Job description

The Informatics Institute (IvI) is one of the eight research institutes of the Faculty of Science with a focus on complex information systems divided in two broad themes: Computational Systems and Intelligent Systems. The institute has a prominent international standing and is active in a dynamic scientific area, with a strong innovative character and an extensive portfolio of externally funded projects.

The IvI covers a wide range of subjects, in both fundamental and applied research. The System and Network Engineering (SNE)  group researches cross-domain interaction between Grid resource providers, optical and hybrid networking, resource descriptions using semantic web and programmable networks for the Future Internet. In collaboration with SURFnet and SURFsara, UvA has capabilities to access high-speed optical test bed installations in the optical photonic backbone of SURFnet in the Netherlands and internationally in the Global Lambda Integrated Facility (GLIF).

Project description

The SNE group has an opening for a postdoc position in the area of networking research. The work is to be initially carried out within the GN3plus project, which will start in October 2013 and will end in April 2015, and later within the national project COMMIT.

The research focus will be on the development of multi-domain topology descriptions supporting network provisioning for Software Defined Networking (SDN) technologies. In particular, we intend to bridge the intra-domain operations of OpenFlow with the inter-domain provisioning in the Network Service Interface (NSI) Framework.

OpenFlow is a Software Defined Networking technology, which is seen as a serious candidate to allow the extension of network circuits into the campus networks. NSI is a framework developed in the Open Grid Forum whose standardized interfaces allows communication between different networks bandwidth-on-demand or circuit reservation systems. The integration of OpenFlow with NSI will be a step forward in the definition of services for the Future Internet.


The postdoctoral researcher will perform a preliminary study to closely examine the workings of OpenFlow, especially regarding network topology descriptions. He/she will identify the required extensions needed to the NSI Framework. The postdoc will build an OpenFlow testbed to be interconnected with many other testbeds, including SURFnet, ExoGENI, GÉANT and the UvA’s existing OpenFlow testbed. Here he/she will create proof-of-concept implementations of the ideas produced in the study. The task will coordinate his/her activities with SURFSARA, also partner in this project, and he/she will needs to travel and present his work within the activities organized by the GN3plus consortium.


  • PhD in computer science, with focus on network and systems engineering;
  • experience with network modelling techniques and semantic web languages;
  • knowledge of circuit switching architectures;
  • fluent in English;
  • ability to work in an international research team.

Conditions of employment

The position will start in fall 2013. The appointment will be full time (38 hours a week) on a temporary basis for a maximum period of two years. The gross monthly salary will be in accordance with the University regulations for academic personnel, and will range from €2,427 to a maximum of €4,462 (scale 10/11) based on a full-time appointment depending on qualifications, expertise and on the number of years of professional experience. The collective employment agreement of Dutch universities is applicable. There are also secondary benefits, such as 8% holiday allowance per year and the end of year allowance of 8.3 %.
