Current 5G and future 6G cellular technologies rely on virtualization technologies, and virtualized Radio Access Networks (vRANs) are one of their major keystones. In order to make vRANs widely adopted and deployed by the telecommunication players, a new Open Radio Access Network (O-RAN) architecture has been proposed to allow for open, standardized interfaces and multi-vendor, interoperable components in the Radio Access Networks to enable truly flexible and virtualized deployments following the cloud-native principles. However virtualizing the RAN comes with challenges. In order to effectively achieve such virtualization levels, O-RAN must ensure that the network can be shared while keeping deterministic performance requirements, especially those interfaces that are time-critical. In this sense, Time Senstive Networking (TSN) stays as a promising approach to provide Ethernet-based vRANs fronthaul and midhaul networks with the ability of being shared by different traffic types, while ensuring deterministic performance for the time-critical flows.
The goal of this thesis will be to investigate, apply and verify different TSN-enabled approaches to guarantee that vRAN high-priority flows comply with their time-critical requirements on different O-RAN scenarios and use cases.
Who we are:
The i2CAT Foundation is a non-profit research and innovation center that promotes mission-driven R&D activities on advanced Internet architectures, applications, and services. More than 15 years of international research define our expertise in the fields of 5G, IoT, VR, and Immersive Technologies, Cybersecurity, Blockchain, AI, and Digital Social Innovation. The center partners with companies, public administration, academia, and end-users to leverage this knowledge in order to meet real social and business challenges.
The greatest value of i2CAT is the talent of the people who make up our human team. We enjoy a team of people from more than 13 different nationalities and work every day to create and foster a work environment where we all feel comfortable creating, innovating and growing.

What do we offer?
Where will you do it?
At i2CAT we already have an established telework policy for some time. You can work from home or from the office, whichever suits you best. We ask that you attend the office two days per week, one to stay connected with the team and the other one to establish relations.
If you decide to come to the office, we are located in Zona Universitària, next to the Campus Nord of the UPC, within a multidisciplinary and multicultural environment. It is a very well connected area (metro, tram, bus) with bars and restaurants around.
Our offices are designed with an open-office concept where everything is light and transparency (we do not have opaque rooms). We have a variety of workspaces so that you don't have to be at the same table all day.
i2CAT is an organization committed to equal opportunities. That is why we seek to increase the number of women in those areas where they are underrepresented, and therefore explicitly encourage the female collective to apply.
i2CAT is an organization committed to diversity and we seek to increase the number of people with disabilities in our team.
