Abstract
A network apparatus for a wide area network (WAN) includes a plurality of ports through which a local area network (LAN) and the WAN are connected; an active-port selecting unit that selects an active port from among the ports, and identifies a port other than the active port as a standby port; and a notifying unit that notifies an interface device for the LAN via the standby port that a line connected to the standby port is in a standby mode.
Claims11
A network apparatus for a wide area network (WAN), comprising:
- a plurality of ports through which a local area network (LAN) and the WAN are connected;
- an active-port selecting unit that selects an active port from among the ports, and identifies a port other than the active port as a standby port;
- and
- a notifying unit that notifies an interface device for the LAN via the standby port that a line connected to the standby port is in a standby mode.
A redundant network method for connecting a local area network (LAN) and a wide area network (WAN) through a plurality of ports, the method comprising:
- selecting an active port from among the ports;
- identifying a port other than the active port as a standby port;
- and
- notifying an interface device for the LAN via the standby port that a line connected to the standby port is in a standby mode.
A computer-readable recording medium that stores therein a computer program for connecting a local area network (LAN) and a wide area network (WAN) through a plurality of ports of an interface device for the WAN, the computer program causing a controller of the interface device to execute:
- selecting an active port from among the ports;
- identifying a port other than the active port as a standby port;
- and
- notifying an interface device for the LAN via the standby port that a line connected to the standby port is in a standby mode.
