Scope, requirements and procurement strategy

Jeremy Sharp

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

Design

Rob Evans

•  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

The “up and to the right” graph

•  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

•  IPv4, IPv6, unicast, multicast… –  How are your IPv6 plans coming?

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
