SUMMARY

Ever wondered how the devices in your factory, office, or home communicate with each other? This course provides a comprehensive introduction to Ethernet and network infrastructure. The course is structured into five lessons, starting with the basics of Ethernet and moving towards more advanced networking concepts.

This course aims to demystify the world of networking, providing a structured understanding of Ethernet, from its historical roots to the more complex higher-level protocols and technologies used in modern networks. It’s designed to help learners understand both the practical and theoretical aspects of networking, particularly in the context of industrial automation using PROFINET.

But why is this important to you? In today’s interconnected world, understanding network infrastructure is no longer optional; it’s essential. Networking is not just about wires and devices, but about how information flows and connects our world.

This course will enable you to:

Grasp the fundamentals: You’ll learn about the evolution of Ethernet, its use in automation, and the need for integrated solutions. You will understand the ISO/OSI model, the function of each layer, and the differences between connection-oriented and connectionless operations, and examine Ethernet frame structure.
Master Network Infrastructure: You will be able to distinguish between Layer 2 switches and Layer 3 routers and their roles in network segmentation. You will understand how switches operate, including message buffering, address learning and aging, and frame forwarding methods. You will also grasp the concepts of cut-through and store-and-forward switching. Furthermore, you will learn about network topologies.
Achieve proficiency in advanced networking concepts: You’ll gain a deep understanding of Virtual LANs (VLANs) and how they enhance network performance and security. You will explore VLAN tagging and traffic prioritization. The course will cover the Link Layer Discovery Protocol (LLDP) and its role in network discovery.

By the end of this course, you’ll not only understand the nuts and bolts of Ethernet and network infrastructure, but also appreciate how these technologies contribute to building and operating industrial networks based on PROFINET. You will be able to explain how networks operate, how devices communicate, and why it all matters.

About The Author

Pavel Burget is a researcher affiliated with the Czech Technical University in Prague, specifically with the CIIRC (Czech Institute of Informatics, Robotics, and Cybernetics), where he has been heading Testbed for Industry 4.0. His expertise spans industrial communication, including Ethernet-based systems and protocols like PROFINET. He has contributed to the field through various research projects and educational courses that delve into the dynamics of industrial communication systems, focusing on aspects like diagnostics and modeling. He has also been involved in giving Certified PROFINET Engineer courses.

Learning outcomes

By the end of the course, every learner will demonstrate mastery of Ethernet fundamentals by (a) listing at least four historical milestones in Ethernet’s evolution and two automation-specific benefits, (b) matching all seven ISO/OSI layers to their primary functions, (c) classifying six sample traffic flows as connection-oriented or connectionless, and (d) labeling the preamble, destination MAC, source MAC, EtherType, payload, and FCS fields on a blank frame diagram.
By the end of the course, each learner will choose the appropriate Layer 2 switch or Layer 3 router for three given segmentation scenarios and justify each choice; demonstrate message buffering, address learning and aging, and both cut-through and store-and-forward forwarding,; draw line, star, tree, and ring topologies for a specified plant floor and recommend the most fault-tolerant option.
Learners will understand Link Layer Discovery Protocol (LLDP) and its role in network device discovery. They will also be able to describe IP addressing and subnetting, as well as the Address Resolution Protocol (ARP) and how it relates to MAC addresses. Learners will also gain knowledge of how to use ICMP for network diagnostics and describe the differences between UDP and TCP and their applications. Finally, they will be able to describe the purpose and functionality of the Simple Network Management Protocol (SNMP) for network management.
