  • Patent number: 10164893
    Abstract: A method and an apparatus acting as a server for estimating parameters of data transfer across a communication network are provided. The server includes a transceiver which enables data transfer operations and an estimator which estimates throughput as one of the parameters of the data transfer operations. The estimator further determines an indicator value of the throughput corresponding to an estimated bottleneck bandwidth (eBnBW) calculated from data traffic measurements. The indicator value is attributable to and indicates optimal parameters of the data transfer operations, calculated from measurements associated with the data traffic. The server apparatus includes a processor, in communication with the transceiver and the estimator, and the processor is configured to control for preparing succeeding data transfer operations to a client apparatus through the communication network based on the estimated bottleneck bandwidth determined by the estimator.
