Patent ID: 7751414

Claim:
A bridge for heterogeneous QoS networks comprising: a UPnP QoS processing unit for collecting connection information connected through the networks and QoS requirement information thereof through an UPnP (Universal Plug and Play) QoS (Quality of service) structure; a bridge function unit for establishing and releasing connection by allocating resources based on the collected connection information and QoS requirement information, and performing a bridging operation according to connection information of a received frame; at least two of network device drivers physically connected to the networks for receiving data from a corresponding network and transferring the received data to the bridge function unit, or transmitting data from the bridge function unit to a corresponding network; wherein the bridge function unit comprises: an adaptive QoS managing unit for transforming the collected connection information of application service and the QoS requirement information thereof to global information to be processed in the bridge, and controlling the bridge function unit to perform a bridging operation for a requested application service and a QoS thereof; a flow managing unit for storing connection information of each flow of application service established in each network and QoS information of a corresponding connection; a bridge QoS processing unit for managing resources of the bridge in response to the control of the adaptive QoS manager, allocating resources required for establishing a connection, obtaining QoS information corresponding to connection information of a received frame, and providing a QoS based on the QoS information; and at least two of network QoS processing unit for establishing a QoS of each network and monitoring a link state.
