Introduction to the 100VG-AnyLAN Technology

The 100VG-AnyLAN is a new network technology, currently being defined as the IEEE 802.12 standard, that provides a data rate of 100 Mbits per second on 4-pair, category 3 (voice grade), category 4, or category 5 unshielded twisted-pair (UTP) cable. Future implementations will also support 2-pair UTP, 2-pair shielded twisted-pair (STP), and fiber-optic cabling. The 100VG-AnyLAN technology supports all of the network design rules and topologies of 10Base-T Ethernet and token ring networks. These features allow organizations to leverage their existing network and cable infrastructures while upgrading to higher transmission speeds.

100VG-AnyLAN uses a centrally controlled access method referred to as Demand Priority. This access method is a simple, deterministic request method that maximizes network efficiency by eliminating network collisions and token rotation delays. In addition, the demand priority protocol uses two levels of priority for each user request to guarantee support for emerging time-critical multimedia applications such as real-time video and audio for video conferencing or interactive video.

100VG-AnyLAN also offers message-frame compatibility with 802.3 Ethernet and 802.5 token ring networks. Frame compatibility allows the user to transparently leverage existing network operating systems and user software applications when migrating to a 100VG-AnyLAN network. In addition, the frame type compatibility allows 100VG-AnyLAN to connect to existing Ethernet and token ring networks via a simple bridge. 100VG-AnyLAN may also be routed to FDDI and ATM backbones, and wide area network (WAN) connections.
