In this paper, we proposed a scheduling method to optimize time-critical traffic using genetic algorithm in automotive ethernet networks. The aims generate transmission schedule minimize end-to-end delay, variation of reception time at the destination (jitter), and bandwidth utilization. These indicators should be simultaneously considered when generating since they are closely related performa...

The synchronization control performance of the Fieldbus system (FCS) is an important guarantee for completion multi-axis collaborative machining tasks, and its accuracy one decisive factors quality. To improve FCS, this paper first makes a comprehensive analysis affecting in FCS. Secondly, by analyzing communication model linear Ethernet, distributed clock compensation method based on timestamp...

The paper addresses performance modelling of safety critical Ethernet networks with special attention to in-car networks. A specific Ethernet/IP based in-car network is considered as use-case. The modelling is based on the analytical method Real-Time Calculus (RTC), providing hard bounds on delay and buffer utilization. We show how RTC can be applied on the use-case network. Furthermore, we dev...

Bridged Ethernet and IP routing and forwarding are without any doubt the most deployed network technologies, mainly because of their robust, low-cost and easy-to-deploy-character. Solutions to provide fast recovery over these technologies are thus a highly desired feature. Fast recovery not only needs a fast switchover (e.g. using IPFastReRoute), but also requires fast failure detection. Howeve...

Ethernet is the most famous type of communication network used for office applications. Currently, networks used on field level and on office level are different due to their specific requirements. Especially for real-time systems, the deterministic behavior of the network is very important. Now Switched Ethernet seems to be applicable also on field level, because collisions can be avoided and ...

AFDX (Avionics Full Duplex Switched Ethernet) is an avionics data network based on commercial 10/100Mbit switched Ethernet. AFDX uses a special protocol to provide deterministic timing and redundancy management providing secure and reliable communications of critical and non-critical data. AFDX communication protocols have been derived from commercial standards (IEEE802.3 Ethernet MAC addressin...

One pilot solution of Ethernet-HDSL gateway in the form of standalone processor controlled system is considered in this paper. Block diagram of hardware with 80C188 processor, MK5032 Ethernet Controller, MK68592 Ethernet Serial Interface, and with HDSL dedicated chipset Bt8953 Framer, Bt8952 Transceiver and Bt8921 Analog Front End is detailed presented. The software organization through LAN, HD...

CAN bus is ISO international standard serial communication protocol. It is one of the most widely used fieldbus in the world. It has become the standard bus of embedded industrial control LAN. Ethernet is the most common communication protocol standard that is applied in the existing LAN. Networked industrial control usually adopts fieldbus and Ethernet network, thus the protocol conversion pro...

It is already state-of-the-art technology to transmit camera images in vehicles at 100 MBit/s over a cost-effective, unshielded twisted pair connection. This technology is known as BroadR-Reach, which is standardized by the OPEN Alliance SIG consortium [1]. The next objective is to use Ethernet as a network for infotainment and driver assistance systems by 2015. Some OEMs predict that Ethernet ...
