Customized Approaches to Fibre-based E2E Services First 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 2 Dec, 2008 3
Customized Approaches to Fibre-based E2E Services First 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 2 Dec, 2008 4
Customized Approaches to Fibre-based E2E Services Progress with First 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.

Customized Approaches to Fibre-based E2E Services Up-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 2 Dec, 2008 8
Customized Approaches to Fibre-based E2E Services Up-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 to Fibre-based E2E Services Up-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.

Customized Approaches to Fibre-based E2E Services Up-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 2 Dec, 2008 12
Customized Approaches to Fibre-based E2E Services Applications 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. CESNET2 TERENA 1st E2E Workshop, Amsterdam 2 Dec, 2008 13
