Implementation and evaluation of the dependability plane for the dynamic distributed dependable real time industrial protocol ((D₃RIP))

Sezer, Ömer Berat
Dynamic Distributed Dependable Real Time Ethernet Industrial Protocol (D3RIP) is a real time industrial communication protocol that runs over shared-medium Ethernet with COTS hardware. The protocol consists of an interface layer that enables time slotted communication and a coordination layer that guarantees collision avoidance and timely delivery of real time messages generated by the control application. At the current development stage, these two layers of the protocol are fully implemented and tested. The scope of this thesis is the implementation of a new plane for D3RIP to achieve dependability. To this end, mechanisms of fault detection and roll back recovery are applied. The interface of the dependability plane to the existing interface layer and coordination layer is defined. Finally the dependability plane is implemented and integrated to the existing protocol stack. A number of tests under different fault scenarios are conducted to demonstrate the plane functionality.


Implementation and evaluation of a synchronous time-slotted medium access protocol for networked industrial embedded systems

Dynamic Distributed Dependable Real-time Industrial communication Protocol family (D3RIP), has been proposed in the literature considering the periodic or event-based traffic characteristics of the industrial communication networks. D3RIP framework consists of two protocol families: Interface Layer (IL) protocol family, which is responsible for providing the accurate time-division multiple access (TDMA) on top of a shared-medium broadcast channel, and Coordination Layer (CL), which is defined to fulfill the...

The contemporary large-scale and complex industrial control systems such as manufacturing systems, power plants or chemical processes are realized as distributed systems. Since different controller nodes are usually physically distributed, their coordination and information exchange is commonly realized via industrial communication networks (ICNs). In the last decade, there is an ongoing research effort in both academic and industrial fields to employ Ethernet for industrial communications due to its wide a...
A simple and effective mechanism for stored video streaming with TCP transport and server-side adaptive frame discard
Gurses, E; Akar, Gözde; Akar, N (Elsevier BV, 2005-07-15)
Transmission control protocol (TCP) with its well-established congestion control mechanism is the prevailing transport layer protocol for non-real time data in current Internet Protocol (IP) networks. It would be desirable to transmit any type of multimedia data using TCP in order to take advantage of the extensive operational experience behind TCP in the Internet. However, some features of TCP including retransmissions and variations in throughput and delay, although not catastrophic for non-real time data...
A longest path problem for evaluating the worst case packet delay of switched ethernet
Schmidt, Klaus Verner; Schmidt, Şenan Ece (2010-07-09)
In the recent years, the use of real-time Ethernet protocols becomes more and more relevant for time-critical networked industrial applications. In this context, this paper presents a method to compute the worst-case packet delays on switched Ethernet. Based on an evaluation of the packet delays at each switch port and the network topology, we construct a weighted directed graph that allows to find the worst-case end-to-end packet delay by solving a conventional longest-path problem.
Tool support for worst case end to end delay analysis of AFDX networks
Efe, Orhun; Bazlamaçcı, Cüneyt Fehmi; Department of Electrical and Electronics Engineering (2016)
Avionics Full Duplex Switched Ethernet (AFDX) is among the major technological components used in avionics systems. Since its publication, AFDX has spread out rapidly and has been deployed in major aircrafts such as Airbus A400M, Boeing 787, Bombardier C Series, etc. In AFDX networks, data is exchanged between end systems by utilizing tunnels. For certification purposes, finding a safe upper bound is required in transmission process. UPPAAL is already shown to be useful for performing such a delay analysis ...
