Transcript of Janet6 online briefing 5 July 2012
1. Scope, requirements and procurements strategy: Jeremy Sharp 2. Design: Rob Evans 3. Procurement & rollout: Neil Shewry 4. Questions and Answers session
Topics
Janet6: Requirements
Janet customer requirements • Bandwidth • Reliable service delivery • Support for Partnerships • Off-net support • Management of costs
Meeting government strategy • Aggregation of demand • Re-use outside education
and research sectors • Use of open standards
• Janet6 scope “The scope of the Janet6 programme is the replacement of the present contract for the Janet backbone with new arrangements that will remain fit for purpose for a minimum of five years from this time; and the upgrading of regional networks connected to the backbone.”
• Janet6 objectives – A highly reliable network – Flexible in meeting future demand – More agile in dealing with change – Increased range of partnerships and collaboration – Increased level of cost control
Scope & objectives of Janet6
• Bandwidth • Ability to meet ‘commodity’ & ‘data
bonanza’ demands • Reliable service delivery
• Access links: funding not operational issue
• Support for third-party service providers
• Support for partnerships • Across public and private sectors • Technical standards (PSN) & policies
• Off-net support
• Access to Janet from anywhere
Requirements to services
Backbone procurement strategy
• Options appraisal • Procure dark fibre infrastructure • Procure optical transmission equipment • Management in-house by the Janet NOC
• Why? Agility • Janet NOC will have a view from the fibre up the stack to the routers • Fewer contract/administrative boundaries or chains to cross • Directly translate the community’s requirements into engineering
• Why? Different contractual vehicles for fibre and equipment • Fibre: long-term, little need to change • Optical equipment: rapidly evolving, highly competitive
""
competitive dialogue procedure
• Similar topology to SJ5. • Two north-south paths • New east-west path from
Birmingham to Nottingham – Erdington to Lowdham
• No backbone PoP at Reading – Still have a regional PoP
• New PoP in Acton, West London
Janet6: Backbone Resilience
• Contractual – Favourable: Mandated 40Gbit/s in 2006 contract – Favourable: Worked with Verizon for deployment of 100GE – Less Favourable: Maximum bandwidth available for use on each link
• Increasing those needed technical and legal negotiations
• Engineering – Legacy of layered optical systems
• Provide 40G SDH and 100GE over system not designed for it • Large “guard bands” of wasted bandwidth
Limits of SuperJANET5
• Manage the optical layer directly • For more detail see Networkshop presentation
– ROADM • Flexible optical platform
– 100Gbit/s per lambda from day 1 – Plans for 400Gbit/s and 1Tbit/s with better spectral density
• “Data DelugeBonanza” – Big Science
• LHC, SKA, Bioinformatics, ITER, Radio Astronomy, Climate Data – Day-to-day usage
Removing SJ5’s limits
• Original 2006 T-640 chassis still in service – 40Gbit/s per slot, 32 10Gbit/s ports per chassis
• Most upgraded to T-1600 – Same chassis, new switching fabric and PSUs – 100Gbit/s per slot
• T-4000 – Same chassis, new switching fabric and PSUs – 240Gbit/s per slot, 192 10Gbit/s ports per chassis – Two power supplied for resilience
• Each one takes 6, 60A, 48VDC feeds – 17kVA!
• Migration – Janet6 will be in new PoPs – Can’t move all the connections overnight – New routers and hand back the old
Janet6 IP Platform
• Investigated provisioning over optical platform – Not enough competitive offers for smaller chassis
• Investigated merging Lightpath and IP platforms – IP platforms are already short on chassis space, some locations would
require additional chassis • Keep on current MX960 platforms
– Upgrade interconnects to 100GE – Move 10GE lightpaths from lambdas to EoMPLS circuits
• Scope for point to point circuits without committed bandwidth – Shared with Janet IP access
Janet6 Lightpath Network
