Celebrating 50 Years of Ethernet
Today, millions of people globally depend on Ethernet. One of the world’s most durable, ubiquitous technologies, the sheer brilliance of its simple design is among the many reasons that Bob Metcalfe received the prestigious A.M. Turing Award earlier this year.
On May 22, 1973 Bob Metcalfe wrote a memo – which included the now famous Ethernet “napkin sketch” – proposing a new type of data transmission method. In the 50 intervening years since that fateful day, Ethernet has become a truly transformative technology, upending connectivity and allowing the free flow of data to all corners of the globe.
In honor of Ethernet’s 50-year legacy, Ethernet Alliance leaders have shared their thoughts on this major milestone and what innovation still lies ahead.
Is Ethernet the Perfect Technology? What Makes It So Resilient?
“Ethernet has succeeded by building a comprehensive, open community that provides the technology that underpins the Internet. It doesn’t attempt to be perfect. It specifies just enough to satisfy the customer need, maintains an intense focus on interoperability, and adapts to changing needs and technologies as they arise.” – Peter Jones, Ethernet Alliance Chair
“Ethernet is so resilient because it has the flexibility to operate over multiple speeds and media supporting a wide range of industries and network types, while maintaining a strict standards creation process to ensure that technologies will interoperate, perform as expected in the real-world, and deliver high-quality user experiences.” – Dave Estes, Ethernet Alliance Board Member
“The key to Ethernet’s success has been its commitment to openness and interoperability, as well as its adaptability. Ethernet constantly evolves to address new use cases – moving data from the cloud to the edge to serve an increasingly smart and connected world.” – Sam Johnson, Ethernet Alliance High-Speed Networking (HSN) Subcommittee Co-Chair
“Ethernet is updatable to support higher bandwidth needs. Specifications for higher rates leverage the architectural understanding gained from the previously defined Ethernet rates. Commonality over Ethernet rates provide for it to be resilient. Expectations are met generation to generation. Innovation is employed when needed such as for providing feasible physical interconnects at the higher rates.” – Jeffery Maki, Ethernet Alliance Treasurer
“Ethernet’s resilience is a testament to its adaptability across multiple interconnect and options and applications. Ethernet is not constrained by cable nor connection, hence its use over a myriad of copper or fibre cables, in homes and offices, across factory floors, in automobiles, and as the backbone of cellular phone networks. This adaptability is not by accident, rather it’s a product of the combined efforts of engineers across the world who come together to maintain and innovate the underlying standards. Due to its adaptability and engineering community oversight, Ethernet is and continues to be the backbone of our connected world.” – David J. Rodgers, Ethernet Alliance Events & Conferences Chair
“Ethernet has never been perfect, but it has been good-enough, and perfection is always a narrow point, not broad-based enough to really succeed. What’s kept Ethernet alive is interoperability at the packet, frame, and behavioral levels while changing radically – from half-duplex to full-duplex, across varied media and speeds.” – George Zimmerman, Ethernet Alliance Technical Chair
What Is the Significance of Ethernet’s 50th Anniversary?
“With this being the 50th year of Ethernet we have much to celebrate. Many technologies have come and gone over the past 50 years while others have “peaked” and are now on the downward slope. Ethernet keeps rising to greater heights. With Ethernet, the best is yet to come!” – Chris Lyon, Ethernet Alliance President
“The world runs on Ethernet. It is an innovation engine for growth and market diversification, with the ability to seamlessly operate between disparate environments to benefit a growing variety of applications and users. Ethernet has established itself as the foundation of networking globally and is likely to remain so for the foreseeable future. This year as we mark Ethernet’s 50th Anniversary, it is the perfect opportunity to celebrate all those who contributed to Ethernet’s success and to appreciate the immense value this resilient technology brings to the world.” – Orshi Abraham, Ethernet Alliance Marketing Chair
“Ethernet and IEEE 802.3 in general constitute some of the world’s best engineers and international organizational principles in work collaboration and development. Its contributions in bringing the world together a little bit tighter than it was 50 years back with efficient and scalable networking technology has brought about change at a global level. The transformative nature of networking technology now impacts us and our communities for the better in countless ways.” – John Calvin, Ethernet Alliance Board Member
“As we mark Ethernet’s 50-year anniversary, it has become the foundational technology used ubiquitously across the whole networking industry. Ethernet’s efficiency and resiliency lends itself to a broad set of applications and while non-Ethernet optimizations might exist, the universality of Ethernet across and between these applications results in its ever broadening adoption.” – Mark Nowell, Ethernet Alliance Advisory Board Chair
“It is truly remarkable to see how Ethernet, born 50 years ago, is still going strong. With its ability to scale and evolve with new standards, Ethernet continues to keep up with every changing need of the marketplace and meet the challenges of today’s applications, such as enterprise, datacenter, service provider, industrial and automotive. As the data being generated in our digital life continues to grow, Ethernet technology will be the networking technology of choice for a seamless digital experience powered by AI/ML.” – Kishore Racherla, Ethernet Alliance Board Member
“The versatility of Ethernet and growth of applications is continuously on the rise. I’m amazed that Ethernet deployments have evolved from office environments to common day use in the home, automobiles, and portable handheld devices providing seamless data connectivity anywhere. I look forward to seeing Ethernet’s evolution over the next 50 years!” – David Tremblay, Power over Ethernet (PoE) Certification Chair
What Are the Greatest Innovations That Ethernet Has Enabled?
“The Ethernet innovation that I am most excited about is Time Sensitive Networking. It is my opinion that this emerging use case will fundamentally change transportation and industrial manufacturing by enabling unprecedented component synchronization and coordination. This could not be possible without the recent enhancements built upon Ethernet over the last few years.” – Carl Wilson, Ethernet Alliance Secretary
“Today, we can solve large problems and get answers to questions through the virtue of being connected one to another – you to me, both of us to others, and all of us to computers and storage. Ethernet is a key part to our interconnectedness. We are much more powerful and capable due to our interconnectedness, as well as more inclusive than ever before. Thank you, Ethernet, for being the fabric of the connectedness between humans. Let us use the power of this fabric for good; for better and more prosperous lives, creating larger knowledge for all by connecting all.” – Pavel Zivny, Ethernet Alliance HSN Subcommittee Co-Chair
What Do you Think the Next Decade Holds for Ethernet?
“The next 10 years with Ethernet hold great promise as we are poised to fully utilize its capabilities. Ethernet will not only monitor/communicate/control connected assets but also will provide power delivery, augmenting applications like Smart Buildings and Smart Factories. As we approach a complete Ethernet footprint from cloud to edge, enabled by technologies like Single Pair Ethernet, we’ll further leverage the transparency and availability of information from all facets of the enterprise.” – Bob Voss, Ethernet Alliance Single Pair Ethernet (SPE) Subcommittee Chair
