The DLR Institute of Communications and Navigation is dedicated to mission-oriented research in selected areas of communications and navigation. Its work ranges from the theoretical foundations to the demonstration of new procedures and systems in a real environment and is embedded in DLR's Space, Aeronautics, Transport, Security and Digitalization programmes.
What to expect
The QUIC transport protocol has emerged as a secure and efficient alternative to TCP, offering built-in end-to-end encryption and authentication. However, this increased security renders QUIC packets opaque to middleboxes, potentially hindering the performance benefits traditionally provided by performance-enhancing proxies. These proxies are particularly valuable in scenarios with lossy WiFi connections combined with high-latency links (e.g., satellite).
This thesis will investigate recently proposed enhancements to QUIC aimed at improving performance in these challenging network environments. The work will involve developing a simulation environment, implementing and evaluating packet loss detection mechanisms, and integrating these mechanisms into a QUIC protocol stack.
Your tasks
- Develop a simulator environment (e.g., using NS3) to evaluate QUIC performance across various network configurations.
- Implement and benchmark schemes for detecting packet loss over end-to-end encrypted QUIC connections.
- Integrate selected packet-loss detection mechanisms into a QUIC protocol stack.
Your profile
- Required:
- Solid understanding of network protocols.
- Strong academic record. - Desirable:
- Experience with the NS3 network simulator.
- Familiarity with the QUIC transport protocol.
- Experience implementing communication protocols.
We look forward to getting to know you!
