Developments in RedIRIS as seen in

the Context of Developments in

other NRENs

http://www.terena.nl/compendium


Conclusions

• RedIRIS is one of the leading NRENs in Europe

• It can be proud of its achievements over the past years

• But…


Structure of talk

• What is TERENA?

• RedIRIS (compared with selected other NRENs)

• Conclusions


• A not-for-profit association of European National Research & Education Networks

• Governed by the General Assembly of the Members, larger members have more votes

• Funded through Membership Fees and project funding

• Secretariat located in Amsterdam, The Netherlands• 14 staff (13 FTE)• 33 National Members• 2 International Members: CERN, ESA• 10 Associate Members (including DANTE,

equipment vendors and telecoms operators)

TERENA Organisation

TERENA’s Mission• Represent common interests and opinions of members

– Make political and industrial contacts

– Lobby European Union and national governments

– Liaise with other continents

• Knowledge Transfer– Conferences, Workshops & Seminars.

– Developing informational, best-practice and training material

• Technical Programme– Developing, testing and promoting new technologies,

services and applications

– Task Forces, Projects and Workshops.

• Fostering new services• Does not run a network! – DANTE does


Task Forces

• Small groups of volunteers working on specific problems.

• Limited duration, typically 2 years.

• Open to any individual or representative offering expertise, manpower, equipment or services.

• Set of defined tasks and deliverables.

• Each task force has its own mailing list & web space.

• TERENA provides organisational and secretarial support.

• http://www.terena.nl/task-forces/

• Under the GN2 project, collaboration between the Joint Research Areas and the Networking Activities and the work of most of the Task forces, but:

– The Task Forces have a mandate that is not limited by the terms of the GN2 project

– The Task Forces are open


Task Forces (cont..)

• TF-NGN (started December 2000)– Tests suitability of new networking technologies for use in

future European backbone, NREN or campus networks.– Mandate expiring, new mandate being discussed.

• TF-CSIRT (started September 2000)– Promotes collaboration and knowledge transfer between

European CSIRTs.– Oversees training workshops for CSIRT staff that are part of

the TRANSITS project



• TF-Mobility (started January 2003)– Evaluate mobile equipment and software.– Evaluate possible authentication and authorisation

techniques (e.g. web-based, 802.1X, VPNs)– Defined an inter-NREN roaming architecture (802.1X

based). EduRoam – 17 countries connected,– Investigate and address security issues.

• TF-VVC (started September 2004)– Advice on setting-up videoconferencing rooms.– Survey national streaming media content.– Develop an announcements portal.– Develop a common metadata model.– Contribute to international dialling and numbering plans.– Establish academic netcasting channel.



• TF-EMC2 (just started)– Stands for European Middleware Coordination and

Collaboration) investigates the development and deployment of middleware infrastructures at campuses and NRENs level and their interoperability issues.

• Chair: Diego López

• TF-PR (started September 2003)– Aims to improve public relations and information

dissemination for research and education networking.– Allows exchange of ideas, experiences and methods.– Operates a server for news exchange.

¡ Hola PAPI !


SERENATE

• Study into European Research and Education Networking as Targeted by eEurope

• EC-funded project led by TERENA: 1 May 2002 - 31 December 2003

• Studied the evolution of networking over the next 5-10 years.

• Produced set of recommendations for future research and education networks in SERENATE countries.

• http://www.serenate.org/


NREN Compendium• Compendium has been published

annually since 2000.• Collection of relevant information about

European NRENs:– Administrative data and legal form.– Number of users and market share.– Internal and external connectivity,

and capacity of links.– Network traffic, load and

congestion indicators.– Services, staffing and funding.

• Provides overview of network status in each country.

• 2004 edition now available on TERENA website,

• A good tool for lobbying governments and/or funding bodies!

http://www.terena.nl/compendium


Other interesting TERENA publications

• IP Telephony Cookbook – basic and advanced services;– regulatory and legal aspects;– interoperability – available as book and online PDF

• Guide to Network Resource Tools

– published since 1996– Aimed at users and support staff– Provides basic introduction to the

Internet– May be freely distributed by

TERENA members, who may also acquire the local translation rights (e.g. Slovenian).

– http://gnrt.terena.nl/


EGEE

• Enabling Grids for E-Science in Europe. • TERENA is the lead dissemination partner:

– Providing web services.– Assisting with PR.– Organising conferences (every six months).

• Next event is in the Hague (NL), November 2004

• Project has many Spanish participants.• http://public.eu-egee.org/


TERENA Networking Conferences

• In a tradition of > 20 years

• Next one will take place in Poznań, Poland, from 6 to 9 June, 2005

• Call for Papers is on the web and has just come from the printers

http://www.terena.nl/tnc2005


Other Projects

… we will save for another time


Warning! Don’t take what will follow too seriously!

• Based on data provided by the NRENs to the Compendium questionnaires

• Differences in interpretation (diminishing)• NRENs are difficult to compare• Leads to more questions than answers…• Will give you data from France,

Germany, Italy, Poland and Spain• (plus some from Portugal and from The

Netherlands)


Topology of the RedIRIS Network, 2001/2002


Final eEurope Benchmarking Report, COM(2002) 62 final of February 2002:


Comparison perhaps not completely fair…

• RedIRIS had 17 connections at 155 Mb/s

• GARR had just upgraded 3 centres to 2.5 Gb, but each via 2 routes, so they claimed to have 5 Gb/s

• Many other centres in Italy in fact connected only at 34 Mb/s (yellow lines)


Today, the situation is very different

Note the redundancy

aren’t they looking at the stars from here?


Other countries: France

Germany

A few things to point out…

Not much change here

Can 2 Mb/s be enough for a University?


Differences between NRENs… e.g.: who gets connected?


Is the funding model relevant for the success of the NREN?

… although diversifying funding sources(e.g. by getting it from various GovernmentDepartments) can be a wise strategy…


Is legal form relevant?


Conclusions

• African saying:

“A pound of feathers

will only fly

if there is a bird inside”


Conclusions

• RedIRIS is indeed one of Europe’s leading NRENs

• Assume ownership of your network!

• Congratulations on your Jornadas Técnicas

• Times ahead are challenging
