The invention discloses a quality of service (QOS) level control method, device and system, wherein the method includes: setting the traffic sent and received by the Openflow switch as traffic of multiple levels; acquiring the traffic of each level in sequence, and judging the traffic according to the order of the levels Whether it exceeds the preset safety threshold; if yes, locate the excess service flow in hierarchical order; when the excess service flow is at the flow table level of the Openflow switch, send the flow table to the Openflow switch and delete This excess traffic flow. The QOS level control method, device and system of the present invention can realize the scheduling control of multi-level and multi-bottleneck points, and can define the priority of service flow according to the needs of users, so as to ensure the QOS of service flows with high service priority; The bandwidth between rooms and applications is mutually crowded, and at the same time, bandwidth resources can be shared to the maximum extent, and the QOS of designated services can also be guaranteed. Improve network service efficiency.
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...
