摘要： In one embodiment, a device receives a destination unreachable message originated by a particular node along a first source route, the message carrying an encapsulated packet as received by the particular node. In response, the device may determine a failed link along the first source route based on a tunnel header and the particular node. Once determining an alternate source route without the failed link, the device may re-encapsulate and re-transmit the original packet on an alternate source route with a new tunnel header indicating the alternate source route (e.g., and a new hop limit count for the tunnel header and an adjusted hop limit count in the original packet).

摘要： In one embodiment, a node may determine a trigger for establishing transmission priority on a path through a shared-media communication network for priority traffic to a particular node. As such, the node may generate a path clear message (PCM) that would instruct one or more receiving nodes along the path to suspend transmission for traffic other than the priority traffic for a specified duration, and also to transmit a local non-repeated distributed message to one or more neighbor nodes of each respective receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration. After transmitting the PCM along the path to the particular node to establish the transmission priority for the priority traffic along the path through the shared-media network, the priority traffic may be transmitted to the particular node along the path during the transmission priority.

摘要： A segment within a virtual network is identified as being supported by a segment bundling device. The segment within the virtual network supports a first host connected to a first bridging device and a second host connected to a second bridging device. The segment bundling device is used to receive virtual network address information describing the virtual network segmentation identifier (ID) for the segment used for receiving virtual network traffic for the first and second host. A segment bundling table associating a bundle ID with the virtual network segmentation identifier based on the upper ID and the lower ID of the virtual network ID is generated by the segment bundling device. The segment bundling device is used to distribute the segment bundling table to traffic forwarding devices in the virtual network that interface with the first bridging device and the second bridging device.

摘要： 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.

摘要： In one embodiment, a device in a computer network monitors an alternating-current (AC) waveform of an electrical power source at the device, where the power source is part of a polyphase power source system. Once the device determines a particular phase of the polyphase power source system at the device, then the device joins a directed acyclic graph (DAG) specific to the particular phase. In another embodiment, a device detects a time of a zero crossing of the AC waveform, and may then determine a particular phase of the polyphase power source system at the device based on the time of the zero crossing relative to a corresponding location within a frequency hopping superframe of the computer network.

摘要： In one embodiment, certain nodes in a computer network maintain a plurality of routing topologies, each associated with a different corresponding delay (e.g., dynamically adjusted). Upon receiving a packet with an indicated delay budget at a particular node, the node updates the delay budget based on an incurred delay up to and including the particular node since the indicated delay budget was last updated, and selects a particular routing topology on which to forward the packet based on the updated delay budget and the corresponding routing topology delays. The packet may then be forwarded with the updated delay budget on the selected routing topology, accordingly.

摘要： Efficiency of silicon photovoltaic solar cells is increased by an annealing process for immobilizing oxygen formed in Czochralski-grown silicon. The annealing process includes a short anneal in a rapid thermal annealing chamber at a high temperature, for example, greater than 1150° C. in an oxygen-containing ambient. More preferably, the wafer is rapidly cooled to less than 950° C. without an intermediate temperature hold, at which temperature oxygen does not nucleate and/or precipitate. Subsequent processing to form a photovoltaic structure is typically performed at relatively low temperatures of less than 1000° C. or even 875° C.

摘要： In one embodiment, a switch in a computer network may receive a neighbor solicitation (NS) message for a target node for which no neighbor authentication (NA) reply has been received at the switch. The switch may then determine whether to forward the NS message to only non-constrained links of the switch, or to both non-constrained links and constrained links of the switch. The determining may be configured to intermittently result in forwarding the NS message for the target node to both the non-constrained links and the constrained links. The switch may then forward the NS message according to the determination.

摘要： In one embodiment, a node in a computer network joins a global ring associated with a distributed hash table (DHT), and maintains a DHT routing table and DHT database for the global ring. In addition, the node may determine a particular service class for which the node is configured, and may join a particular service-based sub-ring according to the particular service class, where all nodes of the particular service-based sub-ring are within the global ring. As such, a service-based DHT routing table and service-based DHT database may be maintained for the particular service-based sub-ring, such that DHT operations identified by the particular service class are routed to the particular service-based sub-ring (e.g., by a portal node).
