Abstract

A simulation environment was developed which can assist in the design and evaluation of self-organizing video servers. Three behaviour strategies of video server organisation were investigated by the simulation: a static one and two self-organizing ones with different level of elasticity. We defined measures for different types of system performance. The simulation uses the implementation of the configuration recommendation algorithms that were already introduced in our earlier presentations. These algorithms have been enhanced for the decision on the optimal placement of the server components and videos in the network. The control strategy which calls the recommendation function has to schedule the appropriate actions to create the best realizable configuration from the suggested ones, if any. The results indicate that self-organizing behaviour can bring significant improvement in an environment with restricted resources.
