IEE802.3af POWER OVER ETHERNET:A RADICAL NEW TECHNOLOGY



What s all this Power Over Ethernet Stuff Anyway?
Power Over Ethernet technology allows IP telephones, wireless LAN Access Points and
other appliances to receive power as well as data over existing LAN cabling, without
needing to modify the existing Ethernet infrastructure.
It has just become an international standard, called IEE802.3af, as an extension to the
existing Ethernet standards. The freezing of the standard w ....etc

Power Over Ethernet


PoE
Power over Ethernet is a mechanism for supplying power to network devices over the same cabling used to carry network traffic. PoE allows devices that require power, called Powered Devices (PDs),such as IP telephones, wireless LAN Access Points, and network cameras to receive power in addition to data, over existing infrastructure without needing to upgrade it.
This feature can simplify network installation and maintenance by using the switch as a central power source for other network ....etc

Power over Ethernet (PoE) is a revolutionary technology that extends the already ultra-broad functionality of Ethernet by supplying reliable DC power over the same twisted-pair cable that currently carries Ethernet data. PoE, modeled after the technology used by the telecommunications industry to supply reliable power to telephones, enables lifeline quality power for IP telephones (VoIP) as well as many other low power Ethernet network devices like wireless access points (WAP) and security cameras.
When locating access points, system designers ....etc

ppt for the iee paper the survey of ethernet lan security

Abstract

Ethernet is the survivor of the LAN wars. It is hard to find an IP packet that has not passed over an Ethernet segment. One important reason for this is Ethernet's simplicity and ease of configuration. However, Ethernet has always been known to be an insecure technology. Recent successful malware attacks and the move towards cloud computing in data centers demand that attention be paid to the security aspects of Ethernet. In this paper, we present known Ethernet related threat ....etc

Abstract:
Ethernet has become the communications interface of choice for devices deeper and deeper into the network. The vast majority of users of the global Internet and corporate intranets see the Ethernet jack as their interface to the outside word. The scope of Ethernet was originally restricted to 10 Mbps interfaces and connections within the same Local Area Network (LAN) but has since expanded to cover a wide range of rates and extend across the campus as well. More universal than any other communications interface, the Ethernet jack has ....etc
