1. Next Generation Networking - NGN CHECO September, 2003 Pat Burns, CSU

2. Septyember 2003CHECO - NGN Briefing2 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 (10 12 bps) are possible; 1-40 Gbps easy

3. Septyember 2003CHECO - NGN Briefing3 Need for NGN – Scale Expensive, constrictive bottleneck between LANs, CSU LAN@10 Gbps - WAN@135 Mbps - FRGP LAN@10 Gbps WAN “bottleneck” throttles to 1/60 th LAN capacity 100 GBE LANs emerging (1/600 th 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

4. Septyember 2003CHECO - NGN Briefing4 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 http://wnt.utexas.edu/~danu/ren-2003-02.htmlhttp://wnt.utexas.edu/~danu/ren-2003-02.html

8. Septyember 2003CHECO - NGN Briefing8 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)

9. Septyember 2003CHECO - NGN Briefing9 CWDM Link: CSU - NCAR Two CWDM links w/ co-lo in Longmont 1. CSU – Longmont: PRPA fiber 2. 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!

10. Septyember 2003CHECO - NGN Briefing10 CWDM with 2 Waves (2 ’s) over a single pair of fibers FRGP L3 PoP Movaz - Each = 2.5 Gbps, 2 GBE Qwest OC-3 Cisco - GBE CSU CWDM LGMT CWDM NCAR CWDM To Bldr. County

11. Septyember 2003CHECO - NGN Briefing11 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-month Compare!

12. Septyember 2003CHECO - NGN Briefing12 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

13. Septyember 2003CHECO - NGN Briefing13 Fiber splicing Vans UCB “ice cream” truck CSU ambulance Splicing probably in November

16. Septyember 2003CHECO - NGN Briefing16 CDOT Fiber Project: In Process Link to FRGP in Denver Terminus in Colorado Springs Network design Network topology Passive amplification Equipment specification Operational model Implementation

17. Septyember 2003CHECO - NGN Briefing17 Denver Terminus – Topology Lincoln I-25 I-70 I-225 York FRGP Downing Parker Road CCoD Segments Additional CDOT Segments

18. Septyember 2003CHECO - NGN Briefing18 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 Frank Edlin, comments?

21. Septyember 2003CHECO - NGN Briefing21 To Do Fiber topology Network architecture Equipment selection Routing model Operational model Business model – sharing the costs Governance Refinement over time…

22. Septyember 2003CHECO - NGN Briefing22 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
