Abstract
A network analysis method using an information processing device includes receiving packets from a wired network; extracting, from a set of the received packets, a delay packet that was received after at least a predetermined period of time had elapsed since an immediately preceding packet was received; and determining that a packet delay because of a control signal wirelessly sent from an access point coupled to the wired network has occurred, based on periodicity of a timing at which the delay packet was received.
