•Jisc / Janet status•Janet6•GriddPP Networking forward look•Test networks•E-Infrastructure & industry – Janet Reach…•Cloud & datacentre comments

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

•Some rationalisation taking place– See Jisc web site – “Front of House”

Janet 6

•Optical 40/100G•Long term – 10+ years for fibre leases•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 of Regions

Janet6 and e-Infrastructure fibre

GridPP Networking forward look

•Paper from GridPP management board– Very helpful – thanks !

•Discussions with Janet operations colleagues to incorporate into planning

Site connectivity to Janet

•Current Janet policy - provide IP capacity according to need•NO special arrangements for any T2 site - all Janet capacity

provided to organisations– some sites have local arrangements permitting PP groups to route traffic

selectively over site connections to Janet

•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

London

•Brunel - *•Imperial - *•QM - *•RHUL - *•UCL - *

•Key: * means connected to Janet fibre

NorthGRID

•Lancaster - *•Liverpool

– NNW fibre, should remain on fibre following regional reprocurement

•Manchester - *•Sheffield

– subject to YHMAN reprocurement

ScotGRID

•Edinburgh (ECDF - ACF) - *•Glasgow - *•Durham

– regional re-procurement - looking into fibre options

SouthGRID

•Birmingham -*•Bristol -*•Cambridge -*•(Culham) -*•Oxford -*•RAL -*•Sussex – Janet fibre to Hove – University has Dark Fibre to

connect

Ones to watch – no specific concerns though

•(Liverpool)•Sheffield•Durham

•NB – not on fibre doesn’t mean poor service !– But, access circuits needed to provide connection– Extra capacity implies eithe rupgrades or additional circuits

Janet Testbed facilities

•Aurora2 / NDFIS•SDN overlay

NDFIS Topology

NDFIS Topology

NPL

Harwell Oxford Campus – Satellite applications

Broader collaboration – NPL & Europe

• SDNs / Openflow• Strong theme at the conference (other talks)• 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

Connecting “Testbeds”

• Maybe 2 physical 10G paths per node

• Others would be VPNs/logical paths

• Not determined precise configuration yet

• NOT Exclusive, but only TOUCAN lead sites shown

SDN Overlay & Aurora2• Janet service components

• Layer 3 (IP)– Tunnels/VPNs

• Layer 2– Janet “Lightpaths”

• Ethernet / MPLS– committed capacity– VPNs – uncommitted capacity -

future• Layer 1

– Optical: whole wavelengths– 40G / 100G in coreLondo

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

•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 ?

– c.f. yesterdays discussions– Is there a requirement for elastic expansion into commercial capacity ?– Very interested in peoples views here
