摘　　要：VxWorks具有良好的可裁减性、可靠性和卓越的实时性,广泛地应用于航天、航海等实时性要求很高的领域中。Vx-Works有2种Socket调用:与BSD4.4源码兼容的Socket调用和Zbuf的Socket调用。在系统高实时通信中,与BSD4.4源码兼容的Socket调用很难满足要求,而Zbuf的Socket调用具有更高的数据传输速率。将以上方法应用于系统高实时通信的程序设计中做出对比。并给出了部分源代码作为示例说明。Because VxWorks system has good reliability, excellent real-time correspondence and can be reduced to meet specifically requires ,it is widely used in many fields such as spaceflight and navigation, which needs high real-time correspondence. There are two kinds of Socket in VxWorks, one is the Socket which compatible with BSIM. 4,the other is Zbuf of Socket. In the system high real-time communications, the Socket which compatible with BSIM. 4 is undesirably and the Zbuf of Socket is better at Transmission Performance. In this paper, there is a comparison between above methods with experiments in the system high real-time communications and some source codes about network communications are illustrated as examples.
