Ethernet link speeds of 100 megabits per second or even 1 Gbit/s per second are typical in today’s LANs. When everything is wired to Ethernet LAN very many LAN connections are needed and they consume some power. And the faster the Ethernet connection is, typically more power it consumes. IEEE Spectrum Energy-Efficient Ethernet article tells →
Industrial Ethernet Technologies: Overview is a presentation intended to give an overview over the most important Industrial Ethernet technologies. It is good reading for anyone working with Ethernet and/or automation applications. →
Construction and Use of a Passive Ethernet Tap article provides straightforward instructions on how to construct and use a passive Ethernet tap. It allows you to monitor Ethernet traffic on with any hub or switch and any operating system. A passive Ethernet tap is useful when installing an intrusion detection system (IDS) sensor or when →
Advances in data center technology and Internet usage have pushed enterprises to 10 Gigabit Ethernet (Gbps) links. Services like search engines, carriers, ISPs need even higher speeds. Lacking alternatives to 10-Gbps connections, carriers and enterprises have resorted to using multiple 10 Gbps connection (expensive solution). Projected Internet traffic growth mandates the need for higher speed →
In 1973, Bob Metcalfe sent an internal memo to his colleagues at Xerox proposing a local system of interacting workstations, files, and printers. The devices would all be linked by one coaxial cable, he said, and would run within a local area network. He called the system an Ether Network, or Ethernet. And 36 years →
