Ethernet switches are the ubiquitous building block of any intelligent network. Ethernet technology is deployed in virtually every organization’s data center. Wide Area Networking (WAN) and Metropolitan Area Networking (MAN) providers need to provide their customers with Ethernet services. Ethernet has also become the de facto networking technology in industrial automation even in mission-critical local →
The growing importance of cloud computing along with the increasing utilization of unified data/storage connectivity and the advent of server virtualization have elevated the popularity of 10Gbps Ethernet.There are several connectivity options are available for 10Gbps Ethernet, both over optical fiber and copper cables. 10GBase-T Technology Revisited article tells that the lack of economical cabling →
I still like to follow what is happening IEEE is doing on Ethernet standardization, although there has been around 10 years since I last time was part of the process. I was participating in Ethernet in the first mile (EFM) standardization work at years 2000-2001 (at that time I worked for Nokia). There is always →
Hardware developers familiar with the history of Ethernet in the enterprise may find themselves overwhelmed by the service diversity and complexity which must be addressed in applications for the local exchange carrier, long-haul or inter-exchange provider, and wireless operator. Analyze service complexity in a common Ethernet infrastructure article tasks Ethernet is called upon to perform →
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 →
