The Switch of AFDX adopted policing technology to ensure that the data in every virtual link transmit as a fixed speed. On these grounds it can achieve the flow control of AFDX
and guarantee the determinacy and reliability for AFDX. According to the ARINC664 specification
a policing algorithm for the AFDX switch is given out
and the design of the algorithm was completed. The simulation experiments show that the design has good effect on flow control.
