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 acceptance and use in home and office networks. Although the conventional Ethernet technology is low-cost and very high-speed its nondeterministic behavior does not support real-time traffic. In this thesis we present the design, implementation and evaluation of the novel ICN protocol D²RIP (Dynamic Distributed Real-time Industrial Communication Protocol) that was proposed in previous work. D²RIP is a fully distributed protocol over shared-medium Ethernet with COTS (Commercial Off-The-Shelf) hardware and provides real-time message delivery guarantees, supports non-real-time traffic. As a distinctive feature in comparison to other ICNs over Ethernet that only support static allocation of real-time and non-real-time bandwidth, D²RIP allows for dynamic allocation of the network capacity among the participating nodes by exploiting knowledge about the deterministic system behavior of industrial systems.
