  2. Prime Directive Get fiber to all 91 institutions within 5 years

  3. Defining Mission • So what do you want this thing to do? • Reduce long term costs • It appears that long term costs can be contained by making large upfront capital investment • Allow dedicated light paths through regional fabric • Research community believes that Lambda based service provides resource that other mechanisms don’t • Allow interaction with other Gigapops and entities in a dedicated fashion (HOPI?) • Problem inter vendor compatibility

  4. Project Description • 1600 route miles of fiber • 20 year IRU • Phase One Light Backbone • Phase Two Connect all State 4 year Universities • Phase Three Connect Remaining 74 • Phase Four Connect Private Sector with Research Mission

  5. Participants • Higher Ed • K-12 aka Schoolnet • County Governments • City Governments • Ohio Educational Broadcasting

  6. Basics • Built Cisco ONS 15454 • Uses Transponder (G.709) • Resiliency at Layer 3 • Can support 32 Lambdas • Cost ~$17 Million • Almost two years into project • Uses SBC as integrator

  7. General Principles • We used full 15454 implementation • Used the AMP and Muxers that go into 15454 • Makes management uniform • Makes certain aspects of sparing easier • Must support production e.g. can’t go to far out of the box • We over engineered by 4% to 10% for degradation • Accounts for aging fiber (aerial) • Accounts for fiber cuts • Constrained only by fiscal considerations

  8. Current Status • First two rings and three laterals go into production early August • Will bring up in sections • Initially connect to current POPs • Start migrating to direct connects immediately • OSU, Wright State, University of Dayton, Ohio U, Ohio Wesleyan, Shawnee State, Cerf e,g, U of Cincinnati, Xavier, Cincinnati State, Mount Union Hebrew.

  9. Routing Architecture How we addressed the fish problem

  10. Current POP Design I1 I1 ATM I2 ATM I2 ATM I1&I2 POP Campus

  11. Current POP Design I1 I1 ATM I2 ATM I2 ATM I1&I2 POP BGP for Route diff Campus

  12. New Design Goals • Reduce Costs • Reduce Complexity • Reduce Maintenance Fees • Deliver Services

  13. Layer 2/3 Gear • GSR 12410 in core MPLS/IP router P/PE • Juniper M7i CPE e.g. moved most of the intelligence to the edge • Cisco 3750s at POPs and Campuses

  14. MPLS Requirements • CPE device • PE Provider Edge • P Provider Core LSP Switching Router • We can collapse P and PE to one device • Need CPE for Label to IP binding • I1 will be standard routing • I2 will be Label Switched with BGP multihop to find correct path. • Must deliver advanced services to I2 community • IPv6, Multicast, Jumbo Frames etc.

  15. New Architecture CPE PE/P CPE GigE Aggregator GigE POP Campuses

  16. New Architecture MPLS for I2 Routes LFIB IP for I1 Routes FIB Red = LDP tagged CPE PE/P BGP Multihop LDP Exchange with Core CPE BGP Multihop LDP Exchange with Core GigE Aggregator GigE AS600 Campuses AS3112

  17. What Really Matters? • Delivery of Packet Service • Relies on a number of mechanisms • Leverages the Optical, Layer 2 and Layer 3 Domains • Leverages appropriate use of technology to achieve best results at best cost. • End user receives service as if it were a light path.

  18. Unsung Heroes Gene Bassin, Mark Fullmer, Tony Eller,Matt Hakin, Jason McDonald, Chris Spears, Chirstine Dorsey, Greg Steele, Weiping Mandrawa, and Linda Roos.
