About the position

The Department of Information Security and Communication Technology (IIK) has a vacancy for a position as a PhD Candidate at the Faculty of Information Technology and Electrical Engineering (IE), in the area of networking with focus on Service Differentiation in Future Networks.

This is a researcher training position aimed at providing promising researcher recruits the opportunity of academic development in the form of a doctoral degree.

The position's working place is at NTNUs campus in Trondheim and reports to the Head of Department.

Main duties and responsibilities

The appointment is for a term of three years, or 4 years including 25% duty work. Future networks will, on the same physical infrastructure, provide a wide range of services differing extremely in terms of capacity, real-time properties, dependability and security. The foreseen means to deal with this are virtualization both for sharing resources (link capacities, processing), virtual network functions (VNFs), and highly advanced management and orchestration. This poses a number of fundamental, yet unresolved technological challenges.

Depending on the skills of the candidate, different aspects may be emphasized, for instance by focusing on

  • Modelling and analysis of service differentiation in context of dynamic resource sharing, e.g. as in 5G network slicing.
  • Allocation of virtual functions (NFV) and resources (link capacities, processing) to actual physical resources in a multi-service, multi-user, multi-operator setting governed by Service Level Agreements (SLAs).
  • Realization and experimental evaluation of service isolation (with regard to performance, dependability and security) while statistically sharing the same physical resources.
  • Focus on cost of Service differentiation (cost of basic versus extra quality services; willingness of users to pay for extra quality; cost related to service isolation mechanisms, etc.)

The research will be carried out as an integrated part of the Networking Research group, and under guidance of Professor Norvald Stol.

Qualification requirements

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master’s degree or second degree (equivalent to 120 credits) with a strong academic education covering the following areas:
