Abstract:
This work demonstrates the potentialities of a simulated fault-injection based approach to the design of effective recovery strategies for distributed multimedia systems. Fault injection experiments are conducted on a simulated model of a real prototype of a Video on Demand (VoD) distributed application. The model is built by combining the basic objects of a simulation tool for dependability (reliability, availability, and performability) prediction and evaluation of distributed multimedia systems, currently under development at the University of Naples. Results demonstrate that the approach, and the tool are suited for evaluating the effectiveness of potential recovery strategies, in the early stages of the design process, when the architecture of the system has not been defined yet, or in the early prototype phase, when some components have been already implemented, but there is still potential for alternative solutions and/or substantial modifications. 1 Application Architecture The application used as a case study is called Distributed Video Architecture (DiVA) and is currently under development at the University of Naples. DiVA [4] is an interactive client-server system for retrieval and real-time delivery of video sources from a remote distributed database.
