Supporting end-to-end quality of service properties in OMG data distribution service publish/subscribe middleware over wide area networks
We demonstrate how DDS scheduling overhead contributes to processing delays. The evaluation of the architecture shows that proposed QoS approach shows how DDS services enhance the schedulability and the predictability of DRE applications. The framework improves data delivery over heterogeneous IP networks, and confirms its potential impact providing network-level differentiated performance. We examine how DDS QoS mechanisms impact bandwidth protection in WANs. The customized implementations of DDS can achieve lower end-to-end delay.
