A talk from our Tech 2 tech event, by Gary Blake, network services project lead, Jisc

1. Building the Janet Access Infrastructure16th July 2018

2. The Mission
»To get from here

Aims:
» Reduce costs
» Technical coherence
» Further improve reliability
» Meet user requirements (now & future)

3. Access Programme:The building blocks
Fibre Dynamic Purchasing System
› SSET; Surf ;VMB, CityFibre
› Colt to sign the agreement
Ciena equipment agreement for metro optical & Ethernet equipment
› Purchasing framework in place
› Worked with Ciena in their lab on setup and resilience scenarios
› First order to be placed for Janet lab equipment
Openreach product onboarding
› Process complete allowing us to purchase: EAD, OSA, FC, CableLink, Exchange co-
location facilities 3

4. Access Programme:The building blocks
»Ciena 5170 & Ciena 8700
Regional Aggregation or 100G NTE (5170 only)
i.e. in the co-location PoPs and RNEPs
»» Ciena 6500 when capacity exceeds 5170/8700
Same device as used on the backbone
» » Ciena 3903 / 3928 NTE (customer premises)

7. The first regions to transition
South
› Mini competition on the fibre DPS completed
› Contract not awarded – working directly with
incumbent (SSET)
› Aiming for hybrid fibre & Openreach
South West
› Mini competition on the fibre DPS completed
› Contract not awarded – working directly with
incumbent (SURF)

9. Practical Implications
» As with any other network refresh you will receive a brand new connection – details of
which will be outlined in a new Declaration Letter (Connection Agreement) which will
be sent out to you
» You will need to follow the instructions on this Declaration Letter and you may have to
sign and return this letter to us (if there are charges applicable to you)
» Accompanying this letter will be an information sheet which will outline the service
parameters
» You will have to complete JCUR forms (online) to allow us to build workflows and
records on our database
» If any circumstances have changed (i.e. personnel or B-end address changes) now is
the time to let us know
» You will be contacted by the supplier to arrange access for surveys and latterly access
to undertake physical installation work of fibre etc. and installation of an NTE

10. Practical Implications
» Jisc will also be providing a device that will need to be connected to the supplier NTE.
» The standard connections process will apply
» Order progress updates – provisioning, AM, project
» Issue Management
» Service Migration

11. Member Planning
» Change control planning
» Operational Changes that may impact the delivery of new Janet connectivity
» Transition issues – local resourcing, equipment, infrastructure, late changes
» Access arrangements
» Managing overlap charges

12. Things to consider…
» Is now a good time to change where Janet connections are delivered?
» Have we setup fail-over or redundancy in a way that make sense?
» What services are we expecting to add in the coming years: Public cloud, Shared
Data Centre etc.
» How do we expect traffic needs to grow, change, shrink in the coming years?
» Does my investment cycle coincide with new higher speed connections?
» Why haven’t we deployed IPv6?
» What applications would you want Jisc to provide as part of the network?
» Will a ResearchTransfer Zone help with traffic?
