Title:
NETWORK FAILURE DETECTION SYSTEM AND NETWORK FAILURE DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2014068283
Kind Code:
A
Abstract:
To provide a network failure detection system and a network failure detection device which can determine an appropriate RTT threshold in which propagation delay is considered.
A network failure detection device 100 groups monitoring target devices 200 having similar RTT values on the basis of an RTT of each monitoring target device 200 which is acquired at a usual (normal) time. The network failure detection device 100 generates distribution of the RTT value for each group and determines the RTT threshold of the group from the generated distribution of the RTT value.
