In this paper the results concerning changes introduced into the architecture of connections of an industrial computer network built on the basis of solutions characteristic of the Industrial Internet of Things were described. We introduce the new solutions improving such properties of industrial networks as: reliability, information security and usage of computational resources available in edge elements. The basic goal of the research was ensuring continuous functioning of the industrial computer network. Isolation of critical elements of the technological process can have far-reaching consequences, including local threats to workers' health and life, and even global technological disasters. Continuity of operation as a consequence of the reliability of the components of an information system is one of its most desirable properties.The offered solution is based on the use of multi-channel reconfigured optical bus that is activated when the basic communication channels fail. In addition, the use of the described solutions for the build of a parallel, heterogeneous computing system based on elements of the Arduino and Raspberry Pi and system servers has been described and evaluated.
This work presents organization, architecture and synthesis as well as analysis of the reconfigurable heterogeneous parallel processing system. Reconfiguration takes place on two levels of the connection network: physical and logical. For its implementation, passive multi-channel optical networks were used. Due to its dynamic nature, the system is designed to handle computational and communication load of an explosive nature and is addressed in the first place to the production sphere of economy. The dynamically combined connection network not only prevents traffic bursts, but also based on the physical and logical circuit commutation gives the possibility of adapting to the existing traffic pattern. Although the described solution is addressed to the optical transmission environment, its effective functioning in the Ethernet networks with circuit switching and partly in wireless networks has been confirmed empirically. The theoretical foundations were verified in the design and construction of a reconfigurable super-microcomputer and the intelligent system detection of attacks addressed to industrial Internet.
