A bandwidth bottleneck is a phenomenon where the performance of a network is limited because not enough bandwidth is available to ensure that all data packets in the network reach their destination in a timely fashion. Thus, bandwidth bottlenecks lead to slow and unresponsive applications, and therefore to a loss of productivity and money.

Data transmission method and apparatus based on bottleneck bandwidth and round-trip propagation time algorithm
This application discloses a data transmission method, apparatus, storage medium, and electronic device based on bottleneck bandwidth and round-trip time algorithms. The method includes: generating adjustment parameters based on the relative relationship between the current round-trip time of the data stream and the minimum round-trip time of the link within each bandwidth probe transmission cycle, and applying these parameters to the control of the transmission rate and duration of a specific sub-cycle in the next transmission cycle. This achieves the goal of proactively and adaptively balancing the bandwidth resource occupation of each stream in concurrent multi-data stream scenarios, thereby significantly improving the fairness of multi-stream competition, effectively dealing with network round-trip time jitter, and optimizing the overall throughput efficiency of highly dynamic shared links. This solves the technical problem of low utilization efficiency of data transmission links in related technologies.
