  3. Customized Approaches to Fibre-based E2E ServicesFirst attempts and trials • For E2E services – dark fibre is really needed. • First mile issues with fibres in many places. • Wireless can be used too but limitations may be rather significant (no WDM, 10G predicted, but higher speeds?, reliability and availability...). • First DF in CESNET in 1999, 2.5 Gb/s PoS. • Ethernet-based E2E services, shared capacity, VLANs (not E2E really). • More DFs have been acquired since then. • First international ‚lambda‘ link in the beginning 2003. • Connected to NetherLight, Amsterdam, the first international lambda exchange point of GLIF (now GOLEs ), 2.5 Gb/s SONET. • Ethernet-based E2E services, dedicated EoSONET channels. TERENA 1st E2E Workshop, Amsterdam

  4. Customized Approaches to Fibre-based E2E ServicesFirst attempts and trials • Both first (national and international) 2.5 Gb/s links were single channels, no CWDM or DWDM, • Evident limitation for E2E circuits/channels/lambdas when DFs are available. • ‚Grey‘ router interfaces with PoS only, no GE. • SONET/SDH repeaters only, no optical amplifiers. • Problem with international links because no DFs were available at that time (this situation has changed). • But the national infrastructure (MAN/WAN) started to utilize DFs more and more and CWDM/DWDM technology became available and economicaly feasible. TERENA 1st E2E Workshop, Amsterdam

  5. Customized Approaches to Fibre-based E2E ServicesProgress withFirst attempts and trials (GLIF) • GLIF links for new experiments with ‚lambdas‘ (ie E2E circuits). • The 2.5 Gb/s GLIF link to NetherLight upgraded to 10 Gb/s in September 2004. • Another direct 10 Gb/s GLIF link to StarLight, Chicago from December 2006. TERENA 1st E2E Workshop, Amsterdam

  6. 2002: first optical amplifiers (EDFA) • 2004: first CLA Customized Approaches to Fibre-based E2E ServicesProgress inCESNET networks • Evolution of the CESNET network 1999 – 2007 (not with all details). 2000 2001 2005 2005 2007 2007 TERENA 1st E2E Workshop, Amsterdam

  7. Customized Approaches to Fibre-based E2E ServicesUp-to-date situation in CESNET: WAN • CESNET2 network 2008 • 4700 km of DFs • Including 980 km single DF links TERENA 1st E2E Workshop, Amsterdam

  8. Customized Approaches to Fibre-based E2E ServicesUp-to-date situation in CESNET: WAN • 10 links Cisco 15454 MSTP n x 10 Gb/s DWDM transmission system (with ROADM). • 10 links (including 3 single fibre lines) deployed with open photonic n x 10 Gb/s DWDM transmission systems. • 5 other links will be lit in December 2008 (including 3 single fibre lines). • 2 international CBF connections to Bratislava and Wien: open photonic n x 10 Gb/s DWDM transmission system. • No bottleneck on international links anymore. • Customized Approaches in WANs. TERENA 1st E2E Workshop, Amsterdam

  9. Customized Approaches to Fibre-based E2E ServicesUp-to-date situation in CESNET: WAN • DFs with DWDM, CWDM not recommended. • Problems with amplification and number of channels. • But 10G CWDM transceivers available for interesting prices. • If distance is not an issue, use CWDM technology. • Equipment from different vendors in one network. • Open photonic DWDM systems are manufactured by photonic companies/vendors. • Not a ‚home made‘ black box without support and guarantee. • ROADMs and OOO switches have been developed and tested and can be deployed too, it is not restricted to ‚big vendors‘. • Booths both on OFC2008 and ECOC2008 – the global scope company. • Customized Approaches in WANs. TERENA 1st E2E Workshop, Amsterdam

  11. Customized Approaches to Fibre-based E2E ServicesUp-to-date situation in CESNET: MAN • Open photonic DWDM/CWDM transmission systems are used for end-user 1 Gb/s or 10 Gb/s wavelength connections, if needed. • Open DWDM/CWDM systems are used because of economic reasons, they are not that expensive but provide all required demands. • Particle physics research premises in Praha, along with a number of hospitals. • 10 Gb/s wavelength connection to the Barrandov Studios under construction. • Customized Approaches in MANs. TERENA 1st E2E Workshop, Amsterdam

  12. Customized Approaches to Fibre-based E2E ServicesUp-to-date situation in CESNET: MAN • With FTTx deployment, usage of metropolitan fibres lit by high speed open photonic DWDM is expected to be common. • Economic reasons. • ‚Openness‘ enables the solution of physical layer interoperability issues and decreases expenses as well as reducing equipment delivery time. • One example - equalizing power levels between two DWDM systems during GLIF 2007 demos. Demos07 TERENA 1st E2E Workshop, Amsterdam

  13. Customized Approaches to Fibre-based E2E ServicesApplications and E2E Connections I. • There are neither applications or E2E connections without physical layer (dark fibre) and photonic transmission technology. • Let‘s applications (end users/researchers) decide what technologies really fit their needs. • Meetings/workshops to share information. • We see demand for E2E services but rather permanent or semi-permanent, no on-demand. • Fibre in first miles is the most difficult issue. • With CWDM/DWDM it is easy to provide connectivity 24/7. • So reservation systems not have to be necessary. • Bottleneck are international (transatlantic) links.

  25. Customized Approaches to Fibre-based E2E ServicesConclusions I. • Open photonic systems offer freedom of design. • Device itself, following networks. • Important (but not limited) for first mile issues for E2E services. • Open photonic systems can offer beneficial cost advantages. • Ability to make savings on energy consumption, housing space usage, travel to remote huts. • The early adoption of the new photonic technology in the production network. • Independent knowledge of possible solutions. TERENA 1st E2E Workshop, Amsterdam

  26. Customized Approaches to Fibre-based E2E ServicesConclusions II. • The use of experimental dark fibre facilities (after laboratory testing) to verify feasibility of deployment in the production network. • The use of some services of the experimental facility for CESNET2 or end-user wavelength connections (support of long term experiments with real usage). • Presented examples of E2E services are usable globally. • When DFs are available, of course. • Rather permanet or semi-permanent E2E fibre services then SW reservation systems. • This is our experience with researchers – no additional SW. • But our CLM and CLSs devices include remote management and a SW time scheduler. TERENA 1st E2E Workshop, Amsterdam

  27. Customized Approaches to Fibre-based E2E ServicesConclusions III. • CESNET is ready to support pilot deployments of E2E fibre services. • Designs and concepts. • Theory or paper works. • CESNET can provide details of already deployed projects. • Practical aspects and hands-on experience. • The vendor is a global company. • Not black boxes manufactured in a garage. • Support, guarantee.
