UKERNA objectives
Advancing and supporting the UKs education and
research network
  • To take responsibility for the networking
    programme of the education, learning and research
    communities in the United Kingdom and to
    research, develop and provide advanced electronic
    communication facilities for use within these
    communities, and to facilitate the electronic
    connectivity of these communities to external
    third parties.

25
Services challenges
  • Change in community.
  • Increasing demand for services that we have not
    previously provided (e.g.)
  • web mail, filtering and hosting and
  • off-site resolver.
  • Increasing emphasis on security services
  • security health check
  • central e-mail testing and
  • site incident investigation service.

26
Challenges
  • Connection of Adult Community Learning community.
  • Connection of schools.

27
Education networks

28
Challenges
  • Connection of Adult Community Learning community.
  • Connection of schools.
  • Upgrade of FE community.
  • Reliability
  • Change in use of internet by HE and FE
  • Critical to the business

SuperJANET5 Requirements
end-to-end across JANET
40
An overall architecture
flexible transmission platform
41
From requirements to solution
minimise single points of failure reduce
components and complexity
UKERNA control of costs of adding large amounts
of bandwidth when needed
configure parallel purpose-built networks via
control at transmission-level
UKERNA ability quickly to change configuration
of network when needed
42
Key objective
UKERNA-controlled transmission platform
flexible transmission platform
  • visibility to UKERNA in day-to-day operation
  • capacity planning and cost control by UKERNA
  • early adoption of new optical technologies,as
    and when these arrive

43
Procurement options
telco. manages fibre UKERNA has controlof the
transmission
UKERNA leases fibre manages it and the
transmission
telco. provides bandwidth services
UKERNA owns, lights and manages fibre
telco. provides wavelength services
44
Backbone Service Components
  • building block raw bandwidth channels
  • 2.5Gbps / 10Gbps or subdivisions (e.g. 1G
    Ethernet / 155Mbps) 40Gbps in the future
  • IP production service built over channels
  • other services also built over separate channels
  • e.g. high-capacity bandwidth channels Regional
    Network/Regional Network or RNO/international
    (UKLight integration)

47
IP architecture
  • reductions in
  • complexity
  • cost
  • less time
  • to roll outsoftware upgrades
  • taken for at risk periods

Conclusion
  • JANETs community is growing and providing new
    challenges.
  • SuperJANET5 will prepare us for the next stage of
    growth in JANET.
  • Theres lots going on!
