Abstract: In one embodiment, a network device determines a set of routes to one or more reachable addresses and also a set of no-routes to one or more non-reachable addresses in a computer network. The routes and no-routes may then be aggregated into one or more reachable route prefixes with one or more corresponding non-reachable no-route prefix exceptions. As such, the aggregated combination of route prefixes and no-route prefix exceptions may be utilized by the network device.

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 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.

Abstract: Methods and apparatus for registering with a Home Agent are disclosed. The network device sends a registration request having a home address field including an IP address to a Home Agent associated with the IP address. The registration request indicates one or more ports of the network device via which data packets or server requests addressed to the IP address are to be received. The ports may be specified in a port extension to the registration request. In addition, the registration request may indicate a priority to be associated with the registration. The Home Agent updates its mobility binding table with the IP address and care-of address, as well as other information specified in the registration request, such as port and/or priority information. The Home Agent then sends a registration reply to the network device. When the registration request is not sent directly by the network device (e.g., via a collocated care-of address), the Foreign Agent updates its visitor table upon receipt of the registration reply with the Home Agent address and IP address, as well as port and/or priority information. The registration reply is then sent to the network device. In this manner, multiple registrations for a single device or user may be established according to specified port(s), thereby enabling various applications and/or devices to be prioritized.

Abstract: 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.

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. The mobile router attaches to one of the routers in the ordered default router list having a higher priority, and upon attaching to the router advertisement originator as its attachment router, the mobile router transmits its own corresponding router advertisement message including a corresponding tree option field that specifies the attributes of the mobile router within the network topology model, enabling other routers to selectively connect and/or reconnect within the mobile network based on their respective identified preferences.

Abstract: Optimal determination of wireless network pathway configurations may be provided. A computing device may receive an error profile and a response instruction associated with the error profile, as generated by a network controller. The computing device may then monitor, for an error, on a communication Track, in a network, between an ingress node and an egress node. Then, the computing device, upon detecting the error, can determine that the error is similar to the error profile, and based on the determination that the error is similar to the error profile, enact the response instruction. The response instruction can direct the computing device to switch from the communication Track to a communication sub Track between the ingress node and the egress node.

Abstract: Systems and methods may include sending, to a network registrar, an extended duplicate address request (EDAR) message including a first nonce generated by a host computing device, and receiving, from the network registrar, an extended duplicate address confirmation (ED AC) message including a second nonce, the second nonce being signed by the network registrar via a private key of a first public key infrastructure (PKI) key pair of the network registrar via a first signature. The method further includes sending a first neighbor advertisement (NA) message to the host computing device including the second nonce. The second nonce and the private key of the network registrar verifies the first signature from the network registrar, the verification of the first signature indicating that the router is not impersonating the network.

Abstract: In one embodiment, a device in a network sends Bidirectional Forwarding Detection (BFD) probes along a network tunnel associated with the device, to collect telemetry regarding the network tunnel. The device monitors an overhead associated with sending the BFD probes along the network tunnel. The device makes a determination that the overhead associated with sending the BFD probes along the network tunnel is unacceptable. The device switches, based on the determination, from sending BFD probes along the network tunnel to modifying data traffic sent via the network tunnel, to collect telemetry regarding the network tunnel.

Abstract: In one embodiment, a device in a network receives a notification from a neighbor of the device indicative of a child node of the device requesting a parent change from the device to the neighbor. The device updates an existing routing path from the device to the child node to be routed through the neighbor, in response to receiving the notification from the neighbor. The device receives an instruction to remove the updated routing path from the device to the child node through the neighbor. The device removes the updated routing path from the device to the child node, in response to receiving the instruction to remove the updated routing path.

Abstract: In one embodiment, a device in a network sends a first multicast message to a plurality of destinations in the network. The first multicast message includes a first bitmap that identifies the destinations. The device receives one or more acknowledgements from a subset of the destinations. The device determines a retransmission bitmap that identifies those of the plurality of destinations that did not acknowledge the first multicast message, based on the received one or more acknowledgements. The device sends a retransmission multicast message to those of the plurality of destinations that did not acknowledge the first multicast message. The retransmission multicast message includes the retransmission bitmap.
