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。

Abstract

By analyzing the characteristics of every type of messages, two bandwidth allocation strategies of MVB aperiodic communicationwere proposed , and relevant formula was derived. In combination with the scheduling principles of aperiodic messages, theoptimized bandwidth allocation strategy were researched and compared. The real-time performance of aperiodic messages had greatlyimproved after the optimization of bandwidth allocation.
