Temporal Interactions of Intervals in Distributed Systems

Ajay D. Kshemkalyani
1996 Journal of computer and system sciences (Print)  
In a space time view of a distributed system, each point in space has its own time axis. This paper studies the interaction of intervals at different spatial points in a distributed system.  ...  The diverse suite of temporal relations between intervals included in our results provides much greater flexibility than do Lamport's relations to model interprocess interaction in a distributed system  ...  While Hamblin's result is applicable to a study of interactions of intervals in a uniprocessor system, it is inadequate for modeling the interactions of intervals in distributed systems.  ...
