Document Type and Number:
Japanese Patent JP7435759
Kind Code:
B2
Abstract:
Provided are a failure detection system, a failure recovery system, a failure detection method, and a non-transitory computer readable medium that are capable of more easily estimating a degradation location of QoE. A failure detection system (10) is provided with a log collection unit (12) that collects a communication log including communication quality information from a relay device that terminates TCP communication, and a degradation estimation unit (16) that estimates, by using the communication quality information of the collected communication log, a degradation point indicating a point where a communication quality degradation factor exists in a communication path passing through the relay device.
