摘要： Various embodiments disclosed herein enable performing energy detection on a subset of a channel. In various embodiments, a method of performing energy detection is performed by a computing device. In various embodiments, the computing device includes a wireless transceiver, one or more processors, and a non-transitory memory. In various embodiments, the method includes performing energy detection on one or more overlapping portions of a first channel and a second channel. In some embodiments, the method includes determining whether a detected energy level from the energy detection satisfies a threshold. In some embodiments, the method includes transmitting a signal into the first channel based on the threshold being satisfied.

摘要： Presented herein are techniques that aggregate messages using a subroot node. A plurality of messages is received from a corresponding plurality of nodes by a subroot node acting as a proxy in a wireless mesh sub-network. The plurality of messages is aggregated into a single message according to a template. The single message is wireless transmitted to a root node, wherein the root node has a wired connection to a network.

摘要： Disclosed are systems, methods, and computer-readable media for integrating deterministic packet transmissions scheduling of short range local area networks (e.g., 6TiSCH networks) with deterministic packet transmission scheduling for wireless networks such as LTE/4G/5G networks. In one aspect, a wireless communication network includes a plurality of first nodes configured to communicate using a first communication protocol; and a second node configured to communicate with the plurality of first nodes using the first communication protocol and configured to communicate with a third node using a second communication protocol, the second node being further configured to map corresponding transmission schedule of the first communication protocol to a second transmission schedule for the second communication protocol.

摘要： In one embodiment, a particular device along a path in a deterministic network receives a first packet sent from a source towards a destination via the path. The particular device sends the first packet to a next hop device along the path, according to a deterministic schedule associated with the first packet. The particular device determines, after sending the first packet, an action to be performed on the first packet. The particular device then sends a second packet to the next hop device indicative of the determined action. The second packet causes another device along the path to perform the action on the first packet.

摘要： In one embodiment, an elimination point device in a network obtains a master secret from a network controller. The elimination point device assesses, using the master secret, whether an incoming packet received by the elimination point device from a redundant path between the elimination point device and a replication point device in the network includes a valid message integrity check (MIC). The elimination point device determines whether the incoming packet was injected maliciously into the redundant path, based on the assessment of the incoming packet. The elimination point device initiates performance of a mitigation action in the network, when the elimination point device determines that the incoming packet was injected maliciously into the redundant path.

摘要： In one embodiment, a supervisory device in a network forms a virtual access point (VAP) for a node in the network. A plurality of access points (APs) in the network are mapped to the VAP as part of a VAP mapping and the node treats the APs in the VAP mapping as a single AP for purposes of communicating with the network. The supervisory device determines a traffic type of traffic associated with the node. The supervisory device assigns the node to a selected wireless channel based in part on the traffic type of the traffic associated with the node. The supervisory device controls the VAP to use the channel assigned to the node.

摘要： In one embodiment, a supervisory device for a software defined networking (SDN) fabric predicts a failure in the SDN fabric using a machine learning-based failure prediction model. The supervisory device identifies a plurality of traffic flows having associated leaves in the SDN fabric that would be affected by the predicted failure. The supervisory device selects a subset of the identified plurality of traffic flows and their associated leaves. The supervisory device disaggregates routes for the selected subset of traffic flows and their associated leaves, to avoid the predicted failure.

摘要： In one embodiment, a supervisory device in a network forms a virtual access point (VAP) for a node in the network. A set of access points (APs) in the network are mapped to the VAP as part of a VAP mapping and the node treats the APs in the VAP mapping as a single AP for purposes of communicating with the network. The supervisory device receives measurements from the APs in the VAP mapping regarding communications associated with the node. The supervisory device identifies a movement of the node based on the received measurements from the APs in the VAP mapping. The supervisory device adjusts the set of APs in the VAP mapping based on the identified movement of the node.

摘要： In one embodiment, a supervisory device in a network assigns different access points in the network to different access point groupings. Each of the different access point groupings uses a different network path to communicate with a given endpoint in the network. The supervisory device selects at least one of the access points in each of the different access point groupings for mapping to a virtual access point (VAP) for a node in the network as part of a VAP mapping. The supervisory device instructs the selected access points to form a VAP for the node. The node treats the access points in the VAP mapping as a single access point for purposes of communicating with the network.

摘要： In one embodiment, a supervisory device in a network forms a virtual access point (VAP) for a node in the network whereby a plurality of access points (APs) in the network are mapped to the VAP as part of a VAP mapping. The node treats the APs in the VAP mapping as a single AP for purposes of communicating with the network. The supervisory device determines a data traffic management strategy for the node based on traffic associated with the node. The supervisory device instructs the APs in the VAP mapping to implement the data traffic management strategy for the node.
