  2. Technical Advantages • Long term technical goal of BRAN to access central offices • Eliminates last mile costs • Increases flexibility • Increases vendor competition • Virtually unlimited access to bandwidth on dark fiber • Very flexible configuration to meet constituent WAN networking needs • Expands BRAN to the national fiber infrastructure • Long term growth potential

  3. Cost Advantages • Extremely cost effective • NCAR/DOC/City currently have an OC3 to Denver for our WAN connectivity (155Mbps) • 5,745.81/month; $68,949.72; $482,648.04/7 years • This bandwidth is inadequate • We will have to upgrade to an OC12 in the next couple of months • $10K/month for a leased OC12 to Denver; $120,000/year; $840,000/7 years • We would pay $1,675.58/mo for a pair of fibers from the ICG CO in Boulder to the FRGP • $20,106.96/year; $140,748.72/7 years • This saves these partners $699,251.28 at a minimum over 7 years • An OC12 would not last us 7 years, so the savings is really greater. • This does not include CU-Boulder savings

  4. Overall Advantages • Increasing capacity is relatively easy, cost effective and fast: • Cisco 6509 Ethernet switches can support 1Gbps (1000Mbps) and 10Gbps (10,000Mbps) • We already have the hardware since it is used in the LAN • In order to get the the 10 times increase in capacity to 10Gbps, we only have to buy a card for the 6509 switches at each end • We don't have to pay to install a new expensive recurring cost circuit - we already have the fiber • This scales beyond 10Gbps - once we have the fiber, we can continue to grow the network as needed

  5. Overall Advantages • This provides the necessary dark fiber access national networks such as LightRail/Teragrid/etc. • This allows a reduction in service costs for existing services for all BRAN partners since we eliminate the distance charge to the Boulder CO by using BRAN • This was a long time goal of BRAN • Provide faster access to the FRGP and the services there: Commodity Internet, Abilene, intra-FRGP, and future services
