At Simula Research Laboratory (Norway) there is an available PhD position in the area of in Time-Dependent Networking. The PhD Student will work in the area of networking support for time-dependent applications, focusing on thin streams. Thin streams are generated by applications that send data with high interarrival time and also often small packet sizes. These traffic patterns are in stark contrast to greedy streams where the application always has data to send and the sending rate is limited by congestion control. Typical for thin streams is that they are generated by interactive applications with a need for low latency communication.

The following topics are central for the work in this position:

• Develop mechanisms to improve thin-stream latency when transmitted via different buffer types with varying drop schemes.
• Investigate the congestion control support of conditionally thin streams (i.e. not everything must be sent at all times) via per-packet priorities.
• Work towards a formal definition of the concept of thin streams.
• Work towards defining what TCP fairness must mean in thin-stream scenarios.

The position is connected to the "Traffic behaviour of interactive time-dependent thin streams on the modern Internet" (TimeIn) research project cooperating with partners like UNINETT, University of Oslo, Karlstad University, University of Kaiserslautern, CAIDA San Diego, Cisco and Funcom.

It is planned to align the research with, and possibly contribute to, ongoing standardization efforts in the RTP Media Congestion Avoidance Techniques (RMCAT) working group in the IETF.
