The Annexus building is the basement of A1, but the access is from the Gran Capità street, not from the ground level at A1). Take the metro or the tram, stop at Zona Universitària and it's less than a 10 min walk. The path is totally accessible, including the metro station (there are elevators to the platforms and the street) and the A1 building (street level).

Accommodation

CSUC is not in the city centre, but in Zona Universitària, where many faculties and schools are. Below you can find affordable hotels and residences in the vicinity of CSUC offices. There are also many other hotels in the city. So, if you prefer to stay in the city centre, you can still reach the office with public transportation quite easily. You can use the CSUCAH discount code with Atiram Hotels (8% discount).

This is a list of possible hotels and residences for your stay, sorted by the time you will spend to reach CSUC:

Getting to Barcelona from the airport Barcelona El Prat Josep Tarradellas

We recommend you fly to Barcelona El Prat Josep Tarradellas airport (BCN). Some applications show the airports of Reus and Girona as if they were Barcelona. They are not. They are far away and you can only reach Barcelona by bus from there. So, please, fly to BCN. There are two terminals: T1 and T2. If you need to take a bus, train or metro in the other terminal, there is a free shuttle bus between the two terminals every 5 minutes. Then, from the airport to the city, you can choose:

  • Aerobus is a direct bus from the airport (T1/T2) to the city centre (aerobus). It cost 7,45 € per trip (12.85 € if you buy the return ticket).
  • You can take bus number 46 from the airport (T1/T2) to Plaça Espanya. It costs 2,65 € per trip and you can buy a single ticket inside the bus (or 1,25 € if you buy a T-casual first). Please, be aware you can not buy a T-casual inside the bus, but you can buy at the metro station and then go to the bus if you want. Also, take into account you can pay in TMB buses directly with your bank card and no physical ticket will be needed in this case.
  • Metro line 9 stops directly in Zona Universitària (where CSUC is). You need to pay a special fee to travel from the airport (Airport ticket). It costs 5,70 €.
  • There is a train from the airport to Sants Estació and Passeig de Gràcia (only from T2). It costs 5.05 €.
  • More information about public transportation from/to the airport here: https://www.ambmobilitat.cat/Principales/Aeropuerto.aspx
  • You can take a taxi (there are well-signalled taxi stations there). Expect around 34/40 € from the airport to the city centre.
  • Uber, Cabify, Mytaxi and other apps work quite well in Barcelona.

The most efficient way to travel with public transportation in Barcelona is to buy a T-Casual card in any metro machine for 12.55 € (+0,50 € carton rechargeable card), which includes 10 trips with the right to exchange between buses (except Aerobus), metro (except from/to the airport), train Zone 1 and tram during 75 minutes. If you are going to use more than 6 single tickets, is worth buying a T-casual.  You can find all the possible tickets here: https://www.tmb.cat/en/barcelona-fares-metro-bus/. You will read you can only use the T-casual with the T-mobilitat and that you need to register, but the truth is that you can buy a carton rechargeable card per 0,50 €. You can also buy an "Hola Barcelona" card for 2 to 5 days, that includes Aureobus.

For single tickets (2,65 €): You can pay in TMB buses (reb buses, most of them) directly with your bank card and no physical ticket will be needed in this case. When you get on the bus through the first door, you will find a reader in front of the cab. It is the contactless bank card reader that allows you to buy and validate the single bus ticket in a single step, just by approaching the card. In some metro accesses, there is also a special validation machine that allows you to buy and validate a single ticket with a bank card. If this is not the case, you can use the machines to buy your ticket.

Practicalities

  • The currency is the Euro (€).
  • You can pay with credit card almost everywhere, including taxis.
  • Power plugs are Type F ( CEE 7/4 and CEE 7/7 standards).  The standard voltage is 230 V at a frequency of 50 Hz.
  • Passport needed for countries out of Schengen area.
  • We do not recommend to fly to Reus or Girona, as these two airports are far away from Barcelona.
  • There is roaming available from most EC countries.

Maat, Tomasz Szewczyk, PCSS

Maat is a Source of Truth application that ensures efficient management of infrastructure information in network service orchestration and automation systems. The approach used allows for easy definition of advanced resources and services and the creation of relationships between them. The application offers secure REST API, a nice UI, authentication and authorization features using the well-known open-source Identity and Access Management software Keycloak.

Developed under the GN5-2 project and released under the open Apache v2 license, Maat has already proven its value in production within the Polish PIONIER network, where its adaptability and ease of modelling resources and services have earned the trust of network engineers.

Improving identification of R&E network traffic - Tim Chown, Jisc

The scientific network tags (Scitags) project is developing software tools to allow better identification of the owner (community) and purpose (activity) of science traffic by NRENs, other network operators and research communities. Scitags supports marking on a per-packet basis using the IPv6 flow label or per flow using parallel UDP “firefly” packets. The approach is already in use in CERN’s Worldwide Large Hadron Collider Computing Grid (WLCG) infrastructure, but is extensible to other projects and (non-science) communities.

  • GREN Map, Gustavo Araujo, RNP
    The idea of sharing research and education networks data in order to create a global map and see their network topology has been around for years. What prerequisites, pros and cons are there around the idea.
  • perfSONAR on-demand measurements UI, Ljubomir Hrboka, CARNET
    perfSONAR is the performance Service-Oriented Network monitoring ARchitecture, a network measurement toolkit designed to provide federated coverage of paths and help to establish end-to-end usage expectations. Recently renewed UI for on-demand measurements will be presented and demoed.
16:15 - 17:00

Discussion: How many data would you like to see and share?, Ivana Golub, PCSS

Research and education institutions participate in many multidomain project that require a resilient end-to-end network. But, what happens when there is a problem and we can not see the whole path? Are we willing to share our data? And, if so, up to how many data would we share? Following the example from Metranova, we will see the possibilities we have, examples, etc.

  • Mobile App Network trAffic Nutrition fActs (MANANA)  - Giuseppe Aceto, UNINA

    End-users of mobile applications hardly know which enterprises and countries are involved in their online activities, and the implied rights and risks. Researchers and regulators need actual usage data to verify data sovereignty compliance. MANANA aims at providing the former with understandable characterisations of infrastructure usage, and the latter with a monitoring system of actual mobile apps usage. The user will be enabled to choose among similar apps and report her data exposure (providing visibility to authorities). The app and the collection server will be released as open-source. MANANA is a project from the Università degli Studi di Napoli Federico II, funded by GÉANT's Innovation Programme.
