9th CEF Networks Workshop 2017

Quick navigation:

We held the 9th Customer Empowered Fibre Networks Workshop in Prague from September 11th to 12th. Major topics for this year event were:

  • Multi-vendor/disaggregated lighting of CEF networks, interoperability and vendor-independent description of transmission systems
  • Support of new applications and disciplines requiring photonic or dark fibre connectivity (cryptography, metrology, seismology, space, observation, sensor networks, etc.)
  • End to end services for high precision and high performance applications, real-time applications of wide-area all-optical networks
  • Photonic (all-optical) services, dark fibre channels, alien waves, fibre sharing, optimal or dynamic usage of transmission spectrum and virtual fibre networks
  • SDN Approach for Systematic Service Design Methods including Lower Layers of the Networking Stack
  • Dark fibre or channel testbeds used for experiments and additional production traffic
  • Deployments and testing of high-speed transmission systems, power consumption of transmission systems(greening)
  • Update of dark fibre footprint used for Research and Education
  • Community (campuses, regional, national or continental) and experimental facilities (testbeds)
  • Development of dark fibre footprint used for Research and Education
  • Community (REC) in Asia, Australia, North America, South America and Europe
  • Improvement of long term REC economy

How to get there

The location of Computing and Information Centre is really suitable. There is a good connection from/to the airport in less than 30 minutes. When using public transportation, bus 119 plus metro, or tram is available. CESNET premises are very near the venue.  See the map and instructions on Google Maps.

From the airport:
Bus no. 119 (stop is in the middle of the car park outside the arrival hall, just walk straight and look for the signs) will take you to the Metro station “Nadrazi Veleslavin” (15 minutes). Bus 119 ends here, so don’t worry. Change to Metro (subway) and go two stations in direction “Depo Hostivar” to the station “Dejvicka”. The bus comes quite frequently—see the time table. You have to buy a general public transport ticket and stamp it inside the bus. The tickets are sold at yellow vending machines  in all metro stations or tram stops and newspaper kiosks for 32 CZK (about 1.2 Euro).
From anywhere else:
Use subway (Metro). Go to the line A and then to the Dejvicka station. Plans of Metro lines are available on stations and inside trains (above every door).

Accommodation tips

We can recommend following accommodation options for the participants of the workshop. All hotels are located nearby the workshop venue.
