The model is analogous to a connection-oriented networking protocol or the Open Systems Interconnection-layered architecture. 這個模型與面向連接的連網規約相似，即類似于分層的開放系統互連結構。
These basic switches conform to the Open Systems Interconnection layer 2 protocol and operate as fast bridges, meaning they are transparent to network layer protocols. 這些基本的交換機符合開放系統互連模型第二層協議，并作為快速網橋工作，這意味著它們對網絡層協議是透明的。
