Switched Real-Time Ethernet in Industrial Applications - Asymmetric Deadline Partitioning Scheme
نویسندگان
چکیده
This paper presents work on a switched Ethernet network extended to allow for periodic real-time traffic, using earliest deadline first (EDF) scheduling. A scheme of asymmetrically dividing deadlines of real-time channels between the in and outgoing links to/from the switch is proposed (ADPS). The result of the simulations of setting up RT channels over a full-duplex switched Ethernet network is presented. The simulations show that the ADPS performs well when master-slave communication is assumed over the network.

متن کاملDeadline First Scheduling in Switched Real-Time Ethernet − Deadline Partitioning Issues and Software Implementation Experiments
This paper presents work on a switched Ethernet network extended to allow for earliest deadline first (EDF) scheduling. We show by example that asymmetric deadline partitioning between the links of a real-time channel can increase the utilization substantially, still not violating the real-time guarantees. We also report measurements on a software implementation of the switch on an ordinary PC.
متن کاملThesis for the degree of Licentiate of Engineering Switched Real-Time Ethernet for Industrial Applications
The research reported in this thesis has been focused on developing and analyzing how to support real-time traffic over a switched Ethernet network without any hardware or protocol modifications. The work has resulted in a proposed systems model, supporting both real-time and non real-time traffic. Currently this model is intended for a one-switch network, with no shared media. All added traffi...
متن کاملTHESIS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Enhancing the Performance of Distributed Real-time Systems
Advanced embedded systems can consist of many sensors, actuators and processors that are deployed on one or several boards, while having a demand of interacting with each other and sharing resources. Communication between different components usually has strict timing constraints. There is thus a strong need to provide solutions for time critical communication. This thesis focuses on both the s...
متن کاملEDF Scheduling Algorithm for Periodic Messages On Switched Ethernet
In the recent years, there is a strong interest of using switched Ethernet in factory automation. The switched Ethernet offers many attractive features such as large throughput, traffic isolation and full-duplex links. However, although using full-duplex switched Ethernet can limit the collisions to each port, the real-time features may be affected due to the collisions on an output port.This p...
