Abstract

The invention relates to a test method for time-sensitive network data frame scheduling, and belongs to the technical field of communication. The method comprises the following steps: a network topology structure of test equipment and DUT is built; on the premise that time synchronization between the equipment is completed, Talker sends test data to the DUT, the test data is forwarded to Listner after being scheduled by a time sensitive network, and the test equipment extracts a flow characteristic analysis scheduling sequence. The method is used for testing a gating function, a time sequencefunction, a scheduling precision and gating precision of the scheduled time sensitive network, and verifying whether a time sensitive network scheduling mechanism is correctly realized by the DUT or not.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a test method for time-sensitive network data frame scheduling. Background technique [0002] Time Sensitive Networking (TSN) is a family of technologies that can provide deterministic latency. At present, the standards for time-sensitive networks mainly stipulate three types of functions, such as time synchronization, dispatch communication, and system configuration. By increasing the deterministic and low-latency requirements of communication, it can eliminate the last obstacle that standard Ethernet cannot become the main backbone network. , to promote the convergence of critical and non-critical control information and data into a single network, and truly realize one network to the end. [0003] Time synchronization is the basis of time-sensitive network scheduling communication, and scheduling communication is the core to achieve low latency. The IEEE802.1Qbv standard...
