Over the years, Ethernet switches have become a standard in commercial and industrial applications. They are used to integrate different communication channels within the facility or organization for information centralization and management. Although they work with the same concept of transmitting Ethernet frames between the devices that are connected to them, they largely differ in their construction, design, and implementation. First, the industrial switches have a ruggedized construction and they are designed in adherence to industry standards. Today, their utility is proven in various industries in military and defense. The military Ethernet switches, in comparison to commercial switches, assure reliable, safe, and consistent communication in challenging environments. This paper analyzes the differences between military ruggedized Ethernet switches and commercial Ethernet switches. It also focuses on the applications of military ruggedized Ethernet switches and their adherence to MIL standards.
