Future tactical communications involves high data rate best effort traffic working alongside real-time traffic for time-critical applications with hard deadlines. Unavailable bandwidth and/or untimely responses may lead to undesired or even catastrophic outcomes. Ethernet-based communication systems are one of the major tactical network standards due to the higher bandwidth, better utilization, and...
This paper is presenting how teleprotection applications via packet switched wide area networks can be implemented guaranteeing required application specific performance parameters. The following different approaches are analyzed for differential protection: a. ITU-T compliant standard circuit emulation (CE) using SAToP/ CESoPSN. b. A novel approach of CE technology, using explicit clocks, developed...
With the increasing deployment of large-scale distributed packet networks in the industry, highly reliable and precise clock synchronization gains even more importance to ensure timeliness of the exchanged datagrams. Design for reliability, robustness and availability should optimally be taken into account for the architecture of the synchronization subsystem as high-level redundancy schemes are limited...
In-car networks based on Ethernet are expected to be the first choice for future applications in the domain of info-and entertainment. However, the full benefit of a technologically integrated in-car network will only become rewarding with an Ethernet-based backbone, unifying several automotive domains in a single infrastructure. Today, there is remarkable interest in the IEEE 802.1 Audio/Video Bridging...
Industrial Ethernet is gradually becoming pervasive in the automation field. EtherCAT is one such technology, combining high real-time performance with a rich functionality set. Besides that, EtherCAT offers short cycle times, accurate time synchronization, redundancy and high data throughput. Most EtherCAT applications are in the 500–1000μs domain. There are only few EtherCAT master implementations...
Avionics Full Duplex Ethernet (AFDX) is a well-established backbone network with wide usage in all current aircrafts, with its first usage onboard the Airbus A380. It was initially defined by Airbus and internationally standardized by ARINC (664 Part 7). The key features are 802.3 Ethernet compatibility, static routing based on a virtual link concept, reserved bandwidth with granted bandwidth allocation...
