摘要
提出一种新的二层组播在工业自动化领域中应用的方案,解决了由二层设备构成的工业以太网中组播数据流扩散问题。分析了方案的实现机制,并引入可靠组播传输协议和Qos思想对网络性能进行了优化。
In this paper a new application of two - layer multicast in industrial automation is presented,used to solve the multicast traffic flooding problem in the industrial LAN,which consisted of two-layer switch.The basic mechanism of application is ana- lyzed in this paper.At the same time,the reliable multicast idea and Qos are used to optimize the network.
