【摘要】：车载通信网络管理(NM)系统的性能直接影响到汽车电子网络通信安全.对OSEK NM中逻辑环机制实际运行状态进行建模,建立各工作状态间转换模型;引入NM诱导报文和逻辑环不稳定时间,定量分析OSEK NM逻辑环不稳定工作状态,推导出度量逻辑环工作性能的计算公式;提出一种支持第二直接后继的逻辑环建环机制,给出该机制下逻辑环的工作性能.实验结果表明:相对于OSEK NM,支持第二直接后继的建环机制不仅能够提高车载NM的实时性,而且能有效降低NM对用户报文传输的不良影响.
[Abstract]:The performance of vehicular communication network management (NM) system directly affects the communication security of automotive electronic network. The actual running state of logical loop mechanism in OSEK NM is modeled, and the transformation model of each working state is established. The NM induced packets and the unstable time of the logical loop are introduced to quantitatively analyze the unstable working state of the OSEK NM logical loop, and the calculation formula to measure the working performance of the logical loop is derived. In this paper, a mechanism supporting the second direct follow-on logical ring construction is proposed, and the working performance of the logical ring is given. The experimental results show that compared with the second direct successor mechanism supported by OSEK NM, the mechanism can not only improve the real-time performance of on-board NM, but also effectively reduce the adverse effect of NM on the transmission of user messages.
