  11. 11. Evolution of the Market Telecommunications Liberalisation Slide Relative Costs of Connectivity v Number of Suppliers Monopoly supply = High costs Markets open above 4 Evolution of Market Competitiveness GÉANT Offers 1996 – 2001 Note: LOGARITHMIC SCALE Changes are orders of magnitude Material from SERENATE Report, published TERENA 2003 – Acknowledgements to DANTE
  12. 12. Example – Hybrid Networking <ul><li>Hybrid Networking </li></ul><ul><li>Flexibility of IP core with any-to-any routing </li></ul><ul><li>Large Traffic flows (e.g. Grids, Astronomic Data . . .) by-passes router cloud. Has an End-to-End optical path </li></ul><ul><li>Uses same underlying fibre infrastructure </li></ul>Slide Traditional IP network Flexibility of IP core with any-to-any routing Large Traffic flows must traverse a path through all routers from end-to-end Costs of O-E-O conversion and bottlenecks
  13. 13. Example – Federations Slide Federation University B University A Student Resource
  14. 14. Federated Network Access - eduroam <ul><li>eduroam = roaming for education </li></ul><ul><li>Federation of national eduroam federations </li></ul><ul><li>To provide network access between the institutions connected to eduroam </li></ul><ul><li>Using the same credentials they would use to get on-line at their home institution </li></ul><ul><li>First real test back in 2003 </li></ul><ul><li>As part of a TF-Mobility test </li></ul><ul><li>Since 2005 eduroam is part of GÉANT2 </li></ul>Slide
  15. 15. Other Examples of Benefits <ul><li>NRENs undertake applied research in a way the commercial concerns would find difficult. </li></ul><ul><ul><li>Leads to testbeds, pilot services which lead to new services. </li></ul></ul><ul><li>NRENs stimulate innovation bring forward technological advances . </li></ul><ul><ul><li>These find their way to commercial ISPs and benefit the public at large . </li></ul></ul><ul><li>bring the benefits of collective buying power </li></ul><ul><ul><li>provides savings for the community and the country as a whole </li></ul></ul><ul><ul><li>Internationally this is achieved by DANTE with GÉANT </li></ul></ul>Slide
  16. 16. Most Importantly <ul><li>The independence of NRENs is a valuable asset for advising in the development of national policy on education, research and IT </li></ul><ul><li>NRENs occupy a position of trust in this respect and are called on to provide guidance uninfluenced by the pressures and demands of commercial business </li></ul><ul><li>Many NRENs are recognised as being a pool of expertise that is an asset to its country </li></ul>Slide
  17. 17. Questions may be asked <ul><li>Why is there a need for NRENs when commercial ISPs exist? </li></ul><ul><li>Need for central funding of the NREN, can’t the end users pay the bills themselves? </li></ul><ul><li>The existence of the NREN will distort the Internet market and take away market share? </li></ul><ul><li>Isn’t the NREN operating a public service and should it be regarded as a public operator conforming to the local legislation? </li></ul>Slide
  18. 18. Why is there a need for NRENs when commercial ISPs exist? <ul><li>NRENs are usually not-for-profit organisations that seek to support their community in the best possible way, technically and economically </li></ul><ul><li>Commercial ISPs exist to make a profit </li></ul><ul><li>NRENs are motivated to provide the innovation and new services needed by education and research </li></ul>Slide
  19. 19. Why is there a need for NRENs to receive Government funding? <ul><li>Government support essential to emerging NREN </li></ul><ul><li>Generally, a hybrid funding model may be beneficial </li></ul><ul><li>Government can take the longer term view funding start-up costs, innovation and upgrade. </li></ul>Slide User/Client Funding SHORT TERM horizon Non-User /Client Funding LONG TERM horizon
  20. 20. The regulatory position of NRENs <ul><li>NRENs offer their services to the well bounded and closed community of education and research users. </li></ul><ul><li>NRENs are not in the business of providing public services and hence should not be regarded as public network operators. </li></ul><ul><li>It makes good sense for NRENs to adopt best industry practice in the operation of their networks despite being a non-public network operator. </li></ul>Slide
  21. 21. EU Regulatory Requirements for Data Collection and Retention Directive <ul><li>NRENs operate advanced networks with complex topologies </li></ul><ul><li>Any requirement to provide complete accounting for, or filtering of, traffic on the backbone would therefore be likely to require the re-introduction of single points of failure or congestion </li></ul><ul><li>Cost – who will pay? </li></ul>Slide
  22. 22. Possible Distortion of the Local Internet Market <ul><li>The NRENs operate a network for a closed user group that have advanced requirements </li></ul><ul><li>These requirements are not generally satisfied by commercial offerings from ISP. </li></ul><ul><li>The NRENs do not compete with commercial ISPs, but offer a different level of service in parallel. </li></ul><ul><li>It is beneficial for both NRENs and ISP to develop collaborative links and work together </li></ul>Slide
  23. 23. Summary of Arguments <ul><li>NRENs occupy a special position outside of the commercial Internet market. </li></ul><ul><li>They operate as not-for-profit organisations serving a closed user group consequently there is a case for them to be designated as non-public networks. </li></ul><ul><li>National governments should regard their NRENs as a national asset to be fostered and supported by central contributions to a hybrid funding model. </li></ul>Slide
  24. 24. The Case for NRENs <ul><li>idea conceived in 2007 </li></ul><ul><li>first version May 2008 </li></ul><ul><li>presented at TF-MSP/PR May </li></ul><ul><ul><li>Community feedback </li></ul></ul><ul><li>presented TF-MSP/PR Sept 08 </li></ul><ul><li>Second version October 2008 </li></ul><ul><li>presented at I2 fall meeting </li></ul><ul><ul><li>October 2008 </li></ul></ul><ul><ul><li>Community feedback </li></ul></ul><ul><li>Latest version 31 October 2008 </li></ul>Slide http://www.terena.org/activities/tf-msp/documents/the-case-for-nrens-current.pdf
