"Booting Clock Synchronization in Partially Synchronous Systems with Hybrid Process and Link Failures";
in: "Distributed Computing", Springer-Verlag, 2007, S. 115 - 140.



Kurzfassung englisch:
This paper provides description and analysis of a new clock synchronization algorithm for synchronous and partially synchronous systems with unknown upper and lower bounds on delays. It is purely message-driven, timer-free and relies on a hybrid failure model incorporating both process and link failures, in both time and value domain. Unlike existing solutions, our algorithm works during both system start-up and normal operation: Whereas bounded precision (the mutual deviation of any two clocks) can always be guaranteed, accuracy (clocks being within a linear envelope of real-time) and hence progress is only ensured when sufficiently many correct processes are eventually up and running. By means of a detailed analysis, we provide formulas for resilience, precision and envelope bounds.
