• Cloud & datacentre acivities…
Jisc / Janet
• Two companies
– Jisc - now a charity – the holding company
– Jisc Collections and Janet – a wholly owned subsidiary
• Governance
– Universities UK, Guild HE, Association of Colleges (AoC) - 30% each
– Institutional - 10%
• Janet network charge / Jisc subscription model
–
–
–
–
Jisc wrote to all organisations connected to Janet
Charging model changed – commencing this August (14/15)
Details on Jisc web site
Subscription model may change in future…
• Some rationalisation taking place
– See Jisc web site – “Front of House”

Janet 6
• Optical 40/100G
• Long term – 10+ years for fibre leases – options to extend
• Transmission equipment refresh after ~7+ years
• Roadmap to next capacity increment per wavelength (400G ?)
• More flexible optical architecture
• Direct management of optical infrastructure
• Huge capability for additional capacity
• Continued integration & development of Regions
• Majority of “Research intensive” Universities “on-fibre”
• 100G to GEANT
• 700G Total external peering capacity (UK ISPs, bilaterals and IP
commodity)

Janet6 and e-Infrastructure fibre
Janet Network Services
• IP
– v4, v6 – unicast & multicast
• Layer 2
– Set close to MEF definitions (Metro Ethernet Forum)
• Point-to-point ethernet private wires
• VLANs etc.
– Service definitions & costs/charges being developed
– NB – Matching to GEANT services needs care
• “Lightpaths” – committed/uncommitted capacity…
• “Optical”
– 40 & 100G – true optical
– 10G – part of 4*10G multiplexed service
Site connectivity to Janet
• Current Janet policy - provide IP capacity according to need
– Encourage sites to help research groups use the network
– Don’t want “suppressed demand”
• Janet Network inherently very capable
– enormous latent capacity
– does cost money to enable this (and take time)
• light extra 40/100 Gbit/s wavelengths
• Procure extra access circuits
Astronomy community use
• “Lightpaths” to Manchester / Jodrell Bank
– eVLBI work & expres/Nexpres
– Aggregate 4-6Gbit/s over 10G access circcuit
• LOFAR
– Station at Chilbolton
– 10G physical connection
– Connects to Dwingeloo via GEANT & Surfnet
• UK Internal
– Cambridge to Edinburgh 1G – for data transfer
Janet Testbed facilities
• Aurora2 / NDFIS
• SDN overlay

SDN Overlay & connecting “Testbeds”

•
SDNs / Openflow
Desire to collaborate
Broader UK discussions
Maybe 10+ UK Universities interested in some way
Janet will help
– modest Openflow overlay to interconnect/interact
• Research Council funded projects
– TOUCAN – EPSRC Programme Grant
• Bristol, Edinburgh, Lancaster
• £12M (£6M+£6M) – 5 Years
• Photonic – Layer2 – Access (Wireless +??)
– Other smaller individual projects
• Many, many open questions….
– Management, partitioning/delegation….
Requirements & considerations
• Topology
– Richer than at triangle – can we afford more ? – maybe 4 nodes ?
• Management
– Who does it ?
• Janet or a research project – mixed mode ? – scheduled ?
• Slicing / partitioning
– Can this be realised ?
• Delegation of control / management within the partitions
– What are the constraints (if any) ?
• Openflow
– Which version ?
• 1.0 or 1.3 ?
• Legacy compatibility issues with projects such as Ofelia
• Real users & traffic ? – Maybe – Lancaster have achieved this
• Work with research community to refine these
• Acquire 3 or 4 devices and deploy them
–
Operational Autumn ?
Four node topology – Indicative & evolving
• Maybe 2 physical 10G paths per
node
• Others would be VPNs/logical
paths
• Not determined precise
configuration yet

40G / 100G in core
Some answers…
• Enterprise Hardware
– HP 3800 (6)
• 4*10G + 48*1G
– Brocade Netiron 2024C (2)
• 4*10G + 24*1G
– NEC – much too expensive…
• Four node WAN topology - HP
• Four Janet lab systems
– 2 Brocade
– Broader technology &
feature exploration
Controller software and management ?
• HP proprietary
• Open Daylight
– Both HP and Brocade are compatible (we’re told !)
• Stanford flowvisor ?
– Role in slicing / partitioning
– Looks interesting & appropriate (on paper !)
• Much more work to be done here
– Work with community to steer & advise
Janet - e-Infrastructure & Industry
• Outreach with moonshot pilot (AAI)
• Connecting to Janet – Janet Reach
– State aid compliant scheme
– Industry organisation must apply
• Innovative project
• Meet state aid funding proportionalities
– Janet connection value / total project value
• Should be a high-capacity need
– Scheme operating on 2 monthly cycles until around April 2015 (perhaps a
little longer)
Datacentres
• Slough

Procurement & contracting complete
Janet Network provision in progress
Major centre on Janet
Very open - Tenants install their own racks & equipment
• Anchor tenants
– QM, Kings, LSE, UCL, Crick, Sanger
– Open to all
• Strong interest, probably more to come…
Cloud & outsourced services
• Building on brokerage work in past
• Looking a central procurement of cloud “capacity/capability”
• Cost savings through economies of scale ?
• Soliciting requirements – what do people want ?
– Is there a requirement for elastic expansion into commercial capacity ?
– seeking peoples’ views here
• Discussions on “UK Data Architecture” ! Commencing
– Feed into Research Council Workshop next year
• SIGs with major communities represented
– Particle Physics, Astrophysics, Natural Environment Weather & Climnate,
Bioinformatics
• Finish…
