A network traffic monitoring system includes a router, a terminal adaptor, a digital service unit, a frame relay/leased network, a traffic monitoring apparatus, and a monitor. A subscriber line is connected to the router. The terminal adaptor interfaces the router to the network side. The digital service unit is connected to the terminal adaptor through an I interface. The frame relay/leased network is made up of at least one of a higher-speed relay router and a switching unit and transmission lines. The traffic monitoring apparatus monitors the internet traffic on a physical line between the terminal adaptor and the digital service unit. The monitor controls the traffic monitoring means to start and stop totalization processing, sets a subnet mask for determining a totalization unit, and acquires traffic information as a totalization result from the traffic monitoring apparatus.
