Page 1 of 36 [Figures are not included in this sample chapter] Switched, Fast, and Gigabit Ethernet - 3 - Ethernet, Fast Ethernet, and Gigabit Ethernet Standards This chapter discusses the theory and standards of the three versions of Ethernet around today: regular 10Mbps Ethernet, 100Mbps Fast Ethernet, and 1000Mbps Gigabit Ethernet. The goal of this chapter is to educate you as a LAN manager or IT professional about essential differences between shared 10Mbps Ethernet and these newer technologies. This chapter focuses on aspects of Fast Ethernet and Gigabit Ethernet that are relevant to you and doesn’t get into too much technical detail. Read this chapter and the following two (Chapter 4, "Layer 2 Ethernet Switching," and Chapter 5, "VLANs and Layer 3 Switching") together. This chapter focuses on the different Ethernet MAC and PHY standards, as well as repeaters, also known as hubs. Chapter 4 examines Ethernet bridging, also known as Layer 2 switching. Chapter 5 discusses VLANs, some basics of routing, and Layer 3 switching. These three chapters serve as a precursor to the second half of this book, namely the hands-on implementation in Chapters 8 through 12. After you understand the key differences between yesterday’s shared Ethernet and today’s Switched, Fast, and Gigabit Ethernet, evaluating products and building a network with these products should be relatively straightforward. The chapter is split into seven sections: l "Ethernet and the OSI Reference Model" discusses the OSI Reference Model and how Ethernet relates to the physical (PHY) and Media Access Control (MAC) layers of the OSI model.

    Toward Higher-Speed Modular Interconnection Compatibility Contributors: Greg McSorley, Amphenol John D’Ambrosia, Dell Executive Summary Driven by the ever-increasing server speeds and storage explosion, enterprises today are migrating infrastructures from 10 Gb/s to 40 Gb/s and establishing a framework for 100 Gb/s systems. A basic building block of this framework is the development of a high-speed modular (HSM) port approach, which will enable data centers to pick and choose the physical-layer specifications that will deliver the performance needed at the right cost point. The HSM concept has been implemented for both 40 Gigabit Ethernet (GbE) and 100GbE, allowing networks to continue to scale with rate without causing major architectural changes. This technical brief will provide an overview of the HSM approach, helping users take maximum advantage of the 40GbE and 100GbE architecture to come up with the appropriate interconnects and cost-effectively select from multiple vendors where interoperability can be ensured. Introduction IEEE 802.3™-2012 “Standard for Ethernet” defines a number of physical-layer specifications, including 40GBASE-CR4 and 100GBASE-CR10, which target twin-axial cabling, as well as optional electrical interfaces. The first of those optional interfaces, an Attachment Unit Interface (AUI), is intended for retimed applications, while the Parallel Physical Interface (PPI) is designed for non-retimed applications.1 HSM is envisioned as a kind of universal port type for the globally expanding Ethernet ecosystem. This powerful concept is being leveraged by system vendors to create ports capable of supporting a single form factor that can be populated with different modules that are each capable of supporting a specific physical-layer specification, such as multi-mode fiber, single-mode fiber, twin-axial copper cable or even an active cable solution.

    ethernet alliance DesignCon 2006 10 Gigabit Ethernet on Unshielded Twisted-Pair Cabling Moving 10 Gigabit Ethernet into a Volume Platform Version 1, February 2006 Authors: Paul Langner, Aquantia Corporation [email protected] Bill Woodruff, Aquantia Corporation [email protected] Blaine Kohl, Tehuti Networks [email protected] ethernet alliance | p.o. box 200757 | austin, tx | 78720-0757 | usa www.ethernetalliance.org ethernet alliance Page 2 abstract Two challenges exist as 10 Gigabit Ethernet (10GbE) is extended beyond its initial role. Achieving 10Gbps on copper unshielded twisted pair (UTP) cabling is a signifi- cant technical achievement. Meeting the application’s requirements for low power is also needed for 10GBASE-T, more commonly known as 10 Gigabit Ethernet over UTP cabling, to meet its full potential. Near Shannon limit performance leverages multiple techniques, from pre-coding to a DSQ128 multi-level signaling. One of the most intriguing technologies is the Error Control Code, Low Density Parity Check (LDPC). Together these techniques permit operation at close to the Shannon limit. There are tradeoffs involved in achieving this goal, but power and latency are kept at acceptable levels. introduction The IEEE began to study 10 Gigabit Ethernet in 1998, and in June 2002, published the first 10GbE standard, IEEE Std. 802.3ae™-2002, a fiber-only solution. As Ethernet continues its on-going expansion, a cost effective, backward-compatible copper interconnect for 10GbE stood out as a major challenge to be solved. The creation of the 10GBASE-T draft standard, IEEE P802.3an, for operation over un- shielded twisted pair (UTP) copper cabling is a critical element which is being devel- oped within the 802.3an task force.

  • Ethernet Alliance Expands Subcommittee Roster by Three
    ETHERNET ALLIANCE EXPANDS SUBCOMMITTEE ROSTER BY THREE New 400GbE, Access Networking, and Roadmap subcommittees a reflection of accelerating Ethernet evolution and advancement BEAVERTON, OR, May 6, 2013 – The Ethernet Alliance, a global consortium dedicated to the continued success and advancement of Ethernet technologies, today unveiled three new subcommittees: 400GbE, Access Networking, and Roadmap. Complementing the organization’s lineup of highly targeted and focused subcommittees, the approval and formation of the new groups parallel the rapidly accelerating changes taking place within the global Ethernet ecosystem. “We’ve reached an inflection point in Ethernet’s timeline; there’s a cascade of exciting developments – the race to 400GbE, for example – that are advancing this seminal technology farther and faster than at any other time in its 40-year history,” said John D’Ambrosia, chairman, Ethernet Alliance, and chief Ethernet evangelist, Dell. “It’s moments like this when we have a wave of emerging technologies and projects that the need for organizations with the capacity for industry consensus building, such as the Ethernet Alliance, is never clearer. All of the dynamic energy we’re currently seeing in the Ethernet ecosystem is being reflected internally; as the Ethernet Alliance continues to grow and expand globally, we’re perfectly positioned to coalesce these new innovations and momentum into concrete successes.” Ethernet Alliance subcommittees help advance standards-based Ethernet through a variety of initiatives and activities like technology incubation, development of new standards frameworks, and conducting of market studies. The three new subcommittees join eight existing committees spanning a broad spectrum of technologies and segments, including BASE-T, Carrier Ethernet, Ethernet in the Data Center, Energy Efficient Ethernet (EEE), 40G and 100G Ethernet, Next Generation Enterprise Cabling, Power Over Ethernet (PoE), and Higher Speed Modular IO.

  • Ethernet Alliance's Collaboration with UL Expands Worldwide Footprint Of
    Ethernet Alliance’s Collaboration with UL Expands Worldwide Footprint of Industry-Leading PoE Certification Testing Program BEAVERTON, OR, AND HONG KONG, FEBRUARY 23, 2021 – The Ethernet Alliance, a global consortium dedicated to the continued success and advancement of Ethernet technologies, and UL, the global safety science leader, today announced the availability of Ethernet Alliance Power over Ethernet (PoE) Certification testing in UL’s laboratory in Taipei, Taiwan. “UL has a long history of providing safety and performance testing services for the global telecommunications industry. The collaboration with Ethernet Alliance will help us to strengthen our support for the rapidly growing PoE industry’s by combining Ethernet Alliance’s testing resource and our scientific expertise to help customers grow in confidence and gain market access,” said Eric Bulington, director of global business development for UL’s Wire & Cable division. The Ethernet Alliance PoE Certification program is crucial to minimizing interoperability issues and fueling a positive user experience with IEEE 802.3 standards-based PoE. With IEEE standards defining more efficient and robust methods of delivering electrical power along with data from power sourcing equipment (PSE) such as Ethernet switches to powered devices (PDs) via Ethernet cabling, the world is amid sharp growth in the number and variety of PoE-powered devices, including wireless access points, phones, cameras, speakers, LED lighting and many others. Dell’Oro Group predicts nearly 780 million Ethernet switch PoE ports will ship from 2021 to 2025. Based on a test plan developed by many of the same individuals who helped write the IEEE 802.3 PoE standards, the Ethernet Alliance PoE Certification program enables simple and clear identification of those PSE and PD products that will successfully work together and dependably deliver the differentiating power and efficiency benefits promised by IEEE-standardized PoE.
