  • Alternate path FDDI standard LAN
    Patent number: 5317569
    Abstract: A local area network uses standard ANSI FDDI LAN concentrator stations and a first set of mutually reverse-direction data buses or loops, in conjunction with an additional set of mutually reverse-direction data paths. The standard FDDI protocols when applied in the context of the particular connections of the concentrator station operate in the event of a break in the data path terminating at an input or output port, to reconfigure the station to interconnect the buses in a manner which routes data around even multiple breaks in the buses, to thereby maintain communication integrity.
