Example Embodiment
[0024] Example one
[0025] The AFDX network switch performance test scheme involved in this embodiment includes two configurations:
[0026] 1) Parameter configuration of AFDX network switch
[0027] For the AFDX network performance test, because the data forwarding rate is very fast, and the configuration of the virtual link of the AFDX network switch is controlled by the configuration parameters in the switch configuration table, it is necessary to configure a reasonable number of virtual links for each port of the AFDX network switch The link and the BAG of each virtual link can meet the requirements of wire-speed forwarding. If the test equipment sends frames at a wire-speed rate, but the number of virtual links configured for each port is small, then the data frames allocated to each virtual link will be discarded by the switch policing function because they are smaller than the BAG. The number of virtual links of the port is designed reasonably.
