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 这些基本的交换机符合开放系统互连模型第二层协议,并作为快速网桥工作,这意味着它们对网络层协议是透明的。
Since layer 2 switching is performed at the open systems interconnection data link layer , it is faster than routing or layer 3 ( network layer ) switching , which must open ip packets to determine destinations 由于第二层交换是在开放系统互连模型的数据链路层中进行的,所以它比路由或第3层(网络层)交换速度要快,因为该交换必须打开ip包来确定目的地。
