摘要： In one embodiment, a node determines an intention to transmit a diversely forwarded packet through a computer network, and as such, transmits a first version of the packet having a packet identifier (ID) and a first distinguisher value to a first next-hop node, and transmits a second version of the packet having the same packet ID and a second distinguisher value different from the first distinguisher value to a second next-hop node different from the first next-hop node. In another embodiment, a next-hop node that receives the packet determines whether any previously received packet at the next-hop node had a same packet ID and a different distinguisher value. In response to determining that no previously received packet has the same packet ID and different distinguisher value, the next-hop node stores the packet ID and the distinguisher value, and forwards the packet to a selected next-hop node.

摘要： In one embodiment, a centralized network management server (NMS) determines a network state of a low power and lossy network (LLN) based on resource utilization due to traffic in the LLN. The NMS also determines an admission state based on the network state, and admission control (network-wide and/or localized control) based on the admission state. As such, the centralized NMS can then administer the admission control for all nodes in the LLN, where network-wide control comprises a single control command to all nodes in the LLN, and the nodes direct admission based on the control command, and where localized control comprises a request-response exchange between the nodes and the centralized NMS, and the NMS directs admission on a per-request basis.

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 distributed intelligence agent (DIA), hosted on a border router that provides access for a computer network to a global computer network, determines a routing topology of the computer network, and also computes a traffic matrix for the computer network based on source and destination addresses of traffic traversing the DIA, the traffic matrix providing an estimate for an amount of traffic on each link of the routing topology. Accordingly, the DIA may determine one or more portions of the routing topology for which traffic engineering (TE) should be applied based on a threshold for traffic loads on the links, and may notify one or more nodes in the computer network to change its respective current next-hop in the routing topology to an alternate next-hop based on a TE solution computed by the DIA.

摘要： In one embodiment, each device in a frequency hopping communication network operates according to a common broadcast schedule for the network that simultaneously overlays a configured portion of all independently determined unicast listening schedules in the network, wherein the overlaid configured portion is based on broadcast schedule parameters consisting of a first time spent for broadcast transmissions in each broadcast period and a second time between broadcast periods. By monitoring network characteristics relating to unicast traffic and broadcast traffic in the network, updated broadcast schedule parameters may then be determined based on the network characteristics. Operation of the common broadcast schedule may thus be updated with the updated broadcast schedule parameters, accordingly.

摘要： In one embodiment, a source device detects a packet flow that meets criteria for multi-path forwarding, and forwards a probe packet on a primary path from the source device to a destination device, the probe packet carrying an indication to cause a plurality of transit devices along the primary path to add their respective local neighbor topology to the forwarded probe packet, and also to cause the destination device to compute a diverse path from the primary path based on the accumulated local neighbor topologies in the probe packet. Accordingly, the source device may receive a returned diverse path as computed by the destination device in response to the probe packet, and may thus forward the packet flow on the primary path and the diverse path from the source device to the destination device according to the multi-path forwarding.
