工业以太网采取了以下措施使得该问题基本得到解决：
1.采用快速以太网加大网络带宽。
Ether-net的通信速率从10、100 Mb/s增大到如今的1、10Gb/s。在数据吞吐量相同的情况下，通信速率的提高意味着网络负荷的减轻和网络传输延时的减小，即网络碰撞机率大大下降，从而提高其实时性。
2.采用全双工交换式以太网。
用交换技术替代原有的总线型CSMA/CD技术，避免了由于多个站点共享并竞争信道导致发生的碰撞，减少了信道带宽的浪费，同时还可以实现全双工通信，提高信道的利用率。
3.降低网络负载。
工业控制网络与商业控制网络不同，每个结点传送的实时数据量很少，一般为几个位或几个字节，而且突发性的大量数据传输也很少发生，因此可以通过限制网段站点数目，降低网络流量，进一步提高网络传输的实时性。
4.应用报文优先级技术。
在智能交换机或集线器中，通过设计报文的优先级来提高传输的实时性。2 PRI BM302960200 Brooks 30296 Brooks assy BD Motor Prog Xfer
