IEEE 802.3-2012 - X GIGABIT ETHERNET

 

The Ethernet standard family, the IEEE 802.3, dates back to early 1980's. Nowadays, Ethernet is getting more use modes and new protocols to convey as high-speed network computing and 4G radio base station applications are adopting 10 GbE as their backhaul technology.

Systems communicating over Ethernet divide a stream of data into shorter pieces called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted.

As per the OSI model, Ethernet provides services up to and including the data link layer.

Unlike previous Ethernet standards, 10 gigabit Ethernet and above only define full duplex point-to-point links which are generally connected by network switches. Shared medium CSMA/CD has not been carried over from the previous generations of Ethernet standards. Half duplex operation and hubs do not exist in 10 GbE and above.

10+ gigabit Ethernet applications include, for example, high-performance network computing & storage modules, and 4G radio base stations. 

Visit the IEEE website, 802.3 section, for more details of the Ethernet standard.

New standards are coming up to enable Base Station fronhaul traffic through Ethernet.  IEEE Project 1904 is working on this (IEEE P1904.3 - Standard for Radio Over Ethernet Encapsulations and Mappings (https://standards.ieee.org/develop/project/1904.3.html))
