Announced by Government April 2009
Replaces $4.7B Tender process
$43B estimated cost
Initial injection of $4.7B
Owned by the Government, with Private input
Target date 2017
Fibre to the Home/Premises (FTTH/FTTP)
100 Mbps to 90% of population
12 Mbps to the rest (Wireless + Satellite)
Backhaul Blackspots Initiative $250M
 Competitive backhaul from regional centres
 Inviting organisations to install, keep some, offer rest for community
 Announced April 2009
 Deployment this year

AARNet & the NBN
 Welcome this development
 Collaborate/cooperate
 Immediacy is Key – some Projects require action now!
 Applaud the “Black Spots” Programme
 Regulatory Reform is Vital
 NRENs have different needs

Network Services
 IP Network: 1G & 10G connections
 Dark Fibre
 Wavelengths
 Optical circuits, EN4R
 D-EN4R: dynamic circuit provisioning / “virtual team”
networks – FENRIR

Layered Virtualisation
 Layer3= IP packet level, using standard VPN – multiparty, recognised by IP address, usually secure
(encrypted);
host software aware & implemented.
 Layer2= private Ethernet, NCN – multi-party, plug in at
Ethernet level, host transparent;
implemented in hardware/firmware/combination, in router?
Dynamic setup?
[real Ethernet vs virtual Ethernet].
 Layer1= optical circuit, hard-wired – simulated using
MPLS;
dynamic setup via DCN, Dragon, UCLP, etc.
