An availability calculation device includes a bandwidth notification information storing unit that stores received bandwidth notification information for a certain period, and an availability calculation unit that calculates an availability for each bandwidth of a wireless link by using the bandwidth notification information stored in the bandwidth notification information storing unit.

A method for network transmission, a device, and a storage medium, which relate to a field of a computer technology, in particular to a field of a network transmission technology. The method includes: detecting current loads of a plurality of peer ports of a network node in a network; determining a target peer port with a largest current load from the plurality of peer ports; marking a message currently transmitted by the target peer port, so as to obtain a marked message; and sending the marked message to a terminal corresponding to the marked message or a server corresponding to the marked message.

A reactive buffering system for use in IIoT data pipelines dynamically adjusts data accumulation and delivery by a node of a pipeline based on aggregated downstream metrics representing current data processing latencies of downstream nodes. Based on these downstream performance metrics, a reactive node that adjusts the size of the next data batch to be sent to an adjacent downstream node. The nodes of the data pipeline are configured to support a request-response based handshaking protocol whereby the nodes that send data to downstream nodes maintain up-to-date performance level information from adjacent downstream nodes. With this performance information, together with pipeline priorities, the sending node (or reactive node) adjusts the transmission rate and intermediate buffering of data. In this way, the nodes of the pipeline can dynamically regulate interim data storage to avoid overwhelming the pipeline system with too much data during periods of high latency.

This application provides a data transmission method and apparatus. The method includes: determining a first sending rate based on a network performance objective of first data and a network status of a first transmission control protocol (TCP) connection of a transport layer protocol, where the first TCP connection is used to send the first data; and sending the first data based on the first sending rate. In this way, network congestion control is more flexible, and TCP-based data transmission efficiency is improved.

In an example, a Dynamic Host Configuration Protocol (DHCP) lease request from a client device connected to a network is received. Based on the DHCP lease request, an Internet Protocol (IP) address is assigned to the client device for a lease time. A first lease renewal request is received. A probability of utilization for a lease time block is predicted based on a historical lease pattern, device characteristics, traffic information, and DHCP information. Based on a combination of the probability of utilization and a reward value, the lease time block is allotted for lease renewal. For each allotment, the reward value is adjusted based on deployment characteristics and traffic load in the network, and a network connection duration of the client device. A normalized reward value for the lease time block is determined based on reward values for the lease time block over multiple allotments.

Electronic communications received via a network from a plurality of electronic devices may include signals of device interactions or data changes that correspond to process performances by process-performing resources, signals of conditions of loads, or signals of processes associated with the process-performing resources and the loads. Data composites may be formed from the electronic communications, with data portions collected and mapped to resource profile records and load profile records that may be updated with the collected data portions. For each load, at least one of the one or more resource profile records and/or the one or more load profile records may be used to map the process-performing resources to the load. Content nodes may be linked in a network of content nodes, including respective linked content, resource specifications or load specifications. Access to the network of content nodes may be allowed via a control interface.
