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.
