Recent technological developments are pulling fieldbus networks to support a new wide class of applications, such as industrial multimedia applications. To enable its use in this kind of applications the TCP/IP suite of protocols can be integrated within a fieldbus stack, leading to a dual-stack approach that is briefly outlined in this paper. One important requirement that must be fulfilled by this approach is that the hard real-time guarantees provided to the control-related traffic (“native” fieldbus traffic) are kept. At the same time it must also provide the desired quality of service (QoS) to IP applications. The focus of this paper is on how, in such a dual-stack approach, QoS can be efficiently provided to IP applications requiring quasiconstant bandwidth.
