Method and system of coordinating control point state in a home environment

Abstract

A distributed coordination system for a home network environment provides data and functional coordination among multiple control points in a networked home environment. Data and other services (e.g., events) are duplicated among multiple control points. The duplication allows multiple control points to function independently regardless of other control points. Coordination involves the synchronization of runtime state among multiple entities in the network. The distributed coordination system uses a weak consistency model to replicate data and coordinated functions (e.g., event notification) among heterogeneous controlling devices, such as DVD player, speaker, thermostat, with low overhead in a home network. The data replication and function coordination enable software components and/or users to access them without tying themselves to ensuring certain data on a specific control point. In addition, in case, one or more control points go offline, the replicas on other available control points can continue to serve requests and share state.
