  1. Lightning Talk - 10Gbps EfficiencyApnic Christchurch Roger De Salis - Director

  2. New Fibre Networks in NZ Exists here and now Datalight is building Telephone + Data Centres Fully Meshed Juniper Network Innovative Services on Fibre Low Power Usage (Green!)

  3. 10Gbps • Current Experience for Customers • Lan 100Mbps or 1Gbps (or/+ wireless) • WAN 2-10Mbps (DSL/Frame/Ethernet) • example One Office, via Layer 3. • New Experience for Customers • Lan 100Mbps or 1Gbps (or/+ wireless) • WAN 200Mbps -1Gbps private network • Internet via same channel

  4. Problem - Vendor oversell • If you say to an equipment vendor, customer plans to implement 10Gbps Wavelength backbone, then • “Mr customer - you need big boxes…..” • However:- • Large space and power is not available. • DWDM - 48VDC at 40A • Core Router 2 x 2000W PSU • Edge Router 2 x 1300W PSU • Or you can implement 48V Battery infrastructure!

  5. WAN Example • Dual 10Gbps x N • Dual Diversity • Metro Gbps

  6. There is a better way • 100Gbps (10 x 10Gbps) • Longhaul DWDM 90W • 24 x 10Gb Switch XFP option 5 x Northbound, 5 x Southbound No MPLS code (PE or CE) • 2 x 10Gbps, 4 x SFP, 48x 1GbT • MPLS, VPLS, 4 x 10G, 6 x 1Gbps

  7. Summary 450W vs 5KW-7KW • Careful use of power and space • The Virtuous Circle • Less space = Less Power • Less power = less Cost • less power = longer battery life • less power = less diesel • less power = smaller aircon • etc etc

  8. Next steps • 30W 2 x 1000 Mbps routersMini ITX form factor • You may think what has this got to dowith Network Engineering? • If you can’t control, and actively reduce your coststhen you may not have a network to play with!

  9. IP price pressure
