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.

The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) allow use of selected Physical Layer devices (PHY) for operation over coaxial, twisted-pair or fiber optic cables. System considerations for multisegment shared access networks describe the use of Repeaters that are defined for operational speeds up to 1000 Mb/s. Local Area Network (LAN) operation is supported at all speeds. Other specified capabilities include various PHY types for access networks, PHYs suitable for metropolitan area network applications, and the provision of power over selected twisted-pair PHY types.

  • Fact Sheet: Single-Pair Ethernet Trade Article
    Fact sheet Single Pair Ethernet Matthias Fritsche – product manager device connectivity & Jonas Diekmann – technical editor HARTING Technology group – October 2016– November 2016 Wireless technology and optical cable have already been often heralded as the future transmission technology. However, simple twisted pair cable based on plain old copper, often pronounced dead, is the most common transmission medium. Simple, robust, and perhaps with 100GBASE T1 soon to be also incredibly fast. From the beginnings of Ethernet in the 1970s, then via diverse multi-pair Ethernet developments with multiple parallel transmission paths, now apparently we are taking a step back. Back to single twisted-pair. With a new protocol and new PHYs transmission rates of up to 10 Gbit/s and PoDL capacities of up to 60 W are no longer a problem. Ultimately one pair is enough. When the team surrounding David Boggs and Robert Metcalf in the 1970s developed Ethernet at the Xerox Palo Alto Research Center (PARC), no one could foresee that this transmission method would develop so dynamically and dominate data transmission worldwide to this day. The original 10BASE5 Ethernet still used coax cable as the common medium. Today, next to wireless and optical cables, twisted-pair cable, often pronounced dead, is the most frequently used transmission medium. Starting in 1990 with 10BASE-T, the data transmission rate of the IEEE standards increased by a factor of 10 approximately every 5 years over 100BASE-TX and 1000BASE-T up to 10GBASE-T. This series could not be continued for the jump to 100GBASE-T, instead however four new IEEE standards were finalized in 2016.

It is the most popular 10-Mbps fiber standard. 10BASE-FP and 10BASE-FB are dead. P means passive; B means backbone. Fast Ethernet 100BASE-T is 10BASE-T with the original Ethernet Media Access Controller (MAC) at 10 times the speed. It allows three physical-layer implementations, all part of IEEE 802.3u: 100BASE-TX, which has two pairs of Category 5 UTP or Type 1 STP cabling and is most popular for horizontal connections; 100BASE-FX, which has two strands of multimode fiber and is most popular for vertical or backbone connections; 100BASE-T4, which as four pairs of Category 3 or better cabling and is not common. Gigabit or 1000-Mb Ethernet is the 1998 IEEE 802.3z standard that includes the Gigabit Ethernet MAC and three physical layers.

In the mid- 1980s, IBM unveiled a competing network technology called Token Ring. You’ll get the complete discussion of Token Ring in the next chapter, but it’s enough for now to say that Token Ring used a physical star topology.

    2016-09-24 Ethernet Basics based on Chapter 4 of CompTIA Network+ Exam Guide, 4th ed., Mike Meyers Ethernet Basics • History • Ethernet Frames • CSMA/CD • Obsolete versions • 10Mbps versions • Segments • Spanning Tree Protocol 1 2016-09-24 Ethernet – Early History • 1970: ALOHAnet, first wireless packet-switched network - Norman Abramson, Univ. of Hawaii - Basis for Ethernet’s CSMA/CD protocol - 1972: first external network connected to ARPANET • 1973: Ethernet prototype developed at Xerox PARC - (Palo Alto Research Center) - 2.94 Mbps initially • 1976: "Ethernet: Distributed Packet Switching for Local Computer Networks" published in Communications of the ACM. - Bob Metcalfe and David Boggs - sometimes considered “the beginning of Ethernet” Ethernet goes Mainstream • 1979: DEC, Intel, Xerox collaborate on a commercial Ethernet specification - Ethernet II, a.k.a. “DIX” Ethernet - (Digital Equipment Corporation) • 1983: IEEE 802.3 specification formally approved - Differs from Ethernet II in the interpretation of the third header field • 1987: alternatives to coaxial cables - IEEE 802.3d: FOIRL, Fiber Optic Inter-Repeater Link - IEEE 802.3e: 1 Mbps over Twisted Pair wires (whoopee!) • 1990: Twisted-Pair wiring takes over - IEEE 802.3i: 10 Mbps over Twisted-Pair – 10Base-TX, 10Base-T4 2 2016-09-24 the Future is Now (next chapter) (and Now is so Yesteryear…) 1995 – Now: speed and cabling improvements • 1995: 100Mbps varieties • 1999: 1Gbps on twisted-pair • 2003-2006: 10Gbps on optical fiber and UTP • 2010: 40Gbps, 100Gbps (802.3ba) - optical fiber or twinaxial cable - point-to-point physical topology; for backbones • 2016, September: 2.5GBase-T, 5GBase-T ? - who knows? What Is Ethernet? • Protocols, standards for Local Area Networks » Ethernet II, IEEE 802.3 • Specifies Physical-layer components - Cabling, signaling properties, etc.
