  • Method and apparatus for detecting the network link status of computer systems
    Patent number: 6215764
    Abstract: A method and apparatus for detecting the link status of a network device in a computer system. An automatic link status detection mechanism allows a system to operate intelligently in a normal operation mode if the link status is on, or a suspend mode if the link state is down. The mechanism includes an auto link poll controller and a polling cycle generator for generating a sequence of polling cycles to query the link status of the network device. A media independent interface management frame having a preamble field is generated in a polling cycle. Because of the improved preamble field, it is to assure that an exact polling cycle is complete when a polling cycle is issued to the physical layer of the network device.
