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


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


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

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 –

FTTH Southern Crossroads

(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


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


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)


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


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

Connection to Pueblo, Arkansas Valley?

Jerry Wilson, Ken Goodwin, Dan Tacker – comments?


To Do Fiber topology Network architecture Equipment selection Routing model Operational model Business model – sharing the costs Governance Refinement over time…


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
