1. A method of monitoring processing of traffic performed by a session management function (SMF), the method comprising:
transmitting a measurement rule for a state of traffic processing to a user plane function (UPF); and
receiving information on the state of the traffic processing from the UPF in response to the transmitted measurement rule,
wherein
the measurement rule identifies a measurement place at which the state of the traffic processing is measured, information used to specify traffic that is a measurement target, and a technique for obtaining a time related to the state of the traffic processing,
the measurement place includes a port of a module performing a predetermined function provided in the UPF, and
the measurement rule includes first data when the time is determined based on data included in a header of the traffic that is the measurement target and includes second data that is different from the first data when the time is obtained from a clock.
