“The reason it has proven to be such an enduring foundational technology over the years is because of the IEEE 802.3 community’s vigilance to keep the standard current with its users’ real-world needs.”Īdded Wael William Diab, Vice Chair of the IEEE 802.3 working group, Chair of the revision task force, and Senior Technical Director at Broadcom: “IEEE 802.3 is constantly being refined to address new challenges and applications. “For decades now, Ethernet has provided the flexible connectivity foundation on which application innovation and the bandwidth explosion have been based,” said Brad Smith, Senior Vice President and Chief Analyst at, an optical transceiver and high-speed interconnect market research firm. Amendments addressing 10 Gbps Ethernet Passive Optical Networks (EPONs), energy efficiency, extension to 40 Gbps and 100 Gbps speeds while maintaining compatibility with previously installed IEEE 802.3 interfaces, enhanced support for loss-sensitive applications, and time synchronization are among those incorporated into IEEE 802.3-2012.

The new IEEE 802.3 revision incorporates various technical updates and enhancements and consolidates a host of amendments to the base standard that was approved since IEEE 802.3’s last full revision, in 2008. IEEE 802.3’s relevance continues to grow multidimensionally to address additional media types, bandwidth speeds, and protocols. And that cycle of innovation continues today.” The standard has helped spawn whole new business models, industries, and ways of life. “When Ethernet networking was conceived in the 1970s and the IEEE 802.3 standard was first published in 1985, its founders could not possibly have foreseen the global transformation that their ideas and efforts would ultimately set into motion.
“IEEE 802.3 technologies and the varied Ethernet networks that they enable are found everywhere, and the standard’s application horizon continues to expand,” explained David Law, Chair of the IEEE 802.3 Ethernet Working Group and distinguished engineer with HP Networking. IEEE 802.3 defines wired connectivity for the Ethernet local area, provides access to metropolitan area networks around the world, and expands Ethernet to address new markets, bandwidth speeds, and media types. Hot off the press is the news that the IEEE 802.3-2012 “Standard for Ethernet” was approved.

Our focus in this discussion is to provide an update on recent advancements to learn more about choosing the right switched fabric for your embedded application, check out the following white paper: Serial Switched Fabrics, written by GE Intelligent Platforms, /news-events/detail/2884.Įthernet is under the IEEE’s guidance specifically, the IEEE 802 LAN/MAN Standards Committee (develops and maintains the family of Ethernet specifications.
Each has features that make it more or less suitable for specific applications. The top serial switched fabrics specified in VITA technologies include Ethernet, PCI Express, Serial RapidIO, and Infini-Band. Let us take a look at the status of the major contenders and what each of them has on their road map. Each of them has found its niche, but they still must undergo evolutionary changes to hold their places in the market. Though the list of competing fabrics has become clearer the past several years, there are still several choices. Serial switched fabrics are the blades interconnect protocols of choice for high-performance computing.
