工业路由器:组播数据包的二层交换

网桥或二层交换机(以下统称二层交换机)是工作在二层的网络设备。当它们收到工业路由器组播数据包后如何处理?最简单的处理方式就是当网桥从一个接口收到全网通工业级路由器组播数据报后向所有其它接口都转发出去。一般的没有组播功能的二层交换机都是这么处理的,所以这样的网桥也最便宜。但是这样处理就偏离的工业级路由器组播的初衷。

然而,具有组播功能的二层交换机可以做到只在需要的接口上才转发工业无线路由器组播数据。那么如何实现 ?

二层交换机将在转发表中添加一项:MAC地址是组播地址,端口包含与希望接收到工业级无线路由器组播数据的主机相连所有的端口。以后当二层交换机接收到组播数据报后,将向除接收端口外的所有转发表项的其它工业4G路由器希望接收组播数据的端口转发组播数据。

4g路由器:组播技术的特点

工业4g路由器IP组播技术有效地解决了单点发送多点接收、多点发送多点接收的问题,实现了工业3G路由器IP网络中点到多点的高效数据传送,能够有效地节约网络带宽、减轻服务器及网络的负载。因此具有增强效率,优化性能,分布式应用等优点。

由于工业级3g路由器IP组播是基于UDP的,所以全网通工业路由器IP组播也可能有信息包传送不可靠、信息包重复、信息包不按序到达、无流量控制等缺点。4g无线路由器
