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

UKERNA objectives

“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.”

Advancing and supporting the UK’s education and research network

What is JANET?

• 19 regional networks.

• 10Gb core across UK.

• >20Gb external connectivity.

• ≈1,000 sites.

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.

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

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.

Challenges…

• Connection of Adult Community Learning community.

• Connection of schools.

Education networks

10 regional networks144 local education authority networks

Scottish Schools Digital Network– built over SuperJANET in Scotland– 32 local authority networksLifelong Learning Network Wales – attached to SuperJANET in Cardiff– 22 unitary authority networks

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

requirements to be served

From requirements to solution

• UKERNA ability quickly to change configuration of network when needed

• configure parallel purpose-built networks via control at transmission-level

• UKERNA control of costs of adding large amounts of bandwidth when needed

• minimise single points of failure• reduce components and complexity

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 effort & resource

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)
