2019 Laprie Award Winners

The IFIP 10.4 working group on Dependable Computing created the award in honor of the late Jean-Claude Laprie in 2011. It recognizes outstanding papers that have significantly influenced the theory and/or practice of Dependable Computing. For 2019, the award committee has selected:

Huang, Y., Kintala, C., Kolettis, N., & Fulton, N.D. Software Rejuvenation: Analysis, Module and Applications. In Proceedings of the 25th International Symposium on Fault-Tolerant Computing (FTCS), Pasadena, CA, USA (June 1995), 381-390.


Software Rejuvenation: Analysis, Module and Applications by Yennun Huang, Chandra Kintala, Nick Kolettis, and N. Dudley Fulton is a seminal paper that established the idea of proactively restarting software systems to avoid issues related to software aging as a mainstream fault-tolerance technique. While the value of periodic restarts had long been part of the computing folklore, this was the first paper to provide both a sound scientific framework for the approach and compelling evidence of its value as a technique for increasing availability in production systems. The impact of the paper on the field has been profound. On the research side, it created a new area and established what is still an active community investigating various aspects of software rejuvenation. On the practical side, the technology it originated is now applied routinely in areas as diverse as telecommunications systems, web applications, network devices, and spacecraft software. This publication is an excellent example of a ground-breaking paper, and is well-deserving of this award.
