Problems solved by technology

This often leads to a dilemma for operators, either to give up the multicast method due to the high packet loss rate, or to spend several times or even higher costs to replace network devices with better performance
How to effectively multicast files in cloud systems with high packet loss rate has not been reported yet

Abstract

The invention provides a high-packet-loss-rate cloud system file multicast method and device. Files (especially large files) can still be stably transmitted in a multicast mode when the packet loss rate of cloud system network equipment (network cards, concentrators, switches, routers, etc.) reaches the level of 0.1%, the situation of data packet loss can be timely discovered in the multicast process, and all the relevant instance systems are ensured to correctly receive the files through combination of multiple times of multicasting and independent transmission.

Description

technical field [0001] The invention relates to a method and a device for multicasting files in a cloud system with a high packet loss rate. Background technique [0002] A certain operating system (such as the Android operating system) plus the necessary hardware (such as processors, memory, etc.) required to run the operating system can be regarded as an instance system, in which various applications can be run (applications refer to the software or programs running on the operating system of the instance system). A cloud system can be formed by centrally managing several instance systems according to a certain architecture (such as distributed). Usually, the operator is responsible for the daily operation of the cloud system and provides services for users. [0003] In many cases, operators need to install a certain application on a large number of instance systems, or upgrade the operating systems of all instance systems (for example, the operating system has issued a ...
