Patent ID: 8135837

Claim:
A UPnP QoS (universal plug and play quality of service) network system comprising: a plurality of UPnP QoS execution devices configured to collect and provide network status information, and perform QoS for a requested service by reserving network resources on a selected path in response to path information and resource reservation information, the selected path being one selected among a plurality of paths; and at least one UPnP QoS management device configured to determine a path to be selected for the requested service by considering a QoS rank for the requested service and the network status information provided by the plurality of UPnP QoS execution devices, and provide the path information and the resource reservation information to the plurality of UPnP QoS execution devices, wherein the plurality of UPnP QoS execution devices select the path determined by UPnP QoS management and reserve network resources on the selected path in response to path information and resource reservation information provided by the UPnP QoS management device, wherein the path information is address information of all UPnP QoS execution devices located on a path from the device requesting the service to be provided to a target device, address information of neighboring devices of the UPnP QoS execution devices, or identification information of interface devices of the UPnP QoS execution devices.
