Nokia Internship - Low Latency Congestion Control WebRTC Master student 

Belgium

High latency over the network significantly reduces the quality of experience of real-time applications like gaming. Congestion control protocols, in particular L4S (IETF RFCs 9330-9332), address this challenge.

Today, such noticeable excessive latency episodes do not happen very often, so that they can be endured. However, when the network is continuously utilized for live streaming of high-resolution content on multiple devices, such a fully utilized network condition will happen more frequently, possibly all the time.

This prevents metaverse and remote presence applications from being ubiquitously used, since excessive latency is detrimental to the user experience. Low-Latency Low-Loss Scalable Throughput (L4S) and its Prague congestion control overcome this challenge.
The rate of all applications can be controlled by Prague congestion control using the feedback provided by the network, such that the aggregate fits in the network pipe without incurring additional queueing latency.

Prague congestion control needs to be built on top of existing protocols and stacks of Real-Time (RT) applications. This intern position will be responsible for modifying the WebRTC stack using RT-Prague congestion control for real-time communication and conducting experimental research across different networks (Wi-Fi, 5G, PON, etc.).

What you need for this internship is:

• Basic understanding of WebRTC
• Basic understanding of multimedia coding
• Good understanding of relevant network protocols such as RTP, TCP/IP, etc.
• Good understanding of congestion control algorithms
• Demonstrated software programming proficiency (C/C++/Scripting/Linux)
• Fluency in English (both written and spoken)
