摘　　要：针对嵌入式网络系统动态一对多通信中,CPU开销与网络流量的平衡问题,通过分析、比较这种网络通信模型,提出了一种有效的解决方案———D irectX技术,并对其作了详细的描述,该技术能取得网络单播和广播技术两者的优点。最后通过一个应用实例,分析、证明了这种技术的有效性。The balance of CPU-cost with networks-traffic, which is in the communications of point to multipoint dynamic with regard to embedded networks system was introduced. To begin with, the models of networks communications were analyzed and compared. Then, an effective solution with its description, DireetX technique, was followed, which can benefit specifically from the merit of both unicasting networks and broadcasting networks. Last, it was achieved to analyze and prove the validity of the solution by an application instance.
