Abstract

The embodiment of the invention discloses a data flow control method and device, an electronic device and a storage medium. The method comprises: receiving information of file blocks generated by alllink nodes to obtain a file block information list; according to the file block information list and the throughput of each link node, determining a plurality of file blocks needing to be received bya next scheduling window and predetermined uploading time of each file block in the plurality of file blocks; respectively sending control information to link nodes associated with the plurality of file blocks according to the predetermined uploading time of each file block, so that each link node uploads the locally cached file block to be received at the corresponding predetermined uploading time according to the received control information; and after receiving the file blocks transmitted by each link node, forming a file according to the information of each file block and storing the file.According to the embodiment of the invention, the occurrence of network congestion can be inhibited or prevented, and a flow control effect can be achieved for data transmission of an application layer protocol.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of the Internet of Things, and in particular to a data flow control method, device, system, electronic equipment, and storage medium. Background technique [0002] In the transport layer of the TCP / IP protocol family, the sliding window is usually used to implement flow control, which mainly refers to the control of point-to-point traffic, and solves the problem of end-to-end. [0003] In a distributed network topology, once all data senders transmit data to data receivers, network congestion may occur on branch switches, so that routers or links in the network are overloaded. Contents of the invention [0004] In view of this, the embodiments of the present disclosure provide a data flow control method, device, system, electronic equipment, and storage medium, so as to avoid network congestion. [0005] Other features and advantages of the embodiments of the present disclosure will...
