May 14, 2019

In this spotlight, we would like to introduce two contributors from the ONF ODTN community – Ramon Casellas and Alessio Giorgetti. Ramon is a senior researcher at CTTC in Barcelona, Spain. Alessio is an assistant professor at Scuola Superiore Sant’Anna in Pisa, Italy and an affiliate researcher of the CNIT consortium in Pisa, Italy.

Both have been collaborating as members of the European Commission Metro-Haul project. Thanks to their involvement with the Metro-Haul project, they have made several contributions to the ODTN project while participating in its use case and software development groups including:

  • Contribution to the ONOS ODTN project application, in collaboration with NTT (Hiroki Okui and Ai Hamano) et al.
  • OpenConfig Optical Terminal Device drivers for client and line side configuration through flow rules and optical intents
  • OpenROADM v2.2 Drivers
  • Demos and outreach of their work on ONOS, e.g. at different ECOC and OFC conferences

Ramon has also focused on:

  • Contributions to the TAPI v2.1 North Bound Interface (NBI) for the Photonic Media Layer, including processing of connectivity requests and mapping them to Optical Connectivity Intents, in collaboration with NTT
  • Being a liaison between the ODTN project (in which he is participating upon invitation by Telefónica) and Metro-Haul, where  he is leading the work package on Network Control and Management for the Software-enabled metro network.

Ramon has twins less than a year old (high availability) and in his shrinking free time he likes to do programming, swimming and biking.
