I-WIRE Background • State Funded Dark Fiber Optical Infrastructure to support Networking and Applications I-WIRE Background • State Funded Dark Fiber Optical Infrastructure to support Networking and Applications Research UIC NU / Starlight Star Tap ANL IIT UC • $7. 5 M Total Funding • $4 M FY 00 -01 (in hand) • $2. 5 M FY 02 (approved 1 -June-01) • Additional $0. 5 M in FY 03, FY 04 • Application Driven NCSA/UIUC • Access Grid: Telepresence & Media • Computational Grids: Internet Computing • Data Grids: Information Analysis • New Technologies Proving Ground • Optical Switching • Dense Wave Division Multiplexing • Advanced middleware infrastructure For more information see www. iwire. org

Dark Fiber • Location, location • Metro • Roughly $2 per meter per strand Dark Fiber • Location, location • Metro • Roughly $2 per meter per strand • Lateral challenges • Regional • May require regeneration; regen, reshape, retime (3 R) is expensive! • Wide area • Expensive due to 3 R requirements • Key is location of carrier runs • $100 K-$1 M/month for 2200 mile OC-192 link

Dark Fiber (cont. ) • Key is the one time up front cost for Dark Fiber (cont. ) • Key is the one time up front cost for the purchase of an IRU • Maintenance and management are the buyers problem • Obtain fiber characteristics as soon as possible (SMF vs. NZDSF, OTDR shots) • Rapid provisioning possible allowing more adaptive networks • The fiber industry is immature and underdeveloped, allowing sophisticated customers to negotiate much more attractive deals than would result from a standard RFP pricing exercise.

Indefeasible Right to Use (IRU) Services • Terms 10, 15, 20 yrs • Alternatives Indefeasible Right to Use (IRU) Services • Terms 10, 15, 20 yrs • Alternatives • Long term capital lease • Short term lease • Managed service • Considered as a physical asset which can be re-sold, traded or used a collateral. • Cost can be amortized over lifetime which results in a monthly cost substantially below traditional telecommunication services. • Be sure of contract conditions due to shaky nature of some vendors financial situation.

Dense Wavelength Division Multiplexing • To ring or not to ring (ring vs. mesh) Dense Wavelength Division Multiplexing • To ring or not to ring (ring vs. mesh) • Redundancy (at what cost? ) • Survivability • Protection • Mesh topology benefits • • • Migration, scaling Deployment speed Capacity Utilization Network Restoration Operating Costs • Laser reach-3 R issues and OEO • Large portion of the cost • No standards • Number and spacing of lambdas are design variables • One transponder per wavelength • Beware OC-192/10 Gb. E WAN PHY/10 Gb. E LAN PHY are not all equal

Wavelength Services • OC 48, OC 192 vs. 10 Gb. E • Be sure Wavelength Services • OC 48, OC 192 vs. 10 Gb. E • Be sure of handoff specifications • Management- determine level required • Qwest/Teleglobe/(3)Link Global/Global Crossing service offerings • Benefits • • Lower cost Customer responsible for protection Share cost of electronics-save capital investment Customer empowerment Potential for higher utilization of network Transparency of signal Flexibility

IP Routers and Switches • Interoperability • Which PHY (LAN vs. WAN) interface between IP Routers and Switches • Interoperability • Which PHY (LAN vs. WAN) interface between DWDM and CPE? • $$$ • WAN PHYs tend to be pricey • Is 10 Gb. E really 10, 000 Mb/s, or 9. 3 Gb/s, or maybe 8 Gb/s? • What is the largest individual stream you must support? • Aggregates vs. large streams • Currently no visibility into the optical layer
