Abstract: PURPOSE: An automatic high-speed failure recovery Ethernet multiplexing network system using a logic gate based switching chip is provided to select a port without additional device such as a processor or middleware. CONSTITUTION: A high-speed automatic failure recovery Ethernet multiplexing network system includes a port unit(100), a PHY chip unit(200), a MAC chip(300) and a switching unit(400). The port unit is connected to the outside. The PHY chip unit communicates a signal inputted and outputted through the port unit with a MII/GMII(Media Independent Interface/Gigabit Media Independent Interface) protocol. The MAC chip has a MAC address. The switching unit converts a port by switching a MMI/GMII signal. In case of failure in a port in an operation mode, the switching unit operates the port in a standby mode to an operating mode. A first MII/GMII signal inputted from a first port of the port unit and a second MII/GMII signal inputted from a second port are connected to a MII/GMII signal connected to the MAC chip.

Abstract: PURPOSE: A fault tolerant control ethernet device of a hybrid type and a fault tolerant control method thereof are provided to mix a software method changing a port by detecting a fault through a program. CONSTITUTION: A first and a second ports(110,120) input/output a signal of a LAN(Local Area Network) switch. A signal sensing unit(200) senses a signaling flow of an activated port interchanging data with the LAN switch between the first and the second ports. A switching control unit(300) changes the activated port according to data sensing of the signal sensing unit. The first and the second port are included in one network interface card(100).
