The embodiments disclose a method and apparatus of selecting a path for transmission from paths between a first LER and a second LER in the MPLS network. The method may comprise: obtaining state information of the paths between the first LER and the second LER, the state information may indicate that a path is in up state or down state; obtaining stability information of at least one of the paths between the first LER and the second LER, the stability information may indicate that a path is stable or unstable; and selecting a path for transmission based on the state information and the stability information.

Provided is a distributed scheduling method and apparatus for resource allocation for Device-to-Device (D2D) communication. The method includes sending, by a Mobile Station (MS) including data to transmit, a first resource reservation message through at least one first slot among a plurality of slots constituting a resource reservation unit in a resource reservation channel; and when a second resource reservation message sent by another MS is not sensed in a slot with a higher priority than the first slot in the resource reservation unit, transmitting the data through a transmission resource unit corresponding to the resource reservation unit in a data transmission channel. The resource reservation channel corresponds to the transmission resource unit, and the plurality of slots has mutually cyclic priorities.

A method and apparatus for improving forwarding performance of a chip are disclosed. The method includes: when a chip receives a message, judging whether the message is a protocol message required to be processed, if the message is the protocol message required to be processed, performing MAC learning, and if the message is not the protocol message required to be processed, determining whether to perform learning after performing calculation according to a current actual time value of the chip and a preset empirical value. The apparatus includes: a first judgment module and a second judgment module. With the method and apparatus of the embodiments of the present document, an MAC learning intensity of the chip can be relieved to a great extent, thereby improving the forwarding performance of the chip.

A congestion control mechanism for TCP communication sessions is described. The congestion control mechanism adjusts the size of the congestion window based on a number of parallel virtual TCP Hybla connections. The number of parallel virtual TCP Hybla connections used to determine the congestion window can be dynamically adjusted. The enhanced TCP Hybla congestion control mechanism provides improved throughput for heterogenous networks having a high latency link and having possible packet loss.

A flight management system for unmanned aerial vehicles (UAVS), in which the UAV is equipped for cellular fourth generation (4G) flight control. The UAV caches on-board a 4G modem, an antenna connected to the modern for providing for downlink wireless RF. A computer is connected to the modem. A 4G infrastructure to support sending via uplink and receiving via downlink from and to the UAV. The infrastructure further includes 4G base stations capable of communicating with the UAV along its flight path. An antenna in the base station is capable of supporting a downlink to the UAV. A control centre accepts navigation related data from the uplink. In addition, the control centre further includes a connection to the 4G Infrastructure for obtaining downlinked data. A computer for calculating location of the UAV using navigation data from the downlink.

A system comprises premises devices located at a premises. A gateway device is located at the premises and may communicate with the premises devices. A server is configured to interact with the premises devices and the gateway device. A touchscreen device may communicate with the server and configured to interact with the premises devices. The touchscreen device includes a user interface configured to interact with the gateway device. The user interface is configured to control interactions between the premises devices and the gateway device and trigger, based on at least one automation rule, an action of at least one of the premises devices. Corresponding methods, apparatuses and other systems are also provided.

A device control method, a server, a system and a computer storage medium are provided. The method includes: receiving account information, a device identifier and a device control instruction sent by a user terminal (S101); acquiring a universal infrared controller identifier corresponding to the device identifier, and infrared pulse parameters corresponding to the device control instruction (S102); sending the infrared pulse parameters to the universal infrared controller corresponding to the universal infrared controller identifier through a home gateway corresponding to the account information; wherein the infrared pulse parameters are provided for the universal infrared controller to generate an infrared pulse instruction used to control a device corresponding to the device identifier to execute a corresponding operation (S103).

According to an example, a counter update determination module may receive a counter address for a local counter and map the counter address to a specific forwarding mode of a plurality of forwarding modes. In addition, a remote processing module may receive a posted value associated with the local counter. The remote processing module may include a plurality of forwarding engines respectively associated with a mapped forwarding mode. A forwarding engine of the plurality of forwarding engines may be selected based on the mapped forwarding mode, and the selected forwarding engine may forward the posted value to a remote device for remote processing.

A shutter control system for use with a network. The shutter control system includes a network device coupled to the network to communicate an indication. The shutter control system also includes a shutter controller configured to receive the indication, to determine if the indication meets a predefined condition, and, in response to the indication meeting the predefined condition, to communicate an actuation signal. A shutter device, having at least one motor, receives the actuation signal, and operates the at least one motor based on the received actuation signal.

Systems and methods associated with service insertion forwarding are disclosed. One example method includes building a service insertion address table. The service insertion address table may associate service insertion tunnels with device addresses based on payload source addresses retrieved from packets received via the service insertion tunnels. The method also includes forwarding a packet received from a source device to a destination device. The packet may be received from the source device via a source service insertion tunnel. The packet may be forwarded to the destination device via a destination service insertion tunnel. The destination service insertion tunnel may be associated with the destination device in the service insertion address table.
