Abstract: A method for deploying a trust bridge in an ad hoc wireless network can provide interoperability for multi-organizational authentication. The method includes processing at a delegate certification authority (DCA) node device authorizations received from of a plurality of certification authorities (CAs) of different organizations, where the authorizations authorize the DCA node device to serve as a DCA representing the CAs (step 1105). The DCA node device then processes context information received from the ad hoc wireless network (step 1110). Next, the DCA node device determines, based on the context information, that a second node device should be enabled as a new trust bridge (step 1115). The DCA node device then performs a trust bridge deployment to enable the second node device to serve as the new trust bridge (step 1120).

Abstract: The method of the present invention provides efficient aggregation of link metrics for a subnetwork (102, 202, 302) in a communication network (100, 200, 300) having a plurality of interconnected subnetworks (102, 202, 302) that includes nodes (A, B, C, D) and links. Link metric values are summarized on a full-mesh topology (202) and encoded by a spanning tree topology (1004). The method encodes the link metric information contained in full-mesh topology with minimum compromise in the capability to recover it.

Abstract: An apparatus (1410) and method (300) for aggregating ATM virtual channels (1420) into virtual paths in order to gain bandwidth efficiency in the ATM network (1470). Virtual channels (1420) are aggregated into virtual paths (1430) according to ATM Service Category and further by ATM Traffic Descriptors (1440) and QoS Parameters (1450). An efficient set of QoS requirements (1450) for the virtual path are determined by the QoS requirements of the constituent virtual channels (1460).

Abstract: A method (800, 900, 1000) provides dynamic connection management in integrated communication networks such that an acceptable quality of service (QOS) over an entire duration of a connection is maintained. For example, the present invention facilitates adjustment of the QOS towards a requested level for a permanent voice call, holding a connection intact until a desired path is obtained. Where possible, a new path for the connection provides at least one agreed value that is renegotiated to a more desirable value without degrading the other agreed values.
