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 10 regional networks 144 local education authority 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

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

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

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

41. 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 Flexibility Separability Scalability Reliability

42. 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

43. Procurement options telco. provides bandwidth services telco. provides wavelength services telco. manages fibre UKERNA has control of the transmission UKERNA leases fibre manages it and the transmission UKERNA owns, lights and manages fibre UKERNA effort & resource

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)
