IEEE 802.3-2012 Standard of Ethernet-networks

"IEEE 802.3 technologies and different networks on its their basis are everywhere, and the standard continues to develop", - David Law, the head of the working group of IEEE 802.3 of Ethernet Working Group and the outstanding engineer of HP Networking commented.

"When the Ethernet network was conceived in the 1970th years and for the first time in 1985 the IEEE 802.3 standard was published, his creators could not even imagine in what global transformational changes development will give them, - it continued. - The standard helped to construct new models a business vedniya, to open the new industries and to diversify life. This innovation cycle proceeds to this day".

"IEEE 802.3 is constantly updated to satisfy new requests. We see that the standard extends in horizontal direction - leaving in new segments, such as network distributing in cars, solutions for optimization of energy consumption, the solution for data processing centers and distribution of content. At the same time development happens and in vertical direction - speed increases, there are more various interfaces of connection", - the senior technical director of Broadcom Vel William of Dyab (Wael William Diab) who is a part of leadership team added.

IEEE 802.3 defines specifications of a physical layer (PHY) and a layer of access to network (MAC) in the home, corporate and city local area networks, explained in the standardizing body.

The new standard - IEEE 802.3-2012 - includes a set technical updates and improvements in comparison with the last audit of IEEE 802.3 which was carried out in 2008. Among features of the new standard: support of 10-gigabit Ethernet networks of Passive Optical Network (EPON) and reduced energy consumption. There were time synchronization and the improved support of applications in which increased requirements to integrity of data are imposed.

Also new standard included support of the speeds of 40 Gbps and 100 Gbps with preserving of compatibility with earlier set network IEEE 802.3 interfaces. For comparison, the IEEE 802.3-2008 standard offers the maximum speed of transfer dannykh10 to Gbps.
