Connecting Texas
Texas higher education has made several starts at organizing a state-wide network since the late ’80s. Distances, funding and technologies have stopped those efforts.
Until now…
![Page 5: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/5.jpg)
On the convergence of great ideas, enormous blunders and able people. In that order.

LEARN Phase 1a
![Page 18: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/18.jpg)
The parts
• IRUs– WilTel(?), AT&T (thanks SURA!)
• Leased lambdas– NLR, Wiltel(?)
• Optronics– Nortel
![Page 19: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/19.jpg)
The End
![Page 20: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/20.jpg)
Creating the Core Network
• Identifying Paths and Media
• Selecting the Optronics
• Funding Ongoing Operations
• Build & Implement Plan
![Page 21: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/21.jpg)
Identifying Paths
• Selection of Endpoints– Population centers?– Major Universities– Where the fiber is?
• Impact of TACC ETF award– Getting to Chicago
• Impact of NLR– Initial focus on Dallas– Focus on Houston (currently)– Connecting El Paso
• SURA – AT&T fiber deal
![Page 22: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/22.jpg)
Texas Backbone Status• Dec 2003
– Bids received for dark fiber– Subcommittee of the LEARN Technical Advisory
Committee (TAC) began review of bids
• Jan 2004– LEARN Board received and adopted recommendation from
TAC • Initially, dark fiber triangle (Hou-CS-Dallas-Austin-SA-Hou) +
lambda to Lubbock.• Expand dark fiber network to South, West, and East Texas
– LEARN Board authorized UT and A&M to proceed with IRU as necessary
![Page 23: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/23.jpg)
![Page 24: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/24.jpg)
Name the Sites
![Page 25: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/25.jpg)
Identifying Media
• Dark Fiber or Leased Lambdas permitted– Geography JUST TOO Large– Time to implement Service
• Allowed shared infrastructure– Carrier Operated Service– Guaranteed lambda quantity
• Not restricted to a single vendor fiber topology
![Page 26: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/26.jpg)
What we GOT
• Traditional Dark Fiber– Vendor Topology Restrictions
• Shared Service (they build/own it; we pay for it)– Two Vendors offered 8 or 16 guaranteed
10Gigabit lambdas to Education
• Leased Lambdas (20 year)
![Page 27: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/27.jpg)
Fiber offerings to Texas
![Page 28: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/28.jpg)
Selected Fiber Path
• Two vendors minimizes costs, maximizes coverage
• Dallas-Austin-San Antonio-Houston
• Dallas-College Station-Houston
• Requires metro interconnects in Dallas, Houston
![Page 29: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/29.jpg)

Selecting the Optronics
• There are fundamentally different kinds of optronics, distinguished by the distance between required signal regeneration.
• Texas’ core needed ~1,300km
• SONET protection was desired as an option, but not mandatory for every service.
![Page 32: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/32.jpg)
Selecting the Optronics (cont)
• Variety of available interfaces generally greater in metro versus long haul.
• Created evaluation for “best value” considering initial implementation AND later growth.
• Who wants “serial number 1” for support of production services?
![Page 33: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/33.jpg)
Funding Ongoing Operations
• Initial (current) decision that O&M must be pay-as-you-go.
• Service-for-fee separate from membership dues.• Leased lambdas treated as capital cost (try not to
penalize geography).• A&M and UT Systems can purchase enough
services for their WANs to ‘cover’ cost of core triangle.
![Page 34: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/34.jpg)
Build & Implement Plan
Coalition warfare!• Engineering by committee can work.• Select one school to do the procurement
paperwork.• Pick a Project Manager for vendor
coordination and status tracking.• Weekly phone/videoconference/face-to-face
meetings.
![Page 35: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/35.jpg)
Build & Implement Plan (cont)
• Activities run in parallel, not one after another:– Long haul fiber and Lambda services– Metro fiber– Optronics selection– Services Definition
• Texas’ target: Spring 2005 for first light.• Planning started for next phase.
![Page 36: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/36.jpg)
Lessons
• Open bidding is almost the only way to determine availability.
• Really hard to design optical transport when you don’t know which vendor, or what you want to do,
“Indecision is the key to flexibility”
• Plan for expansion.
![Page 37: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/37.jpg)
Metro Access Issues
• Current Efforts– Houston– Dallas
• Success Story – Austin– GAATN
![Page 38: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/38.jpg)
Why Metro?
• Driving need is to interconnect the two long haul fiber providers (Dallas, Houston).
• Desire to consider local needs in forming solution.
• ‘Last mile’ may not be part of the backbone, but needs should affect backbone choices.
![Page 39: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/39.jpg)
Houston
• Interconnect effort in Houston benefits from local upgrade effort.
• Area schools have some existing interconnectivity.
• NLR has same (similar) problem.
![Page 40: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/40.jpg)
Current Metro Upgrade Needs• Improved capacity between TMC-Rice-UH for
research projects that can attract federal funding in CS and the Sciences
• Improved capacity to Internet2 to participate in national projects developing national and global information infrastructures or tools for the construction thereof
• Connectivity to the National Lambda Rail and LEARN.
![Page 41: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/41.jpg)
Dark fiber proposal
• Two rings of 12 strands each offered by Abovenet (formerly Metromedia Fiber Networks (MFN)) address the needs for improved capacity between TMC-Rice-UH and between these institutions and the NLR PoPs in Houston
• Improved capacity to Internet2 still to be resolved
![Page 42: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/42.jpg)
Ring-1: TMC-Rice-UH
![Page 43: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/43.jpg)
Ring-2: TMC-Rice-UH-AT&T-WilTel
![Page 44: The National Network of Texas Moderator: Willis Marti Texas A&M University](https://reader036.vdocuments.net/reader036/viewer/2022062714/56649d2c5503460f94a01d46/html5/thumbnails/44.jpg)
Dark Fiber Status• TMC access points to be added in the short
term currently under review by the South East Texas GigaPoP technical reps from TMC institutions
• Build-out at UH under review• Contract issuing initiated by TLC2 for both
rings• Resolution on Internet2 capacity upgrade to
follow asap
