Some ideas on support for fault tolerance in COMANDOS, an object oriented distributed system

The distributed systems group in Trinity has been concerned with fault tolerance for a number of years and are now turning our attention to the topic with renewed interest (and urgency). Specifically we are concerned to provide mechanisims for fault tolerance in the Oisin kernel - the local implementation of the COMANDOS object oriented distributed system. This short position paper outlines our expertise gained to date, some of the lessons we have learned and the avenues which we are currently investigating in order to make Oisin reliable.
