In 1973, Robert Metcalfe wrote a memo that would serve as the founding concepts for the technology that we now know as Ethernet. Xerox Parc assigned Robert Metcalfe with the task of connecting a group of personal computers to a printer. Along with his co-inventor David Boggs, Robert Metcalfe invented the cabling technology that would transform a computer from a static workstation to a dynamic host that could communicate with other computers. It was not until 1979 that IEEE fully standardized the 802.3 Ethernet standard. The first 802.3 Ethernet standard specified for 10 Mbps using coaxial cabling (known as thicknet) but twisted copper pairs proved more efficient and quickly replaced coaxial cabling. But Ethernet’s versatility has far outgrown its original use-case. Ethernet is more than twisted pair copper terminated with an RJ45 connector. The Ethernet Alliance defines Ethernet as a wired technology that supports a variety of media/medium including backplanes, twisted pair, twinax, multimode fiber and single-mode fiber [2016EthernetRoadMap.pdf]. These additional iterations enable Ethernet to provide speeds beyond the traditional 1 Gigabit rates that end-users are traditionally familiar with. Ethernet can deliver terabit speeds to Metropolitan Area Networks (MANs) as well as core networks such as hyperscale datacenters. This rare footage, now part of the Computer History Museum, showcases an early advertisement showcasing Ethernet. (Note the lack of an RJ45 connector!) Xerox’s advertisement envisions Ethernet as the panacea to data information overload (little did they know it would only augment it). But it was its inventor, Bob Metcalfe's, entrepreneurial grit (not Xerox) that established Ethernet as the plumbing pipes of the Internet.
