摘要： Mobile routers (12) in a tree-based network topology with a single clusterhead (12a) in an ad hoc network (10) establish connectivity based on each attached mobile router sending a neighbor advertisement message (16) to an attachment mobile router via a corresponding egress interface. Any neighbor advertisement message (16) 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 (18) 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： Mobile routers establish a tree-based network topology in an ad hoc mobile network, the tree-based network topology having a single clusterhead and attached mobile routers. Each attached mobile router has a default egress interface configured for sending messages toward the clusterhead, and ingress interfaces configured for receiving messages from attached network nodes that are away from the clusterhead. A neighbor advertisement message received from an ingress interface away from a clusterhead is used by the attached mobile router to identify specified network prefixes that are reachable via the source of the neighbor advertisement message. The attached mobile router outputs on its default upstream interface a second neighbor advertisement message that specifies the network prefix used by the attached mobile router, and the specified network prefixes from the neighbor advertisement message received on the ingress interface. Hence, connectivity is established with minimal routing overhead.

摘要： A source IPv6 mobile node is configured for forwarding an IPv6 packet via an IPv4 connection with a destination IPv6 router. The IPv4 packet includes IPv4 source and destination addresses, a UDP source port and UDP destination port, and a synthetic tag address in the IPv6 destination address field. The synthetic tag address, a valid (routable) IPv6 care of address, has an address prefix routed to the IPv6 router. The address prefix specifies a forwarding protocol, the IPv4 destination address for the IPv6 router, and a site-level aggregation identifier. An address suffix for the synthetic tag address specifies the IPv4 source address, the UDP source port and UDP destination port. Hence, the synthetic tag address enables the destination IPv6 router to send an IPv6 reply packet back to the source IPv6 mobile node via the IPv4 network.

摘要： In one embodiment, a node "N" within a computer network utilizing directed acyclic graph (DAG) routing selects a parent node "P" within the DAG, and, where P is not a DAG root, may determine a grandparent node "GP" as a parent node to the parent node P. The node N may then also select an alternate parent node "P'" that has connectivity to GP and N. N may then inform P and P' about prefixes reachable via N, and also about P' as an alternate parent node to P to reach the prefixes reachable via N. Also, in one embodiment, P may be configured to inform GP about the prefixes reachable via N and also about P' as an alternate parent node to P to reach the prefixes reachable via N, and P' may be configured to store the prefixes reachable via N without informing other nodes about those prefixes.

摘要： 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.

摘要： 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.

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 (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.
