A software defined hierarchical communication and data management architecture for industry 4.0

Abstract

The Industry 4.0 paradigm alludes to a new industrial revolution where factories evolve towards digitalized and networked structures where intelligence is spread among the different elements of the production systems. Two key technological enablers to achieve the flexibility and efficiency sought for factories of the future are the communication networks and the data management schemes that will support connectivity and data distribution in Cyber-Physical Production Systems. Communications and data management must be built upon a flexible and reliable architecture to be able to efficiently meet the stringent and varying requirements in terms of latency, reliability and data rates demanded by industrial applications, and with particular attention on time-critical automation. To this aim, this paper proposes the use of heterogeneous communication technologies integrated in a hierarchical communications and data management architecture where decentralized and local management decisions are coordinated by a central orchestrator that ensures the efficient global operation of the system. Industrial applications are organized in different tiers where different management strategies are applied to satisfy their different requirements in terms of latency and reliability. The use of virtualization and softwarization technologies as RAN Slicing and Cloud RAN will allow to achieve the flexibility, scalability and adaptation capabilities required to support the high-demanding and diverse industrial environment.

How to Quantify Trust in Your Network Emulator?

“…Computer and telecommunication networks are today involved in all main worldwide applications as telephony, financial transactions, banking, TV, on-demand entertainment services, Internet of Things, to cite a few [1] - [3]. In addition, the fourth industrial revolution, also known as Industry 4.0, pushes for bonding communication networks with the industrial ones with the general aims of improving the performance, the level of automation, the level of efficiency and quality of process and final products [4].…”

Integração Do Sistema Ciber-Físico Para Sistema De Programação, Intertravamento E Controle De Um Reator Batelada

“…Isso significa que para a arquitetura dessas redes, itens como a disponibilidade (reability), topologias dinâmicas, mobilidade, interferência dos sinais e perdas, validação e segurança, terão grande impacto em controle de processos em batelada, mas são aspectos para além do presente trabalho (Li et al, 2017) e (Marcon et al, 2017). Por * https://www.amnytt.no/getfile.php/3901260.2265.akzillql7uuipz/RAMEI+4.0.pdf isso, remete-se a leitura de Lucas-Estañ et al (2018) sobre os requisitos da comunicação, lembrando que os protocolos de comunicação para controle de processo sofrerão rapidamente readequação para Indústria 4.0 A Indústria 4.0 representa a quarta revolução industrial a caminho da internet das coisas, dados e serviços. A inteligência descentralizada ajuda a criar redes de objetos inteligentes e gerenciamento de processos independente, com a interação dos mundos real e virtual representando um novo aspecto crucial do processo de fabricação e produção.…”

Priority-Based Bandwidth Management in Virtualized Software-Defined Networks

“…The Internet of Things (IoT) has brought significant benefits to several application scenarios, such as smart cities [1,2] and smart homes [3][4][5], smart metering [6], robotics [7,8], healthcare [9][10][11], and energy management systems [12]. Moreover, the introduction of IoT in industrial environments, i.e., the so-called Industrial Internet of Things (IIoT) [13][14][15], plays a key role in the Industry 4.0 context where a large number of different kinds of devices cooperate over a heterogeneous communication network [16,17]. The steady increase of both network complexity and sharing of physical resources in Industry 4.0 scenarios raises the need for flexible and efficient resource management solutions.…”
