Abstract:
The fourth industrial generation brought both solutions as challenges. It allowed greater efficiency and effectiveness in manufacturing, reducing both costs and wastes. However, it consists in the deployment of innumerable devices for data collection and control processes. This brings challenges such as interoperability between all these heterogeneous systems.
Thus, a group of partners, supported by the European Union, proposed a solution, the Arrowhead Framework. Its aim is to create a framework with a service-oriented architecture (SOA) enabling an abstract collaboration between all these different devices. While in development, the framework does not provide Quality of Service (QoS), which prevents its use in more demanding networks. This limitation was the central problem solved in this project.
This project focus on developing an architecture that provides QoS support in Arrowhead compliant systems. Here the main challenges addressed are the following: developing an architecture capable of working with different communication protocols and technologies; develop an architecture capable of working with an unlimited number of QoS requirements.
During the entire project, its development process consisted in two main iterations: the first was regarding the development of an architecture; the second consisted in the development of a pilot project based on the FTT-SE protocol that could test the architecture developed in the first iteration.
At last, the final product consists in two systems, one for QoS configuration and other for monitoring. These two systems are independent of each other. Regarding QoS requirements, only delay and bandwidth were implemented.
