We present a method of controlling the traffic of individual services by using an overlay network, which lets us flexibly add various functionalities. The overlay network provides control functionalities such as for constructing an overlay network topology for each service, calculating the optimal route for its quality of service (QoS), and caching content to reduce the amount of traffic. By applying traffic engineering taking into account each service's QoS requirements, this overlay network can overcome the problem of indiscriminate QoS degradation when the network becomes congested due to a sudden increase in traffic for a particular service.
