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). The DCA node device then processes context information received from the ad hoc wireless network (step). 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). The DCA node device then performs a trust bridge deployment to enable the second node device to serve as the new trust bridge (step).

Disclosed is a method for aggregating parallel data links connecting two end-point devices into a logical link. If one of the parallel data links is a multi-point link, then an end-point device can still access that link to route traffic to an end station on the link (that is, to a device other than the other end-point device of the logical data link). In the terminology of this disclosure, the logical aggregated link is accessed through an 'aggregated port' on an end-point device, while the constituent multi-point link is accessed directly through a 'singleton port.' By assigning a smaller cost to the aggregated port than to the singleton port, embodiments avoid creating routing loops. In some embodiments, the aggregation is performed at Layer 2 of the Open System Interconnection seven-layer protocol model. Then, the methods of the present invention work well with existing IEEE 802.1 bridging architectures and protocols.

An apparatus, method and system for delivering Internet Protocol (IP) content within a system that includes a bypass architecture, using a Session Encapsulation Information Database (SEIDB). Within an existing PacketCable Multimedia (PCMM) framework used as a control plane for IP content bypass flow setup, the SEIDB system stores session bypass encapsulation information for IP content bypass flows within the system. Within the SEIDB, each entry of bypass encapsulation information has a flow classifier component that uniquely identifies a bypass flow in a manner that allows both a cable modem termination system (CMTS) and the IP content source to uniquely identify the bypass flow at the SEIDB. Initially, the CMTS gathers bypass encapsulation information and uploads it to the SEIDB. Before the bypass flow begins, the IP content source obtains the necessary bypass encapsulation information from the SEIDB, e.g., using a flow classifier as a search filter item.
