Paper Abstract

A framework for autonomously controlling resource allocation at the application level in a distributed, heterogeneous multi-tasking SPMD environment called Operator-controlled, distributed resource allocation is motivated and described. The environment requiring such resource allocation is typified by the interactive television environment. In an interactive television environment, applications that are intended to execute within a virtual machine environment on a viewer's integrated receiver decoder (IRD), are encoded and broadcast with the audio-video television program. Different viewers make different choices to cause the application, which is identically downloaded to each IRD, to execute differently, hence comprising a multi-tasking SPMD environment. In current deployments, the IRDs are furnished by the operator who ensures that each IRD has sufficient resources to execute each and every program that is broadcast concurrently; hence, two viewers making exactly the same choices will execute the downloaded application identically. In the future, IRDs are expected to be available at retail stores, purchased by consumers that may choose more or less functionality so long as the IRD has the minimally acceptable functionality according to standards that are currently being developed by the middleware and consumer electronics vendors in conjunction with broadcasters and MSOs.
