Predictive contract mechanisms such as dead reckoning are widely
employed to support scalable remote entity modelling in Distributed
Interactive Applications (DIAs). By employing a form of controlled
inconsistency, a reduction in network traffic is achieved. Previously,
we have proposed the Dynamic Hybrid Strategy Model (DHSM) as
an extension to the concept of dead reckoning that adaptively selects
extrapolation models based on the use of local performance criteria.
In this paper, we formalize the notion of the DHSM as a generalized
framework for network traffic reduction in DIAs, alongside a set of
consistency metrics for use as local performance criteria
