Abstract: A packet-switched data network is disclosed that includes a dynamic resource reservation adjustment module that adjusts unicast data flows in reserved resources of the data network to maintain an optimal level of QoS for an application session. A receiver node obtains a reservation for a plurality of unicast packet flows from various routers on the data network. The receiver node also makes a partial reservation for a predetermined amount of bandwidth on each respective router to compensate for one of the unicast packet flows if a respective router experiences a bottleneck.

Abstract: A method, system, and business model are disclosed for supporting handover between a mobile host and a corresponding node located in a heterogeneous network. Handover paths are established to accommodate a plurality of quality of service properties. Admission control is performed that considers the established handover paths and an established first reservation path. Gateways are contacted to determine a handover path to use. The determined handover path is used to support vertical handover. A second reservation path is established while maintaining the first reservation path and the handover path.
