Abstract: Each mobile ad hoc node has an assigned hierarchy position within an identified tree-based aggregation group. Each ad hoc node is configured for selectively attaching to one of a plurality of available ad hoc nodes based on identifying a best match, for the assigned hierarchy position within the identified aggregation group, from among identifiable hierarchy positions of identifiable aggregation groups. Each ad hoc node also is configured for selectively attaching to any available ad hoc node based on a determined absence of any available ad hoc node advertising the identified aggregation group of the ad hoc node, or an aggregation group containing the identified aggregation group. Hence, a root node of an aggregation group can filter group-specific routing information from packets destined toward a network clusterhead, resulting in a scalable routing protocol that is not adversely affected by added nodes.

Abstract: An IPv4 node is able to send an IPv4 packet to an IPv4 destination via an IPv6 access network, based on translation of the IPv4 packet into an IPv6 packet for transmission via the IPv6 access network. The IPv4 packe is translated into the IPv6 packet by a local gateway. The IPv6 packet has an IPv6 source address that includes a prescribed address prefix assigned to the local gateway, and an IPv4 address of the IPv4 node. The IPv6 packet also includes an IPv6 destination address that includes a second a address prefix assigned to a remote gateway, and a second IPv4 adress of the IPv4 destination. The IPv6 packet is converted by the remote gateway into an IPv4 packet for reception by the IPv4 destination via an IPv4 network.

Abstract: A mobile router and a correspondent router, each configured for routing services for nodes within their routing prefixes associated with their respective routing tables, establish a secure, bidirectional tunnel based on a messaging protocol between each other and a route server resource. A reactive (i.e., on-demand) protocol is used that enables the requesting device (e.g., the mobile router, correspondent router), to obtain routing information in a secure manner from the route server. The mobile router sends a query via its home agent to the route server resource to identify the correspondent router serving the correspondent node. The mobile router sends a binding update request, specifying a home address and care-of address for the mobile router, to the correspondent router for establishment of a bidirectional tunnel. The correspondent router establishes the bidirectional tunnel, and updates its routing tables based on information from the route server resource.

Abstract: A router is configured for sharing routing rules with other routers, the routing rules defining aggregated routes according to a prescribed topology. Each routing rule used by the router for routing a packet having a corresponding matching destination address prefix (116), specifies a corresponding address prefix pattern rule for extracting an identified pattern from a portion of the destination address (120), and a gateway address pattern rule for generating a gateway address, for a gateway providing reachability to the destination address (122), based on applying the identified pattern to a specified pattern of the gateway address. The router generates a routing update message that describes the address prefix pattern rule and the gateway address pattern rule, and outputs the routing update message to a second router (126) according to a prescribed distance vector routing protocol.

Abstract: A router (e.g., a home agent for an IPv6 mobile router) is configured for determining a destination router (e.g., the IPv6 mobile router) for a received packet based on accessing a routing table having multiple routing entries, each routing entry including a routing key and a routing field that specifies one of a prescribed address specifying the destination router and a computation tag. The computation tag specifies a prescribed function to be executed to calculate a determined address for the destination router (e.g., the home address for the lPv6 mobile router). The router identifies, for each received packet, the matching routing entry based on the corresponding routing key, and in response to detecting the computation tag in the routing field, selectively executes the corresponding function to calculate the determined address for the destination router.

Abstract: A source IPv6 mobile router is configured for establishing an IPv4 tunnel with destination IPv6 mobile router using a synthetic tag address, specifying a forwarding protocol, and IPv4 source and destination addresses. If an optional transport header is used (e.g, UDP port), the source port and destination port also are added to the synthetic tag address. The IPv6 packet includes a reverse routing header that enables the destination IPv6 mobile router to recover routing information for reaching the source IPv6 mobile router via the IPv4 network. Hence, all IPv4 routing information that may be needed by the destination IPv6 mobile router in sending an IPv6 reply packet back to the source IPv6 mobile router is maintained in the routing header specified in the IPv6 reply packet.

Abstract: A mobile router is configured for optimized utilization of reverse routing headers, to specify a path between an originating mobile router and a home agent. Reverse routing headers enable each mobile router within the path to the home agent to specify its care of address, enabling the home agent to establish a bidirectional tunnel to the originating mobile router via the corresponding mobile router. The mobile router selectively updates the reverse routing header in a received packet by inserting the source address value of the received packet into the reverse routing header and inserting its corresponding care of address into the specifies reachability of a most recent entry in the reverse routing header via the source address value. The mobile router also may request the originating mobile router to increase the reverse header size.

Abstract: Methods and apparatus for processing registration requests by a Home Agent supporting Mobile IP are disclosed. A registration request is received from each of a plurality of Mobile Nodes, the registration request specifying a care-of address. A binding is established between each of the plurality of Mobile Nodes and the associated care-of address, each of the plurality of Mobile Nodes being associated with one another. For instance, the plurality of Mobile Nodes may be statically or dynamically assigned the same Home Address. A tunnel is then created between the Home Agent and the care-of address for each of the plurality of Mobile Nodes, thereby enabling a server request to be distributed by the Home Agent to one of the plurality of Mobile Nodes via the associated tunnel. For instance, a server request addressed to the Home Address may be forwarded to one of the Mobile Nodes assigned that Home Address.
