003 CHECO - NGN Briefing 8
NGN Deployments - Purpose
Transport for higher education nodes
Have offered to explore mutual back-up with MNT’s OC-3 for transport across the LATA (more later)
Septyember 2003 CHECO - NGN Briefing 9
CWDM Link: CSU - NCAR Two CWDM links w/ co-lo in Longmont
1. CSU – Longmont: PRPA fiber2. Longmont to NCAR: ICG and BRAN fiber
Movaz equipment at all nodes ~ 27-28 dB (~ 50 fiber miles) optical budget
for CWDM Carrier class, simple, inexpensive 2.5 Gbps waves: up to 8 @CWDM, 40 @DWDM CWDM and DWDM possible in the same cabinet Very small company – risk!

NGN Pricing Model for CSU Fiber: CSU-Boulder - $36/mile-mo-pair NGN Coarse (C)WDM equip. @ 1 GBE - $64k Amortization of NGN costs (est.)
Fiber @ 70 miles $2,520/month Equipment $1,000/month (5 yrs.) Total $3,520/month Per unit capacity
@ 1 GBE $3.52/Mbps-month @ 10 GBE ~$0.40/Mbps-month
Current costs for Qwest OC-3 circuit $11,600 per month for 135 Mbps
$86/Mbps-monthCompare!

CDOT Fiber Project The CDOT Project
Conduit - south along I-25 from Lincoln in Denver (TREX) to south Colorado Springs
168 ct. fiber from CDOT headquarters in Denver south along I-25 to Colorado Springs, with 3 “spurs” to Douglas County
Regeneration node w/ generator back-up at Monument Hill The deal:
Funded mostly by CDOT (132 ct.) & Douglas County (24 ct.) Higher ed (12 ct.)
Contributes $50k, splicing labor, and some expertise
Next CDOT project is Colorado Springs to Pueblo
Septyember 2003 CHECO - NGN Briefing 13
Fiber splicing Vans
UCB “ice cream” truck CSU ambulance
Splicing probably in November

Denver Terminus There will be costs associated with the
Denver Terminus – looking for 2 fibers, to start with CDOT wants a “swap”
Maybe pulling in shared fiber, along I-225? Maybe offer them a color of light from CS-Denver? Cost may be significant
CCoD wants the costs of builds covered Costs will probably be minimal
A second path, maybe via I-25, is on our agenda

Equipment Recommendation Recommend considering carrier
class equipment as the link will be very important to multiple entities Reliability – 5 9’s (99.999%) ? Monitoring and alarms CWDM
Routing flexibility Separation of traffic Relatively inexpensive scalability
