The proliferation of mobile computers and wireless networks requires the design offuture distributed real-time applications to recognize and deal with the signijicant asymmetry between downstream and upstream communication capacities, and the sign$cant dispari9 between server and client storage capacities. Recent work proposed the use of Broadcast Disks as a scalable mechanism to deal with this problem. In this papel; we propose a new broadcast disks protocol, based on our Adaptive Information Dispersal Algorithm (AIDA). Our protocol is different from previous ones in that it improves both timeliness and faulttolerance, while allowing for a finer control of multiplexing of prioritized data. We start with a general introduction of broadcast disks. Next, we propose broadcast disk organizations that are suitable for real-time applications. Next, we present AIDA and show its fault-tolerance properties. We conclude with the description and analysis of AIDA-based broadcast disks organizations that achieve both timeliness and fault-tolerance, while preserving downstream communication capacity.
A transfer protocol for organizing air disks for real-time applications, called Adaptive Information Dispersal Algorithm (AIDA), is presented in REF .
