Abstract: A ship cabin loading capacity measurement method and apparatus thereof, comprises: acquiring point cloud measurement data of a ship cabin; optimizing the point cloud measurement data according to a predetermined point cloud data processing rule, and generating optimized ship cabin point cloud data; calculating said ship cabin point cloud data with a predetermined loading capacity calculation rule, and getting ship cabin loading capacity data. According to the ship cabin loading capacity measurement method of the present invention, the point cloud measurement data can be acquired by a lidar, and processing the point cloud measurement data of the ship cabin with a predetermined point cloud data processing law and a computation law, and as the point cloud data processing law and the computation law can be deployed in a computer device in advance, after point cloud measurement data acquisition, loading capacity of a ship cabin can be acquired quickly and precisely.

Abstract: A device for measuring volume of spherical tanks, includes a base, four supporting rods, a driving mechanism, a rotating disc and a counterweight mechanism. The base is provided with a first through hole and a circular fixing base with a second through hole. The supporting rods are circumferentially provided on the fixing base, with a sliding rod slidably provided at the lower side. An outer end of the sliding rod is provided with a limiting plate. The driving mechanism can drive the sliding rods to move simultaneously in radial directions. The rotating disc with a third through hole is arranged on the fixing base, and is rotatably provided with a reel around which a steel tape is wound. A free end of the steel tape is provided with a balancing disc whose opposite sides are provided with laser rangefinders. The counterweight mechanism can keep the balancing disc stable.

Abstract: This application provides a packet processing method, including: receiving, by a current network node, a first packet; determining, by the current network node, a flow identification corresponding to the first packet, where the first packet does not include the flow identification; obtaining, by the current network node based on the first packet and the flow identification, a second packet, where the second packet includes the flow identification and an IOAM header, and in the second packet, the flow identification is located before the IOAM header; and sending, by the current network node, the second packet to a next network node. This resolves a problem that as a quantity of passed IOAM nodes increases, traffic classification performed by a subsequent node consumes a longer delay, thereby deteriorating forwarding performance.

Abstract: A 1+1 protection method of service in optical burst switching (OBS) networks, an intersection node apparatus, and protection system of service are provided. The method discloses that burst packets bearing service are transferred through two risk-independent routes, and each burst packet corresponds to a control packet. The intersection node receives a first control packet transferred through either route with a sequence number, and then, when it continues to receive the second control packet, which is transferred through the other route with the same sequence number as the first control packet carries within the waiting time of the first control packet, the intersection node selects the burst packet corresponding to the control packet with a smaller quality loss field value of the first and second control packets. The present invention prevents the services from being cut down, and remarkably reduces the packet loss ratio of the service.
