Netherlands: PhD in Network Infrastructures at Delft University of Technology

Font size: Decrease font Enlarge font

Job description:

Network infrastructures are becoming increasingly difficult to manage due to: a) the complexity in configuring many devices and mechanisms, b) an increase in (large data) applications that demand Quality of Service (QoS) and careful traffic engineering to avoid network congestion, and c) equipment inter-vendor inoperability. In Software Defined Networking (SDN), the aim is to solve these issues by decoupling the control plane from the forwarding plane and introducing a centralised controller that monitors the network and configures the router forwarding planes by assigning paths to data flows. Since a centralised controller is used, it could – through proper network monitoring – obtain a good view of the network and its QoS parameters, which opens the door to new ways for dynamically calculating paths and offering tailor-made service, but also allowing quicker reactions to security risks and network failures. However, the centralised nature of the SDN architecture raises scalability concerns. This PhD project will focus on a) design rules for an efficient, survivable, and scalable SDN network, b) the development of QoS algorithms for an SDN network, c) experiments with the developed tools on an SDN testbed, and d) inter-domain SDN operability.


The successful candidate has obtained a master’s degree in electrical engineering or computer science and has an affinity for internetworking from a practical (e.g., experience with routers) as well as a theoretical (e.g., network and algorithm design) perspective. The candidate is a team player, cooperating with other PhDs on related research topics in the NAS group as well as with network operators from industry. Due to the collaboration with industry, the ability to speak Dutch is an advantage.

Conditions of employment:

TU Delft offers an attractive benefits package, including a flexible work week, free high-speed Internet access from home (with a contract of two years or longer), and the option of assembling a customised compensation and benefits package (the ‘IKA’). Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.

Delft University of Technology

Delft University of Technology (TU Delft) is a multifaceted institution offering education and carrying out research in the technical sciences at an internationally recognised level. Education, research and design are strongly oriented towards applicability. TU Delft develops technologies for future generations, focusing on sustainability, safety and economic vitality. At TU Delft you will work in an environment where technical sciences and society converge. TU Delft comprises eight faculties, unique laboratories, research institutes and schools.


Electrical Engineering, Mathematics & Computer Science

The PhD opening is in the Network Architectures and Services (NAS) section in the Faculty of Electrical Engineering, Mathematics, and Computer Science (EEMCS) at Delft University of Technology.
The Network Architectures and Services (NAS, section of the Intelligent Systems Department educates and conducts research in the broad area of complex networks, ranging from data communications and Internetworking, to other man-made infrastructures such as energy networks, and to biological and social networks.
NAS has expertise in concepts (e.g., Quality of Service routing, robustness) of (future) network architectures, in the performance analysis of quality of service-aware protocols and Internet behaviour, and in strategic and business-oriented challenges for network operators.
