AARNetAustralia's Academic and Research Network
• A “Not for profit” Carrier owned by the 38 Australian Universities, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Defence Science and Technology Organisation (DSTO).
• Funded by the member Universities, Federal Department of Science and Technology, Federal Department of Education and State Governments.
• Serving 800,000 users across Australian continent.• 30,000 VoIP calls, 300 direct IP video calls and 20-30 multiparty video
conferences calls per day (PSTN bypass).• 10xGbE, 1xGbE, ATM, SS7 and ISDN interconnects to other network
providers nationally and internationally.

AARNet3 National network
• Dark Fibre “Dense Wave-Division Multiplexing” (DWDM) providing:
–32 wavelengths of 10Gbps capacity initially–Supports growth to 64 or more wavelengths of
40Gbps over life of the network

Research Channel Global
• UW effort to expand ResearchChannel (RC) to international peer networks.
• RC is an on-demand and multicast media archive hosted by UW. • Discussions initiated with RC at fall I2 meeting October 2003 to
utilise RC technology and content base to implement RC as an local A3 service.
• RC-Global will build on the success of RC and will utilise emerging Digital Video (DV) and High Definition (HD) standards to support next generation content and network developments.

Uncompressed High Definition Video
• 1920x1080/60i • 1.4 Gigabits per second
• That equates to 1 DVD being transmitted in both directions every 7 seconds
• Or 8.5 DVD's every minute
• First leg of 10 Gigabit SXTransport Link Sydney to Seattle activated and run at 30% capacity for 5 days to support SuperComputing 2004
• That's a lot of DVD equivalents (~40,000)
• Built from “off the shelf” components

The future of Television
Prof. R.L. Koolhaas – Wired Aug 2004
“With the introduction of digital TV, the concept of video or audio footage will become obsolete, replaced by the generic nature of digital files.”

The future of Television: Consequences
• The following are potential consequences:
– Files will be stored and retrieved easily and, furnished with 'metadata', also searched more effectively. The TV station will be a searchable data archive, much like a library.
– Video on demand and bandwidth on demand will create a new balance between what a TV station wants its viewers to look at and what the viewer wants to watch. The TV station will be a content provider rather than a broadcaster only.
– Interactivity will allow a TV station to communicate directly with its viewers, with profound implications for the kind of programs that will be produced. The TV station will be not only the mouth, but also the ears of the nation.
– With the advent of digital cinema, TV and movies will simply be different resolutions of the same material, with profound implications for production, storage and distribution.
– From being a specialised “manufacturer” of TV content, the digital TV station will become the central hub in a network for the production and distribution of moving images, and could take a much more widely defined cultural role.

Consolidating national and international programs
• Portal will provide a guide for local and international programs.
• Portal design needs to accommodate international efforts but have a distinct AARNet/Australian look and feel.
• Members should have direct control for content insert and local scheduling.
• Multicast address allocation should be handled by portal.• Member interest in multicast address allocation (QRNO).• International (US) ResearchChannel delivered via a both
direct multicast and local downsample/transcoded feed of high quality signal. Requires SX transport.

Research Channel Global – Progress to date
• Meetings held between Aus, Brazil, Korea, Spain, Netherlands and US groups to determine the requirements for a global collaboration.
–Showcase for each participants unique science, culture and arts.
–Develop common video standards–Use common streaming standards–Exchange content–Development of content in multiple languages
• Initial work on portal commenced by Brazil. • RC demo of 1.5Gb uncompressed HD performed at APAN.

Past Experiences with CSIRO
• Two large scale astronomical events broadcast to global audience in 2002 & 2003.
–Solar Eclipse from Ceduna 20,000 viewers–Transit of Venus 40,000 viewers
• Size of the internet doubled between events• Telstra streaming infrastructure collapsed under load• Next large event anticipated 80,000 viewers• CSIRO have an ongoing need to broadcast events of this
nature

Requirements - Bandwidth
• Need A3 roll-out completed to support bandwidth requirements.
• A2 switching capacity in ACT insufficient to handle load.• GrangeNet
–Disentangle a segment in the office from Grangenet for A3 testing.
–Do we test using GN or wait for A3 ?

Requirements - Content
• Letter sent to VC's, PVC's and department heads requesting participation (people and content).
• AARNet Web site needs to be updated with Request for participation.
• Working with QuT Creative Industry Precinct to source initial content. Need to personally approach the “Culture Club” members in Canberra (NMA, War Memorial, Screensound) to obtain content.
• US RC Content available. Will be accessible over SX without local storage costs.
• Building blocks need to be purchased for content storage. • Commence recording AARNet staff presentations. • Front end needs to be developed.

Requirements - Storage
• Estimate of storage requirements
• Single uncompressed HD stream consumes 10,251GB per day
• Estimated 30 days of storage at HD bandwidth required over next 12 months ~60TB
• Initial storage sufficient to hold 7 days of HD streaming content is 8TB
• Pre-production temporary storage also required• Where should the archive be located ?

Multicast
• Multicast design needed.
• What fraction of the network tails is allocated to Multicast ? – 400 Mb suggested
• 100Mb Access Grid• 240Mb HD video stream• 60Mb ~8 * 6-10Mb streams
• Where are the RP's located (edge or PoPs) ?

Conventional Revenue sources
• Archive services for large data sets
–GN have determined demand from CSIRO and other GN connected institutions.
• Encrypted (DRM) Streaming services for members to deliver courseware nationally and internationally.
• Consolidation of member streaming efforts to achieve “volume of scale” on infrastructure.
• Hosting of “broadcast” services for organisations (within circle of interest).

Additional revenue sources
• Advertising
–SBS interprogram model• Limited number of “quality” sponsors
– Makes contract management easier– Provides suppliers to the sector with a unique
market demographic– Deals with equipment suppliers could significantly
reduce cost of establishment

Upcoming Events
• SC04 (Nov 6-10)
–Uncompressed HD demo with Uni of Washington. • Hardware spec received • Purchase of base and additional hardware required• HD content for demo required
