As an example of normal versus breakout subgroups, consider the two hierarchies of groups shown in figure 1.

作为普通子组与断接子组的例子，可以考虑两个组层次结构，如图1中所示。

From figure 1, we can see that groups are composed of protocols, networks and storages.

如图1所示，分组由协议、网络和存储构成。

This TLU classifies these inputs into two groups: the 1 group and the 0 group.

TLU将这些输入分为两组：0组和1组。
