Reliability and security on modern Ethernet networks are key to the planning and designing of a communications network for mission critical communications. The wide variety of features available in Ethernet and TCP/IP (Transmission Control Protocol/Internet Protocol) are often not used. This leads to a network that not only lacks reliability and security, but barely caters for the application for which it is intended, let alone for any future upgrades or expansions.

Spending extra time and effort researching what is available; and properly designing, planning and commissioning the system, will lead to a strong communications network that provides a high level of reliability and security on modern Ethernet networks, and ultimately to savings on maintenance and downtime imposed by the communications network. Safety and productivity will increase making it possible to cater for future upgrades or expansions.


Take note

  • Reliability and security are key to planning.
  • Ethernet offers many advantages, but, like all systems, the planning and design stages are crucial.
  • Reliability and security must be designed into the system.
