Title: A Quality-of-Service (QoS) based approach for the communication support in network-based control systems: an on-going project
Issue Date: 2004
Abstract: Due to the increased availability of low cost network technology, the implementation ofNetwork-based Control Systems (NCS) is becoming widely accepted. Current NCS areusually supported by small-dedicated communication networks (known as fieldbusnetworks) operating in access-controlled mediums, which are able to guarantee thedelivery of control data within known and bounded delays.It is however foreseeable that, access-uncontrolled networks (such as packet-basednetworks) will play an important role in future NCS. In this paper, we present an ongoingproject, proposing the use of a QoS architecture to implement NCS built uponshared networks with uncontrolled access, i.e., considering communication environmentssubject to unknown disturbances.Within this project, several QoS architectures for packet-based networks are looked atcarefully, such as the IntServ and the DiffServ architectures and the Multi-ProtocolLabel Switching (MPLS) and the Constraint Based Routing strategies. Such multipleQoS architectures will be evaluated through the use of an experimental platform enablingthe implementation and evaluation of network-based control systems .
