Abstract:
An acquisition unit (15a) acquires a packet passing through an active system path and a packet passing through a standby system path. An aggregation unit (15b) aggregates, using an acquired packet, information relating to the acquired packet. An assessment unit (15c) compares information relating to the aggregated packets between the active system and standby system paths and assesses whether there is a difference in state information that represents an operation state in an NF. When it has been assessed that there is a difference, an indication unit (15d) indicates to the NF of the active system path and the NF of the standby system path facing the NF of the active system path that the state information is to be synchronized.
