  1. JANET – The UK’s Education and Research Network Tim Kidd Production Services Director UKERNA

  2. Topics • Who and what is JANET? • JANET Services • JANET Developments • Challenges • SuperJANET5

  3. UKERNA: basic facts • UK Education & Research Networking Association • not-for-profit company (limited by guarantee) • operated as a public-sector organisation • headquarters: Oxfordshire • administration, management, customer service, security, development … • around 90 staff • other network operations via University of London

  4. UKERNA objectives Advancing and supporting the UK’s 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.”

  5. Government Funding Joint Information Systems Committee ICT teaching, learning and research Online Information Services Network Infrastructure JANET Funding and Organisation Higher Education Funding Councils Further Education Funding Councils Research Councils

  6. The Dawn of JANET Late 1970’s 1984 Late 1980’s Early 1990’s Early 1991 JANET Born X.25 network Serving 50 Sites @9.6kbit/s X.25 network 2Mbit/s backbone 64kbit/s access 200 sites Research & HE X.25 network 8Mbit/s backbone 2Mbit/s access JANET IP Pilot (over X.25) Within 10 months IP traffic dominated Regional Research Networks

  7. JANET comes of age 1992 1995 Late 1990’s 2001 2006 SuperJANET5 SuperJANET4 10Gbit/s core 155Mbit/s to 2.5Gbit/s Links to MANs Further Education Connected Schools Networks Connected SuperJANET 34Mbit/s & SMDS network SuperJANET II IP over ATM 155Mbit/s & 34Mbit/s Backbone MANs created SuperJANET III General b/w upgrade More MANs created

  8. What is JANET? • 19 regional networks. • 10Gb core across UK. • >20Gb external connectivity. • ≈1,000 sites.

  9. Who Is Allowed To Connect? • Higher Education Institutions • Further Education Colleges • Research Council Establishments • Schools (collectively or individually) • Other organisations where there is clear benefit to HE, FE or RC community.

  10. Current Connections 213 Higher Education 591 Further Education (16+) 40 Research establishments 62 Self funded 74 Local Education Authorities (collections of schools) 980

  11. ACL schools HE/FE Relative sizes of sectors: from funding body statistics on staff & student numbers The JANET community • JANET available to 18M+ users in education • primary and secondary schools • higher and further education • lifelong learning programmes

  19. UKLight • e-science: huge end-to-end data flows • Will this be possible with IP networks? • UKLight project: • End-to-end Gbps bandwidth • Ultimate goal: application-controlled switching of WDM wavelengths • First steps: electrical multiplexing applications proof-of-concept • Early adoptors • Particle Physics - high performance data transfer • Radio Astronomy - very long baseline interferometry (near-real-time data transfer) • Distributed HPC & visualization

  23. Topics • Who and what is JANET? • JANET Services • JANET Developments • Challenges • SuperJANET5

  24. 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.

  25. Challenges… • Connection of Adult Community Learning community. • Connection of schools.

  26. 10 regional networks144 local education authority networks Education networks Scottish Schools Digital Network– built over SuperJANET in Scotland– 32 local authority networks Lifelong Learning Network Wales– attached to SuperJANET in Cardiff– 22 unitary authority networks

  27. 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

  36. Reliability – programmes… • Replace as much microwave as possible. • Back-up links. • Enhance regional infrastructure.

  37. Topics • Who and what is JANET? • JANET Services • JANET Developments • Challenges • SuperJANET5

  38. Reliability improve by building in more resilience Scalability ability to increase bandwidth at controllable cost Separability protection of interests of teaching & learning and research sectors Flexibility responsiveness to additional network service requirements Visibility controlled access to network monitoring and measurement information by end users SuperJANET5 Requirements end-to-end across JANET

  39. requirements to be served network R&D service development commodity use e-science IP production network test-bed(s) test-bed(s) special purpose bandwidth An overall architecture flexible transmission platform

  40. Reliability Scalability Separability Flexibility 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

  41. Key objective … • 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 UKERNA-controlled transmission platform flexible transmission platform

  42. UKERNA effort & resource 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

  43. 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)

  44. RN RN Collector Arc RN Core Network RN RN RN SuperJANET5 transmission

  45. RNO equipment UKERNA equipment typically single campus – aim for building and electricity supply diversity RegionalNetwork RNO premises Connection to a RN

  46. UKERNA Regional Network Core Network IP architecture reductions in: • complexity • cost less time: • to roll outsoftware upgrades • taken for “at risk” periods

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