Network performance evaluation method for traffic queuing based on CBS shaping mechanism

The invention discloses a network performance evaluation method for traffic queuing based on a CBS shaping mechanism. According to the method, network performance evaluation is carried out on a constructed TSN network. According to the invention, the method includes analyzing the constraint effect of a CBS shaping mechanism on flow transmission; for the TSN network, based on a TAS mechanism, sending CDT type traffic; considering a time slot of CDT type flow distribution as a leaky bucket model; calculating the maximum delay value of the Class A type flow and the Class B type flow and the maximum backlog amount of a queue when the Class A type flow and the Class B type flow are queued respectively through an arrival curve of the Class A type flow and the Class B type flow and a service curve of a network node under a constructed CBS shaping mechanism. Through the method provided by the invention, the network delay caused by traffic queuing under the CBS shaping mechanism can be reduced, so that guidance is pro
