    Abstract: In one embodiment, an ingress device of a first routing domain in a computer network buffers received packets, and in response to receiving a request from a particular node indicating that the particular node has migrated from the first routing domain to a second routing domain, determines how to reach the particular node in the second routing domain, and forwards the buffered received packets to the particular node in the second routing domain, accordingly. In another embodiment, a device in the first routing domain migrates from the first routing domain to a second routing domain, and determines its new IP address. The device may then send a request to the first ingress router to forward buffered packets for the device to the second routing domain at the new IP address, and may thus receive buffered packets forwarded from the first ingress router at the device in the second routing domain.

    Abstract: In one embodiment, a particular field area router (FAR), in a local computer network (e.g., a mesh network) having a plurality of FARs, advertises a common subnet prefix assigned to the local computer network into a global computer network. Each of the plurality of FARs of the local computer network is configured to accept any traffic destined to the local computer network, and a tunnel overlay is built among the plurality of FARs. Upon receiving a packet at the particular FAR destined to a particular device in the local computer network, and in response to the particular FAR not having a host route to the particular device, it forwards the packet on the tunnel overlay to another of the plurality of FARs of the local computer network.

    CPC classification number: G06N99/005

    Abstract: In one embodiment, a node receives a request to initiate a shadow joining operation to shadow join a field area router (FAR) of a computer network, and preserves its data structures and soft states. The shadow joining operation may then be initiated to shadow join the FAR, wherein shadow joining comprises preforming join operations without leaving a currently joined-FAR, and the node measures one or more joining metrics of the shadow joining operation, and reports them accordingly. In another embodiment, a FAR (or other management device) determines a set of nodes to participate in a shadow joining operation, and informs the set of nodes of the shadow joining operation to shadow join the FAR. The device (e.g., FAR) participates in the shadow joining operation, and receives reports of one or more joining metrics of the shadow joining operation measured by the set of nodes.

    Abstract: In one embodiment, a management device receives one or more fate-sharing reports locally generated by one or more corresponding reporting nodes in a shared-media communication network, the fate-sharing reports indicating a degree of localized fate-sharing between one or more pairs of nodes local to the corresponding reporting nodes. The management device may then determine, globally from aggregating the fate-sharing reports, one or more fate-sharing groups indicating sets of nodes having a global degree of fate-sharing within the communication network. As such, the management device may then advertise the fate-sharing groups within the communication network, wherein nodes of the communication network are configured to select a plurality of next-hops that minimizes fate-sharing between the plurality of next-hops.

    Abstract: In one embodiment, a data packet message is provided which includes a routing header configured to accommodate both a deterministic source route and a probabilistic source route for encoding a nodal source route. The nodal source route is selectively encoded with one or both of a deterministic source route and a probabilistic source route based upon one or more predetermined criteria.

    Abstract: In one embodiment, a sender in a shared-communication network determines whether a pending frame is low-latency or high-throughput, and sets a maximum transmission unit (MTU) of the pending frame as a first MTU in response to a low-latency frame and a longer second MTU in response to a high-throughput frame. In another embodiment, a receiver receives a data frame from a sender according to an MTU, and determines a trigger for adjusting the MTU based on latency requirements. In response to the trigger, the receiver sets an interrupt flag in a link-layer acknowledgment for the received data frame. In still another embodiment, a sender determines a pending low-latency data frame to send to a receiver operating according to an MTU, and sends a control message to the receiver to indicate the pending low-latency data frame and an adjusted MTU.

    Abstract: In one embodiment, a device in a network identifies a routing domain migration candidate node in a first routing domain that is in range of a second routing domain. The device determines that the second routing domain is able to accommodate the candidate node sending traffic via the second routing domain. The device determines that the candidate node should send traffic via the second routing domain, based in part on a determination that the second routing domain is able to accommodate the candidate node sending traffic via the second routing domain. The device causes the candidate node to send traffic via the second routing domain.
