Trends in education and research

Uptake of Cloud services»56% of institutions (HE and FE) using public Cloud for email»Office 365 use increasing»69% of institutions (HE and FE) are/have plans to adopt Cloud

services for business applications»Direct peerings with Google and Amazon building steadily »Continuing trend of moving education systems and library

management systems to the Cloud»Off-site datacentre use


Adoption of other business models»An increasing culture of change and innovation in HE and FE» Increasing cross institution collaboration»A growing focus on personalised learning, driving the gathering

and analysis of large amounts of data»A proliferation of open educational resources»Redesigning learning and library spaces incorporating the use of

technology»Streaming and video capture of lectures, and increased online

interaction between students and teaching staff both on and off campus

»Media rich creation and delivery of coursework»Growth of satellite campuses both nationally and internationally» Increasing university and business collaboration2/03/2016 Network Futures

Student experience» Increasing the broader student experience has become a

significant differentiator»Provision of pervasive & high quality wi-fi & support for BYOMD

› Supporting student learning and entertainment requirements


A case study: University XUniversity X : A teaching university that has ssen a 30% annual growth rate on its network. Factors are:» Increased use of rich media, particularly video in teaching

› Sports science uses a lot of HD video› Most video is streamed from external services such as youtube

» Increased use of Wireless› Ever more powerful devices holding increasingly large amounts

of storage› Increased video consumption› Devices auto-synchronising with Cloud services


A case study: University X»Move to the Cloud

› A move to Office365 was completed nearly 2 years ago› Migrating content storage to Microsoft’s OneDrive

»Campus traffic to it’s on-site datacentre is around 10x that of traffic to and from Janet (3Gbit/s vs 300Mbit/s)

» If most services migrated to the Cloud then traffic to Janet would grow tenfold

Radio Astronomy»Radio waves much longer

than light waves»Even large Radio telescopes

have much lower resolution than optical telescopes› eg moon looks 3 x 3 pixels

to a single telescope»BUT – Linking widely spaced

telescopes together recovers the resolution

»Combine signals from telescopes in real time› Long Baseline

Interferometry› Very weak signals – poor

signal to noise› Signal averaging and

correlation› Telescope radio signal =

signal from source + random noise

› Needs very accurate timing»High data rates – 1 to

30Gbit/s2/03/2016 Network Futures

Super High Vision – High resolution media

»BBC trial with NHK for 2012 Olympics» Janet and other NRENs transmit signals over their networks»~300Mbit/s per stream compressed»Super High-Vision is:

› 16 times as many pixels as HDTV› 7680 by 4320 pixels› 22.2 channel sound› 8m wide screen› Amazing!› Immersive

Requirements going into the futureThe requirements boil down to:

»Reliability»Scalability»Flexibility»Security»Reachability

Bigger bandwidth building blocks» Janet was one of the first networks, globally, to deploy 40Gbit/s

and 100Gbit/s technology»On the backbone we use 100Gbit/s building blocks»What next:

› 200Gbit/s› 400Gbit/s› 1Tbit/s


Preparing for the futureWhere do I send this packet!

Addressing


Sept 2015 – ARIN runs out of IPv4 completely


April 2011 – first? Major IPv4 acquisition


Preparing for the futureI want this capacity between A and B and I want it now!

A more agile and dynamic network

»Different network architecture› Central ‘brain’ allowing

network to be programmed› Leading to more agility› Particularly around capacity

provisioning

Software Define Networking


Preparing for the futureMobile amazement..

The (near?) future promises… »Games and New experiences

› Play a virtual game with a friend across the world› Visit a fancy beach whilst stuck in you house

»Self-driving cars»Remote Health-care

› Doctors conducting procedures remotely using robots»Videoconference like you’re really there»Lightening like web speeds
