Experience with CBF connection in Europe Research cooperation instead of fibre leasing can be Experience with CBF connection in Europe Research cooperation instead of fibre leasing can be successful start l l In some European countries, providing of telecommunication services (and especially fibre leasing) are still limited by legal or regulatory rules, but research is not restricted. First dark fibre line used in CESNET (Praha-Brno 324 km) since 1999 is part of contract with fibre owner company. Subject of contract is research cooperation (evaluation of some new usage possibilities, etc. ). It is acceptable for Regulator (everybody cannot ask similar „exception“). It was better than wait for telco market liberalization Porta Optica Study Regional workshop, Kiev, October 11 th, 2006 3

Experience with CBF connection in Europe Why dark fibre for Research and Education Networks Experience with CBF connection in Europe Why dark fibre for Research and Education Networks (RENs)? (we have published this slide in TNC 2004, Rhodes) l l l l Freedom in REN design Fixed costs of long-term use Transmission capacity up to Tbps Cost-effective ways of sharing (WDM, TDM, …) Multiple wavelengths possible (e. g. 1 – 256) Management of transmission Equipment selection, moving, design, …. .

Experience with CBF connection in Europe Dark Fibres are crossing Borders l l l Experience with CBF connection in Europe Dark Fibres are crossing Borders l l l Dark fibres connecting capitals or main Po. Ps, as in GEANT 2 core or in National Lambda Rail (NLR) in US are crossing state borders, of course. By Cross Border Fibre (CBF) we mean other fibres, connecting NREN Po. Ps close to neighbour NREN. CBFs are usually short and non-expensive and carry high traffic between neighbour NRENs, saving expensive long distance fibres capacity Porta Optica Study Regional workshop, Kiev, October 11 th, 2006 8

Experience with CBF connection in Europe CBF to CBF traffic transit l l CBFs Experience with CBF connection in Europe CBF to CBF traffic transit l l CBFs can be used not only for neighbours connection, but also for traffic transit through NREN. Transiting NRENs are (in historical order) SANET, CESNET and SWITCH – as pilots for evaluation of possibilities. In principle, transit service (Eo. MPLS, lambda, etc. ) implemented by NREN can be less expensive than any other party service, but not free of charge. CBF to CBF transit is rather economical than technical issue.

Experience with CBF connection in Europe Cross Border Dark Fibre Triangle l l Multiple Experience with CBF connection in Europe Cross Border Dark Fibre Triangle l l Multiple 10 gigabit connection of Austrian, Czech and Slovak research and education networks In the case of fibre failure, triangle connection allows redirection of traffic in less than 60 ms, so overall reliability of end to end connections is improved significantly. This is achieved by Level 2 protocols (802. 1 q and 802. 1 w), avoiding slower and more complicated solution on IP level. 10 GE VLANs are implemented on this background, giving impression of distances between countries disappeared.

Experience with CBF connection in Europe NIL 8 x 10 Gb/s over 224 km Experience with CBF connection in Europe NIL 8 x 10 Gb/s over 224 km l l l All devices have been installed only at the end points of the line in Brno (CZ) and Wien (AT) and no in-line elements have been deployed. Nothing In Line (NIL) approach has been used and according to our knowledge, 8 times 10 Gb/s over 224 km of dark fibre is the longest NIL distance that has been reported for any production network. The main advantage of NIL solution is represented by lower capital and operational costs and increased reliability. Porta Optica Study Regional workshop, Kiev, October 11 th, 2006 16

Experience with CBF connection in Europe Enabled by advanced photonic technology l l l Experience with CBF connection in Europe Enabled by advanced photonic technology l l l The fibre pair from Brno to Wien has been equipped with CLA PB 02 optical amplifiers, developed as a part of optical research activities of CESNET. Chromatic dispersion of G. 652 optical fibre has been compensated by new compensating elements – Fiber Bragg Gratings (FBG). FBGs were successfully deployed and tested for the first time on the CESNET 2 line Brno – Bratislava in February 2006. Terminal routers are equipped with Xenpak DWDM pluggable optical transceivers. First one company has received CESNET licence for CLA manufacturing, the second should follow shortly. Porta Optica Study Regional workshop, Kiev, October 11 th, 2006 17

Experience with CBF connection in Europe Fear of new results? l l Legacy approach: Experience with CBF connection in Europe Fear of new results? l l Legacy approach: to buy transmission equipment from big vendors (remaining barrier in networkers mind) New approach tested by CESNET since 2002: take advantages of both legacy approach and new photonic products, i. e. use mixed vendor network design Similar approach of SWITCH see in CEF 2006 Resulting recommendation: do not afraid of – new products of photonic industry and – networking research results Porta Optica Study Regional workshop, Kiev, October 11 th, 2006 18
