摘要
在分析MVB数据传输机制的基础上,提出了非周期数据通信的优化带宽分配策略,推导出了相应的带宽分配策略的计算公式,并在实例中对优化后的策略进行了分析研究和性能比较。对带宽分配方法进行优化后,非周期数据通信的实时性有比较明显的提高。
By analyzing the characteristics of every type of messages, two bandwidth allocation strategies of MVB aperiodic communication were proposed, and relevant formula was derived. In combination with the scheduling principles of aperiodic messages, the optimized bandwidth allocation strategy were researched and compared. The real-time performance of aperiodic messages had greatly improved after the optimization of bandwidth allocation.
