Claims (8)

A device that is connected to at least one other device, forms a redundant device with the other device, and provides a virtual packet relay device that relays packets transmitted and received between information processing devices with the other device. There,
A calculation unit for calculating a failure rate indicating a probability of failure of the own device;
A device that becomes the master device among the devices that constitute the redundant device based on the failure rate of the own device calculated by the calculation unit and the failure rate of the other device notified by the control packet from the other device. An apparatus comprising: a switching destination apparatus selection unit for selecting.   The apparatus of claim 1, comprising:
  A packet transmitter for transmitting a control packet storing the failure rate of the own device to the other device
A device comprising:   An apparatus according to any one of claims 1 to 2,
  The switching destination device selection unit selects a device having the lowest failure rate as a master device from among slave devices configuring the redundant device.   An apparatus according to any one of claims 1 to 3,
  A monitoring processor that monitors the occurrence of monitoring information that is an event occurring in the device;
  A detection number storage unit that holds, for each piece of monitoring information, the number of times that the monitoring processing unit has detected the occurrence of the monitoring information; a failure rate of a device that constitutes the redundant device; or a number of detection times for each piece of monitoring information A processing unit that outputs or displays at least one of
  The said calculation part calculates the said failure rate based on the weighting value set with respect to the said monitoring information, and the frequency | count of detection for every said monitoring information. A device that is connected to at least one other device, forms a redundant device with the other device, and provides a virtual packet relay device that relays packets transmitted and received between information processing devices with the other device. There,
  A calculation unit for calculating a failure rate indicating a probability of failure of the own device;
  The priority of the own device is determined in consideration of the failure rate of the own device calculated by the calculation unit, and the failure rate of the other device notified by the control packet from the other device is determined in consideration of the determined priority. And a protocol processing unit that selects a master device from among the devices constituting the redundant device based on the priorities.   The apparatus of claim 5, comprising:
  An apparatus comprising: a packet transmission unit configured to transmit a control packet storing a priority in consideration of the failure rate of the own apparatus to the other apparatus. An apparatus according to any of claims 5 and 6,
  The protocol processing unit selects a device having the highest priority as a master device from among the devices constituting the redundant device.     An apparatus according to any one of claims 5 to 7,
  A monitoring processor that monitors the occurrence of monitoring information that is an event occurring in the device;
  A detection number storage unit that holds, for each monitoring information, a number of detections that is the number of times the monitoring processing unit has detected the occurrence of the monitoring information;
  A processing unit that outputs or displays at least one of the failure rate of the device itself or the number of times of detection for each monitoring information,
  The said calculation part calculates the said failure rate based on the weighting value set with respect to the said monitoring information, and the frequency | count of detection for every said monitoring information.
