| 摘 要： | 在AFDX的传输控制过程中，不但要进行数据的传输、队列资源的管理，还要提供区分服务，以满足不同等级任务的服务质量要求。文章介绍了AFDX中基于区分服务的队列管理算法，改进了现有算法的不足，从而更加合理地分配带宽资源，平衡系统吞吐量和分组排队延迟之间的矛盾，保证不同等级用户之间的公平性，以获得最优化的AFDX网络。

| Abstract: | In the course of transmission control for AFDX, the data transmission and queue-buffer management is carried out while the differentiated service is provided to meet the QoS requirements of different levels＇ tasks. The article describes several algorithms of queue management based on differerntiated services in AFDX, and the improvement on the existing algorithms, Thus the distribution of bandwidth buffer becomes more reasonable, and the contradiction of system throughput and packet queuing delay is balanced, the fairness of the users in different levels ensured and the optimal AFDX network obtained. |
