Chronologie vývoje Ethernetu

A musím si to sem dát ... jinak to nejde
Velmi zajimavý přehled - chronologie vývoje Ethernetu.

A Chronology of Ethernet

1972 - Ethernet used at Xerox PARC
1980 - Consortium of DEC, Intel and Xerox announced the Blue Book
1982 - Version 2 of the Blue Book issued.
1982 - ISOC RFC 826 definition of the address resolution protocol for Ethernet
1984 - ISOC RFC 894 definition of IP network using Ethernet links
1985 - IEEE 802.3 (slightly incompatible with v2)
1988 - IEEE published a collection of supplements.
1988 - ISOC RFC 1042 definition of IP network using IEEE 802.3/LLC links.
1989 - ISO 802.3a Ethernet for thin coaxial cable (10Base2).
1990 - IEEE 802.3i Ethernet over CAT-5 Unshielded Twisted Pair (10BaseT).
1990 - IEEE 802.1D Ethernet Bridging.
1993 - 10BT Hubs and Bridges have become a common component in LANs, and start replacing 10Base2/10Base5.
1993 - IEEE 802.3j defines Ethernet over Fibre (10BaseF).
1993- IEEE 802.1D MAC Layer Bridges (ISO 10038).
1995 - IEEE 802.3u defines Fast Ethernet (100BaseTX, 100BaseT4, 100BaseFX).
1998 - 100BT Fast Ethernet has become a common component in LANs (100BaseT4 was not widely adopted).
1998 - Full-duplex mode supported in Fast Ethernet.
1998 - IEEE 802.3z defines Gigabit Ethernet over Fibre (some years later in 802.3 ab over UTP).

2001 - IEEE 802.11 (wireless) and Gigabit Ethernet have become common LAN components.
2005 - IEEE 802.3ah Link-Layer OAM
2006 - 10 Gbps Ethernet over Category-6 (10000BT) UTP is available in commercial products.
2009 - Power over Ethernet (PoE)
2009 - 40 Gbps Ethernet (extendable to 100 Gbps) IEEE P802.3ba
