摘要: AFDX交换机主要采用流量警管技术来确保网络传输过程中每条虚链路的数据按照既定的速度传输.据此实现对AFDX网络的流量控制, 从而保证AFDX网络数据传输的确定性、可靠性.基于ARINC664规范, 提出了一种AFDX交换机警管算法, 完成了该算法的设计实现, 并通过仿真实验证明了该设计具有良好的流量控制效果.Abstract: 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.
