2. The Janet network
› connectivity to the whole of the UK
R&E sector (universal service)
› connectivity to UK and global research
infrastructures
› connectivity to other networks of
interest in the UK and globally
› Engineered to deliver high bandwidth
and availability
2

3. What is Janet for?
» Research and scholarship
» The business of education
» Collateral/aligned areas
› exploiting bandwidth and reliability
e.g. BBC, local and devolved
government PSNs
» not designed for
› commodity business services
› central government use
› use as a public ISP
3

4. Design principles
» Access layer
› connections to customer sites
» Regional infrastructure
› Regional aggregation
» National backbone
› high capacity and scalability
» External and global connections
› account for ~70% of traffic
› hierarchy of use

9. Cybersecurity needs
»Protecting customers against
DDoS
› network visibility
› mitigation engine
»Protecting Janet critical
infrastructure
»Moving to more “secure”
operations
› ISO27001, CAS(T), ISO20000
System turned on: 04/10/2016.
as of 12/01/2017:
› attacks to date: 307
› largest attack: 23.6 Gbit/s
› longest attack: 12 hours
› potential total attack traffic: 66TB
› (un)luckiest customer: 38 attacks
as of 30/03/2017:
› attacks to date: 581 (153 organisations)
› largest attack: 45.9 Gbit/s
› longest attack: 15 hours
› potential total attack traffic: 152TB
› (un)luckiest customer: 54 attacks

10. Requirements gathered for Janet6
Bandwidth
• Flexibility
• Agility
• Cost control
Service delivery
• Delivery of third-party services
• Cloud services
• Reliability & resilience
Partnerships
• public/public, public/private
• Information assurance
Off-net support
• Anytime, anywhere access
• Internationalisation of education
Management of costs
• Funding environment
• Costs of change

11. Changes in the environment
Changes in funding
Higher information
assurance
Use of off-site data centres
for equipment housing
Challenging economic
climate
Cyber security
Outsourcing services
to the Cloud
Open Science & the
importance of data
Implications of Brexit
Increasing
university &
business
collaboration
Redesigning learning
and library spaces
incorporating the use
of technology
Personalised
learning, driving the
gathering & analysis
of large amounts of
(sensitive) data

12. Technology trends
Software Defined Networking (SDN)
› what: a programmable network
› why: faster, automated provisioning
› drivers:
– increased use of cloud services
– off-site datacentres
Network FunctionVirtualisation (NFV)
› what: virtual rather than physical kit
› why: reduce physical component count
› drivers:
– reduce costs, improve availability
– customer demand for services
IPv6
› what: next-gen. Internet Protocol
› why: address space, routing, security
› drivers:
– IPv4 address space exhaustion
– IPv4 security now unfit for purpose
5G
› what: next-gen. mobile networks
› why: capacity, coverage, latency
› drivers:
– Internet ofThings paradigm
– societal expectations of connectivity

13. Telecommunications market trends
UK fibre marketplace
› 2011/12: retrenchment after expansion
prior to 2008 crash
› 2017: little sign of change; some
evidence of restriction of supply
Openreach divestment
› BT short-haul fibre on market Oct 2017
› new access products from telcos?
› opportunities to use fibre ourselves?
Generally:
› marketplace remains poor(er)
UK mobile marketplace: 5G
› small-cell technology
– filling-in poor coverage e.g. on
campus
› programmable SIMs (eSIM)
Optical networking marketplace
› moving from 100 Gbit/s  400 Gbit/s
› greater network functionality
› cheaper low-end options
› options to reduce IP router stock

14. Janet Access Infrastructure developments
Stephen Percival
14

15. Current access infrastructure
» 18 Regional Networks
› Delivering ~1500 Janet connections
› RNs developed autonomously; now
managed by Jisc following in-sourcing
programme, 2010-2015
› Reflect political boundaries
› Individual designs & wide variety of:
– Optical, routing and switching equipment
– Transmission technologies and suppliers
– Contract arrangements
Regional infrastructure
National (UK) backbone
Access circuits
15

16. Future direction
» Overall aim: to reduce complexity of Janet
access infrastructure, including:
› Standardise equipment
› Overarching management platform
› Some estate rationalisation
› More use of fibre
– Including future Openreach products
– Increase self-provisioning
› …and break the cycle of re-procuring
regional network telco contracts every
4-6 years

17. Janet access infrastructure - aims
»Provide architectural coherence across the whole of the network
»Improve availability of the Janet service
»Reduce capital and recurrent costs
»Increase speed of connection provisioning (installation and
upgrade)
»Rationalise the PoP estate, to deliver improved service levels
consistently across all locations
»Reduce procurement and engineering resource requirements
»Consolidate the supply base (reducing number of supply contracts,
length of supply contract chains, frequency of procurement)
17

18. Steps towards new Janet Access Infrastructure
»2017-Q2/3: Procurement for access provisioning strategy
› Competitive dialogue
› Range of approaches invited
› Proposals mainly based around suppliers’ existing network
infrastructures
› Expensive - lacking flexibility & agility around provisioning &
upgrade
› Compared against Jisc build and operate approach (as with Janet6
backbone)
–Self-build better meets overall aims

20. Building new Janet access infrastructure
»Components:
› Regulated Openreach products (EAD, OSA,OSA Filter Connect, DFA, Exchange space)
› Other telco fibre & col-lo: DPS framework (2017-Q4)
› Optical/Ethernet switching equipment, support services: Procure framework (2017-Q4)
› Other transmission requirements: Renew Janet telco framework (summer 2018)
»New access infrastructure introduced as regional network
contractual arrangements expire over next 3-4 years.
