100VG-AnyLAN

100VG-AnyLAN

A 100 Mbps version of Ethernet developed by HP that was able to transport both Ethernet and Token Ring frames. It was a shared media LAN like Ethernet, but employed the Demand Priority access method rather than CSMA/CD, allowing real-time voice and video to be given high priority. For a while, 100VG-AnyLAN was also called "Fast Ethernet," but the IEEE 802.3u Fast Ethernet became the standard.

In 1993, the group and its companion 802.12 committee created a stir by each adopting a different LAN standard for operation at 100 Mb/s.
Meanwhile, the IEEE 802.12 working group expects to have a draft standard of the 1-Gb/s version of VG-AnyLAN by summer, with approval a year later.
To overcome the distance limitation over copper, the 802.12 group is considering a new physical layer for VG-AnyLAN and a 500-Mb/s operating speed, which would extend the range to 100 meters for Category 5 UTP wiring.
