求翻译：（3）采用星型网络拓扑结构，功能强大的交换机可将网络细分为若干个网段。交换机之间，通过主干网络进行连接。交换机可对网络上传输的数据进行过滤处理，使每个网段内的节点之间数据的传输只限制在本地网段内进行而不需要经过主干网。使本地数据传输不占其它网段的带宽，从而，大大降低了所有网段和主干网的网络负荷。是什么意思？

Switches on the network can transmit data filtering, so that each network segment between the nodes is only limited data transmission without
