Think 100 Gbps Ethernet is The Coming Thing? You ain’t seen nothing yet: In 2025 you’ll run 100 Gbps on the server, 400 Gbps on the switch and 1 Tbps on the router. This is what the Ethernet Alliance’s 2015 roadmap expects to be able to deliver. Between now and 2020, the group expects to →
How low can Ethernet switches prices go? In small unmanaged 8 port 10/100M 5 or 8 port switches typical price is around 15-25 Euros (around 2-3 Euros per port). But there are even cheaper Ethernet switches. Netwjork Tenda S108 SOHO kytkin/switch jossa 8 porttia is a very cheap 8 port 10/100M switch that costs only →
This week started with news titled D-Link Router backdoor vulnerability discovered and Back door found in D-Link routers. This rather worrying security vulnerability on several D-Link branded modem routers made me to check my system because I use D-Link firewall. But let’s start from the basics. Because D-Link device was on news, where is a →
I have written earlier about USB and Ethernet audio. Audio networking offers key benefits, like a dramatically reduced cable infrastructure, easy audio signal copying and routing, etc.. Control Geek blog has just a new interesting posting related to this topic: Dante, AVB, and a Visit to the AVnu Testing Lab. Dante, AVB, and a Visit →
Over the last decade the way we find, store, and listen to music has undergone a huge change. Online media has changed many aspects of the audio industry, but some things just don’t change. The debate over audio quality still goes on. Ethernet AVB, USB Audio Class 2.0 aid audio quality article discusses on some →
Twisted pair Ethernet (10 and 100 Mbit/s) uses two pairs of wires. Ethernet (10 Mbit/s works well, 100 Mbit/s sometimes) can be run on the old telephone wiring. There some years ago quite a bit of interest in reusing old telephone wiring for Ethernet connections. Reusing old installed wiring for Ethernet works usually well if →
Twisted pair Ethernet (10 and 100 Mbit/s) uses two pairs of wires. 10BASE-T Ethernet was designed to be be used on CAT3 quality wiring. 100BASE-TX was designed to be used with CAT5 wiring or better. Since the early 2000s most new structured cable installations are built with Category 5e or Category 6 cable. There are →
In the modern world sensors are used for recording everything from exhaust gas temperatures to the electrical activity in a human heart. Direct wiring methods are commonly used for simple on-off device control, where a circuit is either open or closed. Likewise, digital sensors are usually wired directly to monitoring panels in the world of →
Cracking open a 24-port switch so you don’t have to posting at Hackaday point to an article Tear-Down of an HP ProCurve 2824 Ethernet Switch that is worth to check out for everybody interested in device tear-downs and Ethernet. Tear-Down of an HP ProCurve 2824 Ethernet Switch article shows you the technology inside a managed →
Ethernet is 40 years old. In 1973, Bob Metcalfe sent an internal memo for a LAN design. Ethernet at 40: Its daddy reveals its turbulent youth is a well worth to read article that tells about the youth of Ethernet and why it became the dominant LAN standard. It also tells how much Ethernet owes →
