Abstract

The invention discloses a method, a device and a system for service quality QOS level control. The method comprises steps that the flow transceived by an OpenFlow switch is set as the multi-level flow; the flow of each level is acquired, and whether the flow exceeds the preset safety threshold is determined according to the level order; if yes, the exceeding business flow is positioned according to the level order; when the exceeding business flow is a business flow of a flow table level of the OpenFlow switch, a flow table is issued to the OpenFlow switch, and the exceeding business flow is deleted. According to the method, the device and the system for service quality QOS level control, multi-level multi-bottleneck-point scheduling control can be realized, priority of the business flow can be defined according to demands of a user, and QOS of the business flow with high business priority is guaranteed; mutual bandwidth occupation among users and among applications can be reduced, moreover, bandwidth resources can be shared to the maximum degree, and the designated business QOS can be further guaranteed, and network service efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of flow management, in particular to a QOS level control method, device and system. Background technique [0002] The broadband access network of telecom operators is a tree-shaped or star-shaped aggregation network. Generally, there are multiple bottlenecks. When the network is congested, the processing will be very complicated and costly. Generally, the Internet broadband access section generally adopts a star or tree structure, and is generally aggregated step by step by an Ethernet switch, and its root is a BRAS (Broadband Access Service Point). Due to the limited coverage and capacity of the access network, the random behavior of users surfing the Internet will have a greater impact on the network, and congestion and other users will often be affected. There are many access network devices with varying capabilities, and it is difficult to deploy a unified QOS policy on each device. When the ne...
