摘要： Each network node having at least one destination-oriented link toward a directed acyclic graph (DAG) destination can receive a corresponding set of path performance metrics via the destination-oriented link. The set of path performance metrics, initiated by the DAG destination outputting initial link metrics on each of its source-connecting links, identifies aggregate link metrics for a corresponding path to the DAG destination via the corresponding destination-oriented link. The network node outputs a corresponding updated set of path performance metrics on each of its source-connecting links based on the received set of path performance metrics and the corresponding link metric for the corresponding source-connecting link. Hence, each network node in the DAG can assess the performance of each connected path to the DAG destination, and forward a data packet via a selected destination-oriented link based on the corresponding path performance metrics and forwarding policies for the forwarded data packet.

摘要： Each router in a network is configured for executing a link state routing protocol based on outputting a corresponding first link state advertisement message describing a connected link of the router and that specifies a first dynamic routing metric identifying a first cost of the connected link, and a corresponding variation metric identifying a statistical variation of the dynamic routing metric. Each router also is configured for selectively outputting a corresponding second link state advertisement message describing the connected link and that specifies the corresponding variation metric and an updated dynamic routing metric identifying an updated cost of the connected link relative to the first cost, the second link state advertisement message selectively output based on the updated dynamic routing metric differing from the first dynamic routing metric by more than the variation metric, or the router having received another link state advertisement from another router in the network.

摘要： 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.

摘要： Each network node in a network is configured for calculating a directed acyclic graph that provides at least one path from all the other network nodes toward the one network node. The network node performs a modified shortest path first calculation by identifying next-hop nodes adjacent to the network node, and orienting the link of each next-hop node toward itself (i.e., the origin). The network node also identifies secondary adjacent nodes, adjacent to each of the next hop nodes, and extends paths from next-hop nodes to the associated secondary adjacent nodes while orienting each of the links of the path between adjacent nodes and next-hop nodes toward the next hop nodes. The paths of the nodes form a directed acyclic graph from any other network node toward the origin, enabling distribution of the directed acyclic graph to the other network nodes for optimized reachability to the network node.

摘要： 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 IPv6 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.

摘要： 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, specifies a corresponding address prefix pattern rule for extracting an identified pattern from a portion of the destination address, and a gateway address pattern rule for generating a gateway address, for a gateway providing reachability to the destination address, based on applying the identified pattern to a specified portion 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 according to a prescribed distance vector routing protocol (e.g., Multiprotocol Extension for Border Gateway Protocol).

摘要： A network includes network nodes and a gateway. Each network node has a corresponding unique in-site IPv6 address for communication within a prescribed site, each in-site IPv6 address having a first IPv6 address prefix that is not advertised outside of the prescribed site. Network nodes can obtain from within the prescribed site a unique extra-site IPv6 address for mobile or extra-site communications. The extra-site IPv6 address has a second IPv6 address prefix, distinct from the first IPv6 address prefix, advertised by the gateway to the prescribed site and the wide area network. The gateway establishes a secure connection (e.g., tunnel) with each corresponding IPv6 node using its corresponding extra-site IPv6 address, and creates a corresponding binding cache entry specifying the corresponding extra-site IPv6 address and in-site IPv6 address. Hence, the gateway provides wide area network access while maintaining secrecy of the in-site IPv6 addresses.
