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 (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.

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.

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.
摘要翻译：源IPv6移动节点被配置为经由与目的地IPv6路由器的IPv4连接来转发IPv6分组。 IPv4分组包括IPv4源地址和目的地址，UDP源端口和UDP目的端口，以及IPv6目的地址字段中的合成标签地址。合成标签地址（一个有效的（可路由的）IPv6地址保护）具有路由到IPv6路由器的地址前缀。地址前缀指定转发协议，IPv6路由器的IPv4目的地址和站点级聚合标识符。合成标签地址的地址后缀指定IPv4源地址，UDP源端口和UDP目的端口。因此，合成标签地址使目的IPv6路由器能够通过IPv4网络将IPv6应答分组发送回源IPv6移动节点。

摘要： A gateway (12), configured for providing connectivity between a wide area network (14) and mobile routers (16) within a mobile ad hoc network (10), e.g. , MANET, is configured for registering the mobile routers with their respective home agents (18) using a prescribed mobile IP protocol, e.g. Mobile IPv6, (20). The gateway identifies the mobile routers using a prescribed proactive mobile ad hoc network routing protocol. The gateway locates, for each identified mobile router, its corresponding home agent via the wide area network according to the prescribed mobile IP protocol, and registers the corresponding identified mobile router with the home agent according to the prescribed mobile IP protcol. The gateway can then forward a packet received from a home agent to the corresponding mobile router. Hence, the gateway provides mobile routers within a mobile ad hoc network with access to the wide area network, without any necessity for the prescribed mobile IP protocol to be implemented within the mobile routers.

摘要： A wireless station having a wireless network device capable of providing a link-layer interface to a wireless network, a method operating at the link layer (L2) in the wireless station, and a carrier medium carrying computer readable code segments that when executed on a processor in the wireless station implement the method.

The method further includes gathering information about the received L2 frames, including L2 information and L3 information. The L3 information includes whether an AP is sending an IP packet from a mobility agent, such that the station may associate with a wireless network that is in communication with the mobility agent. The method further includes storing information about the wireless networks that the station can hear in a database. The information stored about each wireless network includes one or more of an identifier of the wireless network, the L3 information in the L2 frame received from the AP of the wireless network, a time stamp of when the L2 frame was received from the AP, and an indication of the signal strength of the L2 frame from the AP.

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 having a prescribed security relationship with the mobile router and correspondent router. 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, upon validating the home address is reachable via the care-of address, establishes the bidirectional tunnel, and updates its routing tables to specify that prescribed address prefixes are reachable via the mobile router home address.

摘要： A mobile router is configured for attaching to a selected router in a clustered network (e.g., a mobile ad hoc network) based on identifying a network topology model of the clustered network from received router advertisement messages that include tree information option fields specifying attributes of the network topology model. The mobile router selects which router advertisement originator to attach to based on correlating the attributes of the router advertisement originators relative to identified priorities, and orders the router advertisement originators within a default router list based on the identified priorities. If the mobile router detects a router from a second clustered network, the mobile router advertises to the attachment router that the second clustered network is reachable, enabling the two clustered networks to communicate using a point-to-point link between the respective attachment routers.
