The invention relates to a QOS (
Quality of Service)
strategy selection and
queue scheduling method of a base switching network, which is characterized by comprising the following steps of: firstly, after network equipment receives a data frame, executing a QOS
strategy selection operation by the network equipment, selecting a priority mapping table corresponding to the data frame from five different priority mapping tables, querying in a priority mapping table corresponding to the data frame to obtain a priority ID of the data frame; then, the network equipment queries a priority ID
queue mapping table based on the priority ID of the data frame to obtain an output
queue ID, and inserts the data frame into an output queue corresponding to the output queue ID; and finally, the network equipment transmits the output queue with the data frames to receiving equipment at an output port through a weighted
polling scheduling (WRR)
algorithm. According to the method and the device, a plurality of priority mapping tables are preset, so that the QOS model can process the data frames in various formats, and the types of compatible and supported
data traffic are expanded.
