At the same time , according to the special network communication requirement of real - time computing system , the proposed protocol takes advantage of tcp and udp protocols , and introduces token - control , incorporate with network management measures such as multi - layer error control , master - slave broadcasting , non - equality net accessing , etc . all these make ethernet a logical real - time network . this protocol provides a transparent data transmit system for the software of upper level application 同时，该协议根据实时计算系统对网络通信的特殊要求，结合tcp和udp网络协议的优点，加入了多级差错控制、主从广播发送、非平等网络访问等管理措施，使得以太网成为一种逻辑上的实时网络。
