Presentation Outline
The Square Kilometer Array
RadioTelescope (SKA)
The need for a high speed research
network
Current situation
Envisaged future
Challenges
African Research and Networking Workshop, CERN
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 today’s best
instruments.
A distributed array of antennas.
A software telescope
Economic opportunities

Possible SKA structure in Southern Africa
African Research and Networking Workshop, CERN
Cost of Bandwidth
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
African Research and Networking Workshop, CERN
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

Radio Astronomy in South Africa
HartRAO
only Radio
Astronomy
observatory
in Africa
Key role in
international
VBLI
Shared sky coverage with major observatories at all wavelengths
African Research and Networking Workshop, CERN
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

The Géant Connection (1)
Established in Oct 2004
GRE tunnel through TELKOM SA’s IP network between…
Géant’s London PoP; and
TENET’s 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It will ultimately be superseded by dedicated link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

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
African Research and Networking Workshop, CERN
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
African Research and Networking Workshop, CERN
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

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
African Research and Networking Workshop, CERN
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
African Research and Networking Workshop, CERN
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

Summary
ESTABLISHES LONG TERM CAPABILITY TO
TRANSACT AT THE HIGHER END OF GLOBAL
KNOWLEDGE AND INFORMATION FLOWS
Strong Government support and drive for R&D
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
