Digital Equipment, Intel, Xerox (Ethernet) (DIX)

In 1980, the companies Digital Equipment Corporation, Intel and Xerox (DIX) had called the results of a joint project on an Ethernet design Ethernet V1.0.

Compared to the experimental Ethernet, the transmission speed on the transmission medium was increased from 3 Mbit/s to 10 Mbit/s; the specification was completed and made more precise with the declared aim of achieving compatibility in heterogeneous networks with regard to the specified layers.

This specification was introduced to the Local Network Standards Committee of the IEEE and published essentially unchanged alongside the other standardization approaches in the first coherent status report of IEEE Project 802 as Draft B in October 1981. Almost simultaneously, the European Computer Manufacturers Association( ECMA) began its LAN standardization efforts. The DIX group also continued to work on completing the Ethernet specifications. As a result of the efforts to align version V1.0 with the IEEE drafts, the DIX Ethernet V2.0 specification was published in 1982.
