After a long period of silence, currently a renewed interest in congestion controls is seen. The possibility to quickly deploy and adapt new congestion control algorithms allowed many application service providers (Google, Netflix, Microsoft, …) to try new angles which resulted in many novel congestion control schemes for TCP and QUIC (BBR, DCTCP, TCP-Prague, IoT CCs, …). Their new challenge is to provide low latency and high utilization and later to support the highly varying throughput which is to be expected in the 5G network context. As a network equipment provider, we are looking into ways to improve the interaction between new congestion control techniques and the network.


Key Responsibilities

The student will

-- Survey existing low latency TCP congestion control and AQM mechanisms

-- Simulate promising congestion control and network traffic management (AQMs, schedulers, …) mechanisms

-- Adapt Linux congestion control and queuing discipline modules to build prototypes

-- Evaluate simulation and testbed results

-- Submit a final report and give a presentation to the research team


-- Enrolled student in Master in Computer Science or similar

-- Programming experience with C/C++

-- General knowledge about TCP and congestion control

-- Any knowledge or experience with ns2/ns3 is an advantage

-- Language skills: English or Dutch
