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

Glossaire Des Protocoles Réseau
Glossaire des protocoles réseau - EDITION LIVRES POUR TOUS - http://www.livrespourtous.com/ Mai 2009 A ALOHAnet ALOHAnet, également connu sous le nom ALOHA, est le premier réseau de transmission de données faisant appel à un média unique. Il a été développé par l'université d'Hawaii. Il a été mis en service en 1970 pour permettre les transmissions de données par radio entre les îles. Bien que ce réseau ne soit plus utilisé, ses concepts ont été repris par l'Ethernet. Histoire C'est Norman Abramson qui est à l'origine du projet. L'un des buts était de créer un réseau à faible coût d'exploitation pour permettre la réservation des chambres d'hôtels dispersés dans l'archipel d'Hawaï. Pour pallier l'absence de lignes de transmissions, l'idée fut d'utiliser les ondes radiofréquences. Au lieu d'attribuer une fréquence à chaque transmission comme on le faisait avec les technologies de l'époque, tout le monde utiliserait la même fréquence. Un seul support (l'éther) et une seule fréquence allaient donner des collisions entre paquets de données. Le but était de mettre au point des protocoles permettant de résoudre les collisions qui se comportent comme des perturbations analogues à des parasites. Les techniques de réémission permettent ainsi d'obtenir un réseau fiable sur un support qui ne l'est pas. APIPA APIPA (Automatic Private Internet Protocol Addressing) ou IPv4LL est un processus qui permet à un système d'exploitation de s'attribuer automatiquement une adresse IP, lorsque le serveur DHCP est hors service. APIPA utilise la plage d'adresses IP 169.254.0.0/16 (qu'on peut également noter 169.254.0.0/255.255.0.0), c'est-à-dire la plage dont les adresses vont de 169.254.0.0 à 169.254.255.255. -

Ela define cabeamento e sinais elétricos para a camada física, e formato de pacotes e protocolos para a subcamada de controle de acesso ao meio (Media Access Control - MAC) do modelo OSI.1 A Ethernet foi padronizada pelo IEEE como 802.3.
