Wired LAN: Ethernet
ETHERNET PROTOCOL
-
The IEEE has subdivided the data-link layer into two sublayers: logical link control (LLC) and media access control (MAC)

-
Ethernet Evolution
-
Has gone through four generations: Standard Ethernet (10 Mbps), Fast Ethernet (100 Mbps), Gigabit Ethernet (1 Gbps), and 10 Gigabit Ethernet (10 Gbps).
GIGABIT ETHERNET
The need for an even higher data rate resulted in the design of the Gigabit Ethernet Protocol (1000 Mbps).
-
Goals of the Gigabit Ethernet were to upgrade the data rate to 1 Gbps, but keep the address length, the frame format, and the maximum and minimum frame length the same.
STANDARD ETHERNET
-
Addressing
Each station on an Ethernet network (such as a PC, workstation, or printer) has its own network interface card (NIC).
-
The Ethernet address is 6 bytes (48 bits), normally written in hexadecimal notation, with a colon between the bytes.
10 GIGABIT ETHERNET
The idea is to extend the technology, the data rate, and the coverage distance so that the Ethernet can be used as LAN and MAN (metropolitan area network).
The IEEE committee created 10 Gigabit Ethernet and called it Standard 802.3ae. This data rate is possible only with fiber-optic technology at this time.
