Claim:
A method of allowing a universal plug and play (UPnP) device to provide a Quality of Service (QoS) manager service, the method comprising: receiving a QoS request based on a QoS mode from a control point, wherein the received QoS request comprises an identifier for representing the QoS mode from among a plurality of QoS modes; acquiring traffic policies that are previously set for a plurality of traffic items for the QoS mode from a QoS policy holder service, the QoS mode being among the plurality of QoS modes managed by a QoS policy holder; and controlling a plurality of QoS device services of the network based on the acquired traffic polices, wherein a first priority for a traffic item is acquired in response to the identifier representing a first QoS mode of the plurality of QoS modes, and a second priority, different from the first priority, for the traffic item is acquired in response to the identifier representing a second QoS mode of the plurality of QoS modes, and wherein each of the plurality of QoS modes corresponds to a plurality of traffic policies for the plurality of traffic items.
