Description
Summary:Industrial media control applications require on-line QoS management services to dynamically allocate the bandwidth among the entities that compose the distributed application. The bandwidth distribution mechanism assigns bandwidth to each entity based on the QoS requirements and the current state of the network. However, mapping that bandwidth into operational parameters that serve the scheduling model of the network is not straightforward. Due to systems constraints, this is not a bijective function, therefore multiple solutions may mathematically represent the same bandwidth value but lead to different application performance levels. This paper presents two mapping algorithms and analyzes their performance in this context. The obtained results show that the selection of this mapping algorithm is highly relevant for the application performance.
