Title: South African National Research Network SANReN


1
South African National Research Network (SANReN)
International workshop on African Research and
Education Networking25-27 September 2005, CERN,
GENEVA

Presentation Outline
  • The Square Kilometer Array RadioTelescope (SKA)
  • The need for a high speed research network
  • Current situation
  • Envisaged future
  • Challenges

3
The SKA
  • Largest and most sensitive radio telescope ever
    built
  • Global initiative from the start
  • Estimated budget 1.5bn
  • Based on new technology to reduce cost and
    increase sensitivity, field of view,
    multi-beaming, frequency range and flexibility
  • 1 million square metres of effective collecting
    area.
  • 100 times more sensitive than todays best
    instruments.
  • A distributed array of antennas.
  • A software telescope
  • Economic opportunities

  • Future of Radio Astronomy and success of SKA bid
    depends on availability of low cost bandwidth for
    optical fibre for data transmission
  • Huge infrastructure in region
  • Bandwidth makes it possible to locate large scale
    science infrastructure in developing world

6
The need for Research Networks in S.A.
  • Enabler for international collaboration
  • Science no longer succeeds in silos
  • Sources of research input globally distributed
    HUGE
  • Able to tackle more challenging problems
  • Research facilities expensive, avoids duplication
  • Allows researchers to spend more time researching

7
GEOSS
8
  • HartRAO only Radio Astronomy observatory in
    Africa
  • Key role in international VBLI

9
Current Research Network in South African
  • TENET is the bandwidth consortium that arranges
    general Internet access for some of these (via
    TELKOM)
  • The TENET family
  • GEN2 agreement with Telkom (approximately half of
    commercial rates)
  • All universities and Universities of Technology
  • Plus U of Lesotho and U of Swaziland
  • HMO, HSRC, MRC, iThemba labs, NLCSA, NRF, HartRAO
    CHE, SAASTA,,
  • More than 600 000 users
  • CSIR, ARC and some other government research labs
    not part of TENET family.
  • Small connection to GEANT through TENET
  • Bandwidth Limited and even at half commercial
    rates expensive

11
The Géant Connection (1)
  • Established in Oct 2004
  • GRE tunnel through TELKOM SAs IP network
    between
  • Géants London PoP and
  • TENETs International Gateway in Cape Town
  • Provisional in that
  • it shares long-haul bandwidth with general
    Internet traffic
  • It will ultimately be superseded by dedicated
    link
  • Traffic flow is small, but growing fast
  • Great feel good impact on research community

12
Future Research network in SA
  • SANReN The SA Government is creating an NREN
  • Department of Science and Technology (DST)
  • Driven by needs of big e-science projects
  • SALT, VLBI, SKA, HESS, ALICE Project, NBN, GBIF,
    GEOSS, SAEON,HPCC, NLCSA
  • Strengthen links to Géant
  • Will not provide general Internet access
  • All TENET institutions will connect, either
    directly or via a SANReN/TENET gateway
  • First phase in place by early 2006
  • Dedicated connection to Géant (1 Gb/s going to
    10Gb/s)
  • TENET is project Manager for DST

13
Benefits of SANReN for South Africa (1)
  • Leverages global resources and programmes for SA
    Scientists
  • High speed connectivity to over 3000 research
    institutions worldwide
  • Enables access to huge amounts of information
    from primary research facilities around the world
    e.g High Energy Physics, e-VLBI, Human Genome,
    EO data
  • Continued Participation of SA researchers in
    cutting edge science and innovation

14
Benefits of SANReN for South Africa (2)
  • Makes the establishment of large scale science
    infrastructure like the SKA in South Africa more
    attractive
  • Enables better and wider use of expensive
    infrastructure
  • Provides a platform for innovation
  • Enhances SA reputation as a science destination

15
Probable SANReN design
  • SANReN PoPs
  • Johannesburg
  • Durban
  • Port Elizabeth
  • Bloemfontein
  • Cape Town
  • Limpopo Province
  • Architecture
  • 10 Gb/s backbone
  • Up to 10 Gb/s connections to sites
  • International Connection through SAT3 or EASSy
  • Support IPv4 and 6

16
  • Sites
  • 10 sites including TENET gateway will connect in
    phase 1
  • Further 10 in phase 2
  • Additional sites thereafter
  • Deployment model will depend on final outcome of
    negotiations
  • Leasing, IRU, ownership

17
Challenges
  • Challenge 1 Long-haul connectivity
  • Challenge 2 Terrestrial infrastructure
  • Challenge 3 Market structure in SA
  • Establishment of differential regime for research
    and academic networks to be provided for
  • Licensing of private research and academic
    networks
  • Pricing for bandwidth which is available for
    research and academic purposes on existing
    networks
  • Interconnection

18
The University of Witwatersrand
  • 11.3 Mb/s Internet access

19
Summary
  • ESTABLISHES LONG TERM CAPABILITY TO TRANSACT AT
    THE HIGHER END OF GLOBAL KNOWLEDGE AND
    INFORMATION FLOWS
  • Strong Government support and drive for RD
  • SANREN will establish 10Gb network with
    connecting all research institutions into GEANT
  • Will carry research traffic
  • Negotiations at advanced stage
  • Government commitment to use legislative and
    regulatory options to reduce cost of research
    bandwidth
