    摘要： A technique for monitoring a redundancy status of a connection established between a User Equipment, UE, and a cellular network is disclosed, wherein the connection is established using redundant communication paths between the UE and the cellular network. A method implementation of the technique is performed by a first node of the cellular network and comprises triggering determining a current redundancy status of the connection, the current redundancy status indicating whether or not the redundant communication paths are fully disjoint on at least a portion of the redundant communication paths, and triggering sending a redundancy notification to a second node of the cellular network, the redundancy notification including an indication of the determined current redundancy status.

    摘要： Disclosed are a method and device for data transmission. The method comprises: before a transmitting end receives feedback information, the transmitting end continually transmits multiple packets carrying same information to the receiving end, the feedback information carrying indication information used for indicating whether the receiving end correctly receives at least some packets of the multiple packets; the transmitting end receives the feedback information transmitted by the receiving end; and the transmitting end transmits subsequent data on the basis of the feedback information. In the solution, the transmitting end can continually transmit multiple packets carrying same information to the receiving end until the transmitting end receives the feedback information transmitted by the receiving end, and the transmitting end then determines subsequent data transmission on the basis of the feedback information. In such data transmission mechanism, because a transmitting end continually transmits packets carrying same information to a receiving end, the reliability of data transmission is increased.

    摘要： A distributed system includes a plurality of compute nodes configured to process messages. The compute nodes each process messages corresponding an assigned value of a common parameter of the messages. The values are assigned to the compute nodes such that two or more compute nodes are available to process each message. The values can be assigned to the compute nodes in a grouping configuration or a striping configuration. The compute nodes also circulate one or more tokens among nodes, and perform a self-maintenance operation during a given state of possession of the token. During a self-maintenance operation, the values assigned to the compute node can be reassigned to other compute nodes to ensure processing of corresponding messages.

    摘要： A master device manages a plurality of slave devices constituting a network including a ring topology. The plurality of slave devices includes: a first slave device serving as a starting point and a terminal point of the ring topology; and a plurality of second slave devices connected between a first output port of the first slave device and a second output port thereof and constituting the ring topology. On the basis of a network configuration detected when the second output port and the output port of a second slave device paired with the second output port are available and of a network configuration detected when the second output port and the output port paired therewith have been made unavailable, the master device determines an incorrect wiring path between the first output port and the second output port and outputs information indicating the incorrect wiring path to an information processing device.

    摘要： Systems and methods for Managed Network Traffic Prioritization (MNTP) are described. In an embodiment, an Information Handling System (IHS) operated by an Information Technology Decision Maker (ITDM) or administrator may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: identify one or more priorities applicable to network traffic handled by a client device based, at least in part, upon telemetry data received provided by the client device; and transmit, to the client device, a policy determined based, at least in part, upon the one or more priorities, wherein the client device is configured to apply the policy to the network traffic.

    摘要： A method for processing a data packet at a node in a Bluetooth Mesh network, comprising: (a) determining a one-hop device cache list of the node, wherein the one-hop device cache list comprises an address of one or more one-hop nodes; (b) when the node sends a data packet, checking whether a destination address of the data packet is the same as an address stored in the one-hop device cache list; if yes, setting a TTL value of the data packet to 0 and sending the data packet; otherwise, setting the TTL value of the data packet to be greater than a specified TTL threshold, and sending the data packet; and (c) when the node forwards a data packet, checking whether the destination address of the data packet is the same as an address stored in the one-hop device cache list; if yes, setting the TTL value of the data packet to 1 and forwarding the data packet; otherwise, deducting the TTL value of the data packet by 1 and forwarding the data packet. According to the present disclosure, the problem of signal interference in a dense Bluetooth Mesh network may be significantly reduced.
