Bandwidth adjustment method and system based on service priority, and storage medium

The invention discloses a bandwidth adjustment method and system based on business priorities and a storage medium, and the method comprises the steps: dividing businesses into a first priority business, a second priority business, a third priority business and a fourth priority business according to different business demands when the businesses need to be subjected to bandwidth allocation; carrying out bandwidth allocation on the four types of priority services according to different allocation rules; while the bandwidth requirement of the high-priority service can be met as far as possible, the bandwidth utilization rate of the channel is improved, and the number of services which cannot be met by the bandwidth requirement is reduced. 本发明公开了一种基于业务优先级的带宽调整方法、系统及存储介质，包括：当需要对业务进行带宽分配时，根据不同的业务需求将业务划分为第一优先级业务、第二优先级业务、第三优先级业务和第四优先级业务；根据不同的分配规则对四类优先级业务进行带宽分配；能够尽可能满足高优先级业务的带宽需求的同时，提高信道的带宽利用率并减少带宽需求得不到满足的业务数量。
