    Switched, Fast, and Gigabit Ethernet - CH 3 - Ethernet, Fast Ethernet, and Gigabit Ethern.. 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.

  • Gigabit Ethernet Gigabit Ethernet
    Gigabit Ethernet Gigabit Ethernet Vijay Moorthy, ([email protected]) Ethernet is the world's most pervasive networking technology. Gigabit Ethernet is the latest version of Ethernet. It offers 1000 Mbps ( 1 Gbps ) raw bandwidth, that is 100 times faster than the original Ethernet, yet is compatible with existing Ethernets, as it uses the same CSMA/CD and MAC protocols. When Gigabit Ethernet enters the market it will compete directly with ATM. This paper presents a survey of Gigabit Ethernet technology.

With Managed and Layer 3 models available, the 24+2+2 switches make adding Gigabit backbones a painless experience. Gigabit Ethernet Without Rewiring: The Professional Series switches utilize WideBand’s robust signaling technology allowing Gigabit connections over Category 5 runs in excess of 200 meters, and even over 100-meter segments of Category 3 cable. The switches have been WGNA Certified to transmit data up to a full 100 meters with a bit error rate of less than 1 per million on all grades of Category 5 cables, ensuring not just connectivity, but full bandwidth on existing network wiring. Breakthrough SPU Technology: WideBand’s Switch Processing Unit (SPU) is integrated to provide a never before seen level of management control while eliminating costly components needed in competing designs. The Managed switch models provide extensive support for VLANs, traffic prioritization, and packet filtering based on Layer 2, 3, and 4 information. Wire-speed Layer 2/3/4 Switching and IP Routing: The WideBand Professional Series switches deliver wire-speed switching and MAC address learning in a fully non-blocking architecture. The Layer 3 models add enterprise-class IP routing at wire-speed as well as QoS provisioning features based on Layer 2/3/4 and IEEE 802.1p tag information. Auto MDI/MDI-X Makes Connecting Easy: All the ports automatically detect straight-through/crossover cable types, eliminating communication problems resulting from cable type mismatches.
