Abstract

Objectives: The main objective of this report is to describe in detail about the elements  of  Ubiquitous  Ethernet, Physical layers specifications of 40/100 Gbps Ethernet technology, various fields of applications and the evolution of   the predominant Ethernet from 100 Mbps to 1 Tbps data rate. Statistical Analysis: The Journey of the Ethernet from  the beginning of mid 1970’s is illustrated. The Physical layer specifications of latest 802.3ba Ethernet technology along with survey of the fields of applications made this report unique. Brief illustration of each application with its inherent protocol and the encoding /decoding of data communication over the serial lanes of the physical layer convey the core process of Ethernet technology. Findings: The Ease of adoptability made the remarkable Ethernet and its existence in variety fields of applications such as industry to avionics, video and voice based applications which are intended for higher network speeds. Such high data transfer applications are realized on far-flung networks by targeting the physical layer interfaces which are discussed elaborately. Up to date research findings and latest Amendments of IEEE 802.2bs which is meant for the data rate 400Gbps are cited in this report. Applications/Improvements: Broad literature survey of the existing IEEE 802.3 in various fields of application made this report unique, usher and Endeavour the researcher  in the field of data communications.
