对AOS协议中的自适应帧生成算法进行研究,通过严格地理论分析,给出了该算法的有效信息传送速率计算公式。进一步,将数据帧生成模块与虚拟信道复用模块作为一个整体进行考虑,针对现有的AOS多路复用技术的不足,提出了自适应帧生成算法与虚拟信道调度算法相结合的多路复用新方法。研究结果表明,通过在多路复用中应用自适应帧生成算法,并设置合理的帧生成时间门限值,可以比目前主要使用的、采用高效率帧生成算法与虚拟信道调度算法相结合的多路复用方法获得更好的包时延性能。
The adaptive frame generation algorithm in AOS protocol is studied.Theoretical analysis is strictly performed to get the formula for computing the effective information transmission rate of the adaptive algorithm.A novel multiplexing method is also proposed by combing the adaptive frame generation algorithm with the virtual channel scheduling algorithm together into a whole multiplexing module.Simulation results show that by setting an appropriate threshold of the adaptive frame generation algorithm,the proposed multiplexing method can get better packet time delay performance than the current multiplexing methods,in which the high efficiency frame generation algorithm is used.
