  1. Network InfrastructuresA view from the campus Jean-Paul Le Guigner Jplg@cru.fr

  2. Before the last slide (in case I forget;-) No homogeneous view • From the best to the badly off. Real contrasts depending on where « you » are : • Geographical location • University policy / strategy concerning IT For many (campus) still a long way to go Not for the larger ones

  3. French networking infrastructure three (even four) storeyed rocket • Problems deriving from that situation : • disparity between national and regional ambition • different timings • regional-networks.version-X and Renater.version-X+1 • different communities served • requirements not coherent

  4. Internet Res. & Educ. Internet Renater3 From 1 to 2,5Gbs 2,5Gbs Regional networks MAN ISP (ISDN, ADSL, LRL) MAN GE

  5. Who’s in control Internet Internet GIP Renater Our community Renater Collectivités régionales autres coll. territoriales Regional Networks MANs Universities and research institutions

  6. Who’s is paying Internet Internet Our community Through national representation GIP Renater Renater Collectivités régionales autres coll. territoriales Regional Networks MANs Universities and research institutions

  7. Level by level

  8. 2.4 Gbit/s 155 Mbit/s 34 Mbit/s RENATER-3 Lille Rouen Compiègne Strasbourg Caen Reims Paris Nancy Rennes Dijon Nantes Orléans Poitiers Besançon 622 Mbit/s Clermont- Ferrand Lyon Limoges Bordeaux Grenoble Montpellier Sophia Toulouse . Marseille Corte

  9. INTERNATIONAL CONNECTIONS GEANT Paris AmericaInternet 2AsiaPacific Internet :SFINX (french GIX) Lyon Koréa: TEIN DOM - TOM

  10. Campus networks • Key points : • Network backbones at Gbits/s with : • reliability (organisational and infrastructure issues) • security (VPNs), • implementation of CoS. [VoIP, Videoconf, …] • 10 Mbits/s really available to the end users (100 if needed) • less than 10 as a factor of overallocation Still objectives on several campuses

  11. MANs Mastered by our community • Ownership of infrastructure • Or leasing of services (where several competitive offers exist) In operation:Strasbourg, Besançon, Montpellier, Nancy, Metz, valenciennes, Limoges, Rouen, Lyon, Caen, Grenoble, 4 en Ile de France, Toulouse, Rennes, Brest, Le Havre, Nantes, St Etienne, Dijon, … Projects: Bordeaux, Amiens, 2 en Ile de France, Reims,

  12. Regional networks • First versions in early 90’s now in « version 2 » for most • Not running as fast as Renater • Reasons ? (be careful, no true in every case) : • « regional governments » not convinced but the specific needs of the research and higher education community, • No competition  no real alternative level of costs • No involvement of our community in the final engineering of the network (the operator provide a multiservice stuff), ending up as a « blackbox », not even magic  And neveretheless they are essential in our model. To day they are the weakest links.

  13. Status for universities Listed by catégories • Those with one (main one) campus connected HSpeed Plus: the one called « quickly connectable » under some conditions (not really a problem). • Those « connectable after some efforts  »  • Approach of regional management • Those not connectable in a short term 48 13 19 But, all universities have multiple campus spread Around. So even if one (closest to the Renater NRD) is correctly connected, several others may not be

  14. Needs and requirements • Cultural exception? NO  same as in other countries • A short list: • Facilities sharing (storage, [meta-]computing, …), • Performant institution or project VPNs, • QoS(Something) for : • Videoconferencing and VoIP, • Collaborative working, (peer to peer  buzzword?) • Distance teaching • Mobility (but this is more or like a local issue)
