Janet Network

Keeping eighteen million users in education and research reliably and securely connected.

Connectivity to rely on

Exchange vast amounts of data in seconds - Janet currently carries three petabytes of data each day.

Whether it's a research-intensive organisation connected at 100Gbits/s or a smaller institution running 1Gbits/s, we monitor usage and manage capacity planning.

Global reach
600+ direct peerings to key education and research network facilities and cloud providers (including Amazon, Microsoft, Google and Apple), key content providers (BBC, Facebook, Netflix, Akamai) as well as supporting international collaborations.

Built-in, world-class cyber security protection - all Janet IP connections are protected by our DDoS mitigation and CSIRT services.

Unparalleled power and access

We're with you, every gigabit of the way. Find out more about the Janet Network in our video explainer.


Dr Matt Williams, research software engineer, University of Bristol

"It provides a very stable, high speed connection to the cloud providers. If we hadn’t had access to the high-speed Janet Network...we would have to use smaller amounts of data. We wouldn’t be able to do our jobs.”

World-class cyber security

Cyber threats are getting more sophisticated and frequent. Our experts work around the clock to provide cyber security services as standard to Janet Network users. That way, cyber security is fully integrated into your infrastructure and platforms, protecting you, your users and the whole Janet-connected community.

Sector journeys

An agile learning experience for higher education

The Janet Network supports innovative learning and teaching within higher education, underpins collaborations with research partners and enables business efficiencies.

Crucially the Janet Network also enables institutions to improve the student experience with rich learning resources and student wellbeing services that help students stay on track and achieve their potential.

It provides students with an agile learning experience, allowing them to roam at will across campus and onsite accommodation using single sign-on on their own devices.

Whether students want to game or use Netflix for work or play, the Janet Network gives them the huge amounts of bandwidth they need, so they enjoy a high-quality streaming experience with no delays. And, as the power behind our learning analytics service, the network allows tutors and mentors to spot struggling students and to intervene before problems escalate.

This infrastructure allows the sector to plan for continued engagement with their research partners and commerce.

Critical infrastructure for further education

As critical infrastructure and as the gateway to a range of Jisc services for education, the Janet Network allows colleges to give students richer learning experiences.

We recently benefited from a Janet Network upgrade as part of the Janet access programme. The improved bandwidth and reliability we’ve experienced since having our new link is broadening our options for teaching, learning and pastoral support in the future.

Aiding collaborative working for research

The Janet Network is the UK’s national research and education network (NREN). It’s also Europe’s busiest.

Open science and big data are placing increasingly larger demands on our network. We’re investing to ensure network reliability and to maintain robust access management mechanisms so that network users can work collaboratively, exchanging huge quantities of highly sensitive data and carrying out complex computations in real-time in the cloud.

We’re currently moving four terabytes of data from Australia to Armagh. To be able to transfer the data across networks is infinitely better and the links are always improving. With the Janet Network we are on a one-gig network and from next year we’ll be upgrading that.

Ciaran Magee, ICT manager at Armagh Observatory and Planetarium

Reliable connectivity across the globe

The UK is the second largest provider of transnational education (TNE), and it contributes more than £500m to the UK economy each year. Janet is the UK's national research and education network (NREN)

The Janet Network’s cost-effective and reliable connectivity makes much of it happen. Providers of TNE need to give their students overseas a learning experience that’s just as good as the ones their UK students enjoy. As part of a global network of NRENs the Janet Network gives you a head start.

Connectivity services for local authorities

The Department for Education funds us to support provision of Janet services to schools in England. This funding agreement means regional broadband consortia (RBC) or tier-1 local authorities (LA) in England can take advantage of connectivity services by being connected to the Janet Network. This includes Janet IP connection, allowing them:

  • Secure and seamless internet access across locations and devices
  • High capacity, direct peering to services such as Apple, Google, Microsoft, Netflix and Dropbox
  • Cyber security monitoring by CSIRT and inbuilt DDoS mitigation

How astronomers are making the universe feel smaller

Just a few telescopes provide astronomers with much of the data they study to uncover the secrets of the universe. But how do they transfer these large data sets around the globe?


Improving connectivity and experience at Hereward College

As the education world shifts its perspective on prioritising digital learning tools, Hereward College is improving infrastructure to help support students

Dr Steven Newhouse, head of technical services EMBL-EBI

"In addition to providing low-latency high-bandwidth (40Gbs) access to our data across the UK and a worldwide audience...Jisc is also able to provide internal connectivity."
