Halt, stop, ich nehme alles zurueck und behaupte das Gegenteil!

NWay is a telecommunications protocol used with Ethernet networking devices (such as router and switch) to automatically negotiate the highest possible common transmission speed between two devices. The NWay protocol (also known as auto-negotiation or auto-sensing) was developed by National Semiconductor in 1994 in response to the networking industry's need for a mechanism to handle the connections between devices with varying connection speeds.

In an Ethernet network, a device may have the capability to operate at different speeds. NWay currently supports at least the following technologies:10BASE-T, 10BASE-T duplex, 100BASE-T, 100BASE-TX Full Duplex, and 100BASE-T4.
