    Abstract: Each mobile router in an ad hoc mobile network is configured for concurrently attaching to multiple parents advertising respective parent depths relative to a clusterhead of the ad hoc mobile network. The mobile router selects an advertised depth relative to the clusterhead based on adding a prescribed increment to a maximum one of the parent depths, enabling the mobile routers to form a directed acyclic graph relative to the clusterhead. Each mobile router sends to each of its parents a neighbor advertisement message specifying at least one reachable prefix, a corresponding cost for reaching the reachable prefix, and a corresponding sequence identifier that enables the parents to validate the neighbor advertisement message relative to stored router entries . Hence, mobile routers automatically can form a directed acylic graph relative to the clusterhead, and can distribute routing information with minimal overhead.

    Abstract: Mobile routers in a tree-based network topology with a single clusterhead in an ad hoc network establish connectivity based on each attached mobile router sending a neighbor advertisement message to an attachment mobile router via a corresponding egress interface. Any neighbor advertisement message received by a mobile router is used to identify specified network prefixes that are reachable via the source of the neighbor advertisement message. Each attached mobile router outputs to its attachment router another neighbor advertisement message that specifies the network prefix used by the mobile router, and the specified network prefixes from its attached mobile routers. The mobile router also identifies peer mobile routers having the same depth, and selectively shares limited routing information with the peer routers, enabling the mobile router to bypass the clusterhead and reach remote prefixes via the peer routers without burdening the tree.

    Abstract: In one embodiment, a root device may request that one or more devices of a computer network build a directed acyclic graph (DAG) for routing traffic within the computer network based on an objective function (OF), where the OF has one or more metrics to optimize the DAG against and optionally certain constraints. Particular devices that receive the request may then build the DAG based on the OF, and may determine and report OF feedback to the root device. Upon receiving the reports regarding OF feedback, the root device may then adjust the OF based on the feedback, and request a rebuild of the DAG from the devices based on the adjusted OF.

    Abstract: In one embodiment, a method includes generating by a mobile router a home test message that includes a prefix option field specifying at least one mobile network prefix claimed to be owned by the mobile router. The method also includes outputting the home test message by the mobile router to a correspondent node via a prescribed home agent assigned to the mobile router, for initiation of a reverse routability test between the mobile router and the correspondent node that verifies the mobile router owns the at least one mobile network prefix. In another embodiment, the home agent is configured for forwarding a route optimization message, for example the home test message, to the correspondent node if the home agent determines that the at least one mobile network prefix is owned by the mobile router.

    Abstract: Gateways providing connectivity for respective private IPv4 networks to an IPv6 network establish communications between IPv4 nodes in the private network. Network address translation-protocol translation (NAT-PT) state entries are created by gateway pairs enabling translation of IPv4 packets between first and second IPv4 nodes in respective first and second IPv4 private networks into IPv6 packets for transmission via the IPv6 network. Each NAT-PT state entry specifies the IPv6 addresses for the first and second IPv4 nodes, and the IPv4 addresses used to identify the first and second IPv4 nodes in the corresponding private IPv4 network. Each gateway is configured for generating the IPv6 address for each local IPv4 node based on prepending its corresponding assigned private IPv4 address with a corresponding prescribed IPv6 prefix assigned to the gateway. Hence, gateways can dynamically establish communications between private networks without tunneling protocols, enabling deployment of latency-sensitive applications such as Voice over IP.

    Abstract: An access router of a local mobile network includes a delegation resource for delegating address prefixes and a routing resource configured for parsing reverse routing headers from received data packets. The delegation resource supplies each mobile router attaching to the local mobile network with a corresponding unique delegated address prefix within an available network prefix for use within the local mobile network. Each mobile router attached to the access router via another mobile router utilizes a reverse routing header to establish a tunnel with the access router, enabling the access router to source route messages to the mobile router via its corresponding local care-of address and next-hop addresses specified in the reverse routing header. Each mobile router creates a remote care-of address based on the delegated address prefix, minimizing the need for binding updates with the corresponding home agent as the mobile router moves within the local mobile network.
