  • Publication number: 20220329517
    Abstract: Embodiments relate to a routing information processing method and apparatus. The method implemented by a first network device includes: obtaining a local route corresponding to a second network device, where the local route includes a first identifier; allocating a first segment identifier based on the fact that the first identifier exists only in the local route; obtaining a local route and a remote route that correspond to a third network device, where each of the local route and the remote route includes a second identifier; allocating a second segment identifier based on the fact that the second identifier exists at least in the local route and the remote route; and sending routing information including the first segment identifier and the second segment identifier. This avoids traffic interruption of a failure-free single-homed network device in a scenario in which single-homing and multi-homing coexist.

  • Publication number: 20220289544
    Abstract: Provided is an optimization control method for stable operation of an aerial work platform. For an articulated boom type aerial work platform which does not overturn in three preset operational states, the maximum angle ?max of a folding boom angle ? is substituted into a known first stability control function L=g (?, ?, S) to obtain an optimized second stability control function L=f (?, S). The three preset operational states include: State I—a folding boom is fully extended at a maximum angle, and a main boom is fully retracted at a maximum angle; State II—the folding boom is fully retracted at a minimum angle, and the main boom is fully retracted at a maximum angle; and State III, the folding boom is fully retracted at a maximum angle, and the main boom is fully retracted horizontally.

  • Publication number: 20220294728
    Abstract: This application discloses a packet transmission path switching method. The method includes: After a first PE receives an Ethernet segment ES auto-discovery AD route sent by a second PE, the first PE establishes a bidirectional forwarding detection BFD session with the second PE based on the ES-AD route; based on the fact that the first PE determines that a status of the BFD session is a disconnected state, the first PE determines that a first link between the second PE and a first CE is faulty; and the first PE quickly switches a packet transmitted over a second link between the first PE and the second PE to a third link between the first PE and a third PE. This application implements fast and accurate switching of a packet transmission path.

  • Publication number: 20220247598
    Abstract: A packet detection method includes a first provider edge (PE) that sends a detection packet to a second PE, where the detection packet is used to enable the second PE to generate a response packet, and the detection packet includes a bypass virtual extensible local area network (VXLAN) tunnel source Internet Protocol (IP) address; the first PE receives, through a bypass VXLAN tunnel, a response packet for the detection packet, where the response packet includes the bypass VXLAN tunnel source IP address; and the first PE obtains a detection result from the response packet. The first PE may receive the response packet, so that the first PE can obtain the detection result.

  • Publication number: 20220231937
    Abstract: A first provider edge (PE) determines whether a link between the first PE and a second PE is a high latency link, where the second PE is a next hop of the first PE. When determining an actual latency corresponding to the link, the first PE compares the actual latency with a first latency threshold. When the actual latency is greater than or equal to the first latency threshold, it indicates that the actual latency exceeds a latency upper limit corresponding to the link, the first PE determines that the link is a high latency link. In this way, it is not necessary to wait for network management personnel to determine whether the link is a high latency link. After determining the actual latency corresponding to the link, the first PE can determine in time whether the link is a high latency link.

  • Patent number: 10841709
    Abstract: A membrane hetero-structure includes a polymer layer and a single-layer or multi-layer graphene sheet disposed on the polymer layer. The membrane hetero-structure is tensioned across a frame having an opening such that both the polymer layer and the graphene sheet extend across the opening. An optional rigid member is provided in a center of the membrane to be spaced apart from edges of the opening. The assembly of the frame and membrane hetero-structure forms an electrostatically driven micro-electro-mechanical system (MEMS) or sound generation and recording apparatus. In one instance, when a voltage signal is applied between an electrode layer parallel to the membrane and contacts on the frame that are electrically connected to the graphene sheet, the membrane hetero-structure is actuated.
