Connect. Communicate. Collaborate Seite 2 Contents –Technical Challenges –Some Definitions –Forecasts (Communication market) –Example (NRENs) –Conclusion 1 (bandwidth perspective) –Forecasts (VPNs/OPNs, Role of Grids for networking) –Example (LHC optical private network) –Conclusion 2 (cooperation with users) –Forecast (transmission technology, qualitative user demands) –Conclusions (network technology developments) –Organisational Challenges –NRENPC as governing structure –Conclusion on governing structure –Summary

Connect. Communicate. Collaborate Seite 3 Technical Challenges

Connect. Communicate. Collaborate Seite 4 Some Definitions VPN: Virtual Private Network - a „user-owned network“ which is built from a basic technical platform (IP / SDH / DWDM...) OPN: Optical (Virtual) Private Network - a VPN based on optical technology Hybrid Network: Router based network using a VPN / OPN as a platform

Connect. Communicate. Collaborate Seite 5 Forecast (Communication Market) (1) liberalisation of the communication market in all European countries will continue and will decrease the „digital divide“ (or the economic conditions for that divide)

Connect. Communicate. Collaborate Example 1: X-WiN (typical NREN as of 06/06) FFO KIE HUB ADH EWE GIE GAR ERL BAY MUE FZJ AAC BIR HAM DES POT TUB FZK GSI DUI BRE HAN BRA MAG BIE FRA HEI STU REG DRE CHE ZIB ILM ROS LEI JEN ESF AWI GOE KAS MAR GRE WUE AUG SAA KEH CBF DFN PoP Dark fibre Wavelength Surfnet PSNC Switch/GARR Renater Geant2

Connect. Communicate. Collaborate Seite 7 Example 1: X-WiN as a hybrid network Platform for a couple of national VPNs/OPNs and for the national part of intl. VPNs/OPNs Was possible due to lively fibre market in Germany Optical technology delivers ample bandwidth, i.e. 160*10G per link Costs per 10G link are relatively low (as in Geant2) - in the order of 30K€/a for 10G

Connect. Communicate. Collaborate Seite 8 Conclusion 1 Bandwidth, which has been the major problem for any research networking over the past decade will not be a major problem in the future

Connect. Communicate. Collaborate Seite 9 Forecasts (VPNs/OPNs) (2) VPNs/OPNs will in a few years carry the bulk of scientific data in European networks (NRENs/Geant) and also worldwide (3) Migration to that scenario is an evolutionary (rather than a revolutionary) process defined by user group´s needs and available network technology

Connect. Communicate. Collaborate Seite 10 Forecasts (Role of Grids) (4) Grids will be a major driver for the VPN migration scenario process (example LCG- OPN... see special overhead) (5) Grid infrastructures have commonalities with network infrastructures but are different as well

Connect. Communicate. Collaborate Seite 11 (6) Networking technology developments like network management (example: monitoring of VPNs/OPNs) or network security are still needed for serving „Grid infrastructures“ Forecasts (Role of Grids contd.)

Connect. Communicate. Collaborate Seite 12 Example 2: LCG OPN in Europe T1-T0 primary connection for „GN2 fibre cloud NRENs“ through Geant2; T1-T1 secondary connection on separate fibre paths through other fibre. Secondary connections provide resilience OPN approach; high data volume expected, Grid middleware driving this appraoch; „low“ prices (due to liberalized situation per country) makes it possible

Connect. Communicate. Collaborate Seite 15 Conclusion 2 Developments for future network technology have to be done in close cooperation with advanced user groups, specifically those using Grid technology

Connect. Communicate. Collaborate Seite 16 Forecasts (transmission technology) (6) On a per (user-) stream basis 10G will be the top-bandwidth to be used over the next 2-3 years perhaps even longer - the difficulty is to get data from / to sources / sinks at higher speeds than 10G (7) 40G or 100G per (user-) stream will follow. (8) 10G equipment will be very „cheap“

Connect. Communicate. Collaborate Seite 17 Forecasts (qualitative user demands) (9) The user (group) demand in the research area is in almost all cases „multi-domain / multi vendor“ in networking terms (--> see LCG example) (10) Users will require „intelligent networks“, i.e. network technology which adapts (at best dynamically) to their requirements

Connect. Communicate. Collaborate Seite 18 Conclusions 3, 4: One of the main future challenges for the developments of research networking is to further work out solutions for multi-domain environments for operational purposes Work started in GN2 („e2e“) but solutions have to be driven further according to developing demands for example from Grid communities

Connect. Communicate. Collaborate Seite 19 Conclusion 5: Intelligent networks (i.e. „intelligent“ VPNs / OPNs adaptable more flexibly to user needs) have to be further developed in the future, i.e. VPNs „on demand“ or dynamic VPNs

Connect. Communicate. Collaborate Seite 20 Organisational Challenges

Connect. Communicate. Collaborate Seite 21 Governing Structure Presently the NREN Policy Committee (NRENPC) is successfully governing the networking policy definition and always devised a flexible substructure (for example Exec) to adapt to management needs - the forecast is that this will be the case in the future as well

Connect. Communicate. Collaborate Seite 22 The NRENPC as of 09/06 Austria (ACOnet) Belgium (BELNET) Bulgaria (ISTF) Croatia (CARNet) Czech Republic (CESNET) Cyprus (CYNET) Germany (DFN) Estonia (EENet) France (RENATER) Greece (GRNET) Hungary (HUNGARNET) Ireland (HEANet) Israel (IUCC) Italy (GARR) Latvia (LATNET) Lithuania (LITNET) Luxembourg (RESTENA) Malta (UoM) Netherlands (SURFNET) Nordic Countries – Denmark, Finland, Iceland, Norway, Sweden (NORDUNET ) Poland (PSNC) Portugal (FCCN) Romania (RoEduNet) Russia (JSCC) Slovakia (SANET) Slovenia (ARNES) Spain (RedIRIS) Switzerland (SWITCH) Turkey (ULAKBIM) United Kingdom (UKERNA) PLUS NON-VOTING MEMBERS: DANTE, TERENA PERMANENT OBSERVERS: CERN, AMREJ, MARNET

Connect. Communicate. Collaborate Seite 23 Conclusion 6: NRENPC At this point in time there is no need to change that structure as it is working and flexible enough for its purpose.

Connect. Communicate. Collaborate Seite 24 Governing Structure for Grids This is the real organsational challenge for the time to come to find an appropriate governing (?) / coordination structure for Grid computing in Europe Some similarities with NRENs (i.e. coordina- tion), some non-comparable issues for example: missing central capability like Geant NRENs can bring in their experience for that process if needed.

Connect. Communicate. Collaborate Seite 25 Summary (1) Bandwidth, which has been the major problem for any research networking in Europe over the past decade will be no longer a major problem Developments for future network technology have to be done in close cooperation with advanced user groups, specifically those using Grid technology

Connect. Communicate. Collaborate Seite 26 Summary (2) Due to the user demands one of the main future challenges for the developments of research networking is to further work out solutions for multi-domain environments for operational purposes. Work started in GN2 („e2e“) but solutions have to be driven further according to developing demands for example from Grid communities

Connect. Communicate. Collaborate Seite 27 Summary (3) Intelligent networks (i.e. „intelligent“ VPNs / OPNs adaptable more flexibly to user needs) have to be further developed in the future, i.e. VPNs „on demand“ or dynamic VPNs Presently there is no need to change the governing structure as it is working and flexible enough for its purpose.
