Problems solved by technology

Although this method can make the picture cache more reasonable and efficient, there is also a problem. When the teacher switches to one of the pictures, since only a few of the student-side devices have already cached the picture, most of the remaining devices need to Download the picture at the same time quickly and display it. If it is not controlled according to the current network conditions, it will inevitably cause network congestion, reduce the efficiency of downloading pictures, and cannot effectively use network bandwidth, resulting in a waste of network bandwidth.

Abstract

The invention discloses a picture loading method and device, and the picture loading method and device are used for increasing the picture downloading speed by controlling network flow. The picture loading method includes the steps of receiving a picture switching instruction from a master device, wherein the picture switching instruction comprises marks of current pictures; determining the number of first auxiliary devices not caching the current pictures; controlling the first auxiliary devices to download the current pictures according to the number and a current network flow value. Devices are controlled according to the current network situation and the number of devices needing to download the pictures, so that the devices download the pictures to be displayed preferentially. Meanwhile, the network bandwidth can be utilized more effectively, the picture downloading speed is increased, and network congestion is avoided.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a picture loading method and device. Background technique [0002] In applications such as teaching or exhibitions, it is usually necessary for multiple devices to download pictures from the server at the same time for viewing. Taking the teaching scene as an example, the teacher opens the PPT or Word lesson plan, and when the teacher browses the picture on his own device, the student device will automatically download the picture from the server along with the teacher's device for browsing. This method for multiple devices to download pictures in real time is likely to cause network congestion and slow picture download speed. [0003] To solve this problem, multiple devices can first cache the pictures in the server in the background. When the teacher opens the PPT or word lesson plan, the device on the student side will cache the pictures sequentially according ...
