Title: Fault tolerance in distributed systems

Abstract:

One of the key principles of distributed computing is to replicate data and distribute tasks to improve the availability and fault-tolerance. But this distribution poses new challenges, in particular the coordination of processes. To ensure the consistency and proper functioning of the system, distributed entities must exchange information and reach joint decisions, even in the case of breakdowns or unpredictable behaviour. In this context, fault-tolerance becomes a central issue. Distributed systems must continue to operate despite partial failures or abnormal behaviours of certain components.

In my research, I explored two ways to strengthen the resilience of distributed systems:
- The k-agreement, which makes it possible to ensure coordination despite the faults.
- Self-stabilization, which aims to automatically restore the system after temporary disturbances.

In the course of my presentation, I will present the main results achieved in these two lines of research.
