Inter-router adjustment method, router priority calculation device, and router device

An inter-router adjustment method comprising:

• an information request step of requesting router status information to all router devices belonging to a same sub-network;
• a step of acquiring the router status information and calculating priorities for deciding a router device that is to become an operating status based on the router status information so that the plurality of router devices can operate virtually as one router device;
• a step of transmitting the priorities calculated for the router devices respectively to the router devices;
• and
• a step for a first router device which received the priority to decide whether or not to become an operating status, depending upon the priority of its own and the priority of a second router device received from the second router device being in an operating status.

A router priority calculation device comprising:

• a router information gathering section for gathering router status information of router devices belonging to a same sub-network;
• a priority calculating section for calculating priorities deciding a router device that is to become an operating status based on the router status information so that a plurality of router devices can operate virtually as one router device;
• and
• a priority notifying section for notifying the priorities calculated for the router devices respectively to the router devices.

A router priority calculation device comprising:

• a router information gathering section for gathering router status information of the router devices belonging to a same sub-network;
• a priority calculating section for calculating priorities deciding a router device that is to become an operating status based on the router status information so that a plurality of router devices can operate virtually as one router device;
• a master deciding section for deciding a first router device that is to become an operating status and a second router device that is to be in a standby status, according to the priorities;
• and
• a master notifying section for notifying information identifying the decided router device to the router device.

A router device comprising:

• a status notifying section for forwarding router status information comprising at least any one of a line status, a process burden and a battery remaining capacity;
• a priority receiving section for receiving a priority deciding a router device that is to become an operating status so that a plurality of router devices belonging to a same sub-network can operate virtually as one router device;
• and
• a master deciding section for deciding whether to become an operating status or a standby status, according to the priority received and a priority notified from a first router device in an operating status.

A local network system comprising a router device that is comprised with

• a status notifying section for forwarding router status information comprising at least any one of a line status, a process burden and a battery remaining capacity;
• a priority receiving section for receiving a priority deciding a router device that is to become an operating status so that a plurality of router devices belonging to a same sub-network can operate virtually as one router device;
• and
• a master deciding section for deciding whether to become an operating status or a standby status, according to the priority received and a priority notified from a first router device in an operating status, and
• a router priority calculation device that is comprised with
• a router information gathering section for gathering router status information of router devices belonging to a same sub-network;
• a priority calculating section for calculating priorities deciding a router device that is to become an operating status based on the router status information so that a plurality of router devices can operate virtually as one router device;
• and
• a priority notifying section for notifying the priorities calculated for the router devices respectively to the router devices.
