This annual technical report presents the current state of the
project OPTIMUS 01 IR 605 'Optimization, Modeling and
Implementation of Distributed Multimedia Systems', which is a
research activity at St. Petersburg Technical University,
Distributed Computing and Networks Department in collaboration with
Stuttgart University, Distributed Systems Department. The project is
supported by a research grant of the 'Bundesministeriums für
Bildung, Wissenschaft, Forschung und Technologie' of Germany.
The project is dedicated to the problems of configuration and
synchronization management modeling, analysis, optimization and
development for distributed multimedia systems. The annual report
presents the methods, models, algorithms, mechanisms, and a
simulation tool developed for analysis, optimization and design of
distributed multimedia application configuration management,
negotiation and resource reservation protocol, and adaptive
synchronization protocol, that support configurable distributed
multimedia applications. Results of computational experiments
conducted for complexity and accuracy evaluation of algorithms
proposed are presented as well. Problems of testbed platform
development and implementation for configuration and synchronization
management of distributed multimedia systems are discussed. The
research results obtained are oriented on the further development of
CINEMA (Configurable IntEgrated Multimedia Architecture) that was
designed at the Distributed Systems Department of Stuttgart
University and supports development and control of multimedia
applications with arbitrary processing topologies consisting of
multiple data sources and sinks as well as arbitrary intermediate
processing stages.
