Ethernet and Sonet are on a crash course. With Ethernet continuing to push its way out of the enterprise into the access and metro sectors, developers of Sonet equipment are being pushed to map ...

Terms can sometimes play tricks on the mind. Take EtherNet/IP, for example. Many people will read “IP” as internet protocol and think that EtherNet/IP refers to plain old, standard industrial Ethernet ...

In the last RTFM we saw how IP packets are transmitted across the network. Here, we tackle Ethernet and see how packets are encapsulated and used. To explain fully the way in which IP packets are used ...

For the first time, evangelists for six of the leading industrial Ethernet networking protocols sat side by side to present their protocols. Attendees at The Automation Forum asked questions and got ...

Figure 1. A typical iSCSI SAN. There has been much discussion (and a good dose of confusion) about the term “iSCSI” over the last year. This relatively new protocol for storage technology offers many ...

The technology started with 10-Mb/s coax cabling (10BASE5). Twisted-pair and RJ45 connectors quickly replaced that, while fiber optics was implemented for high-speed, long-distance communication.

While there are many ways to connect components in embedded systems, the most prominent are the high speed serial standards of Ethernet, PCI Express, and RapidIO. All of these standards leverage ...

RapidIO, PCIe, and Ethernet each offer unique benefits. We explain how each technology works, and examine its strengths and weaknesses. We also show why RapidIO is often the best choice for embedded ...
