UPNP QOS NETWORK SYSTEM AND METHOD FOR BOOKING PATH AND RESOURCE

摘要

A UPnP(Universal Plug and Play) QoS(Quality of Service) network system and a path and resource reservation method thereof are provided to reserve correct network resources and offer a more stable QoS by reserving a network resource according to path information and resource reservation information so that a calculated path can be matched with a path reserved for network resources. A UPnP QoS network system comprises a plurality of UPnP QoS execution devices(210-230) and a UPnP QoS management device(100). Each of the UPnP QoS execution devices collects and provides network state information, reserves network resources according to path information and resource reservation information, and executes QoS for a requested service. The UPnP QoS management device acquires and provides path information and resource reservation information in consideration of the QoS class of a requested service and the network state information provided from an associated UPnP QoS execution device.
