Real-time event broker II


This deliverable presentsthe current state of the design of the real-time event broker infrastructure of the COMPOSITION systemat month 26 in the project.During the first year of the project,work was focused on evaluationof alternative implementation mechanisms, choice of protocols and thedesign of the real-time event broker integration with other components.During the second year of the project, implementationand deploymentin test and pilot environments and scalability design have been performed, the information models have been refined, and extensions to the broker has been developed.The real-time event broker (referred to in this document and other COMPOSITION documentation as the Message Broker)is a principal componentin realizing both of COMPOSITION’s main goals. The first goal is to integrate data along the value chain inside a factory into one integrated information management system (IIMS) combining physical world, simulation, planning and forecasting data. The goal of the IIMS is to enhance re-configurability, scalability and optimisation of resources and processes inside the factory andoptimise manufacturing and logistics processes. Here the broker creates a secure, loosely coupled and scalable way to distribute data in the system at near real-time speeds. The second goal is to create a (semi-)automatic ecosystem, which extends the local IIMS concept to a holistic and collaborative system incorporating and interlinkingboth the supply and the value chains. This should be able to dynamically adapt to changing market requirements. Here, the broker provides the communication between the actors in this marketplace. These two brokers are separate instances of the same component. RabbitMQ is the core of this component. It is a widely used, open, standards-based product previouslyused in FITMAN(EU FP7 2013-2015)2.It provides support for multiple protocols and horizontalscalability. COMPOSTION significantly contributes to this open and scalable design. Throughadapters developed in COMPOSITION, we extend RabbitMQ withan integrated security framework and using blockchain-based log functionalityon multiple levels. The Message Brokerhas been deployed as a set of Docker images at the COMPOSITION intra-factory test serverand intra-and inter-factory sites
