Future Internet Research

•  Study real systems in a real network •  Simulation has limits •  Reproducible experiment

•  Routing •  New protocols/approaches •  Non-commercial routers

•  Measurement •  Platform for “clean-slate”

Next-Generation R & D •  US GENI/FIND & EU FIRE Programmes –

explore ideas for future internet •  See Andrew Moore’s talk later this afternoon


Measurement & Monitoring


Research access to JANET traffic data

•  JANET(UK) – framework and policy for access to JANET traffic data •  Ensure compliance with Law

•  Regulation of Investigatory Powers Act (RIPA) •  Data Protection Act (DPA)

•  Contract with researchers •  Describes work to be undertaken •  How data will be handled & stored

•  MASTS project is the first to use this


JANET Netsight2 •  New system

•  Gather reporting data •  Extensible architecture •  Fine grained access control

•  Access for researchers could also provide basic traffic volume information

•  See Mark Lees’ & Andrew Moore’s presentations later this afternoon


JANET Aurora

What is JANET Aurora ? •  A dark fibre network to support

research on Photonics and Optical Networks and systems •  Dark Fibre network •  Two phases

•  1) Accepted infrastructure Dec 2007 •  2) Being deployed, aiming to accept in the

next few weeks


What is dark fibre ? •  Standard circuits from telcos

•  They have fibre networks with their own equipment and they sell circuits

•  BT, Verizon… •  Dark Fibre

•  Just buy (lease) access to an optical fibre from a telco (in the past they would not sell this & BT still won’t !)

•  Put your own equipment on it to transmit data


Why dark fibre ? •  Photonics Work at this level needs a dedicated fibre

network •  Researchers can put their own equipment on the fibres •  Possibly equipment they have built themselves

•  Investigate new devices & components •  Lasers, Amplifiers, Modulators… •  All the elements to make communication systems work

•  New transmission techniques •  Higher capacity (more bits/s) on each wavelength •  More wavelengths

•  Avoid disrupting other users •  This kind of work can’t generally be done safely on shared

fibres (eg JANET !)

Futures


What’s in the offing ? •  National Grid Service – NGS3

•  Proposed Lightpath links for central resources •  European Grid Infrastructure - EGI

•  Co-ordination between national initiatives •  Not necessarily lightpaths

•  PRACE – EU Supercomputing facility •  May require Lightpaths

•  LOFAR •  Low Frequency Radio Astronomy •  First UK station will be at STFC Chilbolton


High Resolution Media •  Emerging area - UHDV •  JANET Interest •  Community R&D interest •  Likely to spawn Research Council and

EU funded projects •  Will need infrastructure support

•  Lightpaths •  possibly use of JANET Aurora


Campuses •  Almost all the end systems using

JANET exist on campuses •  Accepting/accommodating multiple

services •  Interface LAN – WAN •  Needs to get more attention & study,

both JANET(UK) and Campus

Implications for JANET •  Potential research influences on future direction/s for JANET •  Generally

•  Make the most (capitalise) on the JANET fibre footprint •  Get slicker (technical and policy/procedures) at managing JANET

capacity •  Research requirements

•  Accommodate research projects at all levels on JANET where feasible

•  Net. Measurement – MASTS2 collaboration with JANET ? •  Alien waves

•  Optical transmission dynamics, power & spectrum management •  Dynamic circuits •  Photonics research •  Overlays – short-lived, semi-persistent, permanent •  Beyond point to point circuits ?

•  One to many, many to many (VLANs) •  General e-Infrastrcuture vision
