Exploring an Information Framework for Consistency Maintenance in Distributed Interactive Applications

Consistency maintenance in Distributed Interactive Applications (DIAs) is subjected to network characteristics such as limited bandwidth and latency. Predictive contract mechanisms are techniquesthat compensate for the effect of network latency by extrapolating future entity states from historical records. These approaches trade inconsistency within human perceptual limits for reduced network traffic and latency. This paper explores the use of an information metric to analyse the effect of network latency on remoteconsistency and thus establishes a novel framework to modelpredictive contract mechanisms as a lossy information sharing process. Such a perspective facilitates a novel explicit analysis of the trade-off between network traffic and inconsistency.
