任何网路层封包交换前，连结控制协定必须先开启连接并沟通彼此的组态参数。
Before any network layer packets can be exchanged, LCP must first open the connection and negotiate the configuration parameters.
因为连线是被分享，并且封包一定要被一个交换器完全地收到后才会移动到下一个交换器。
This is because the links are Shared and packets must be entirely received at one switch before moving to the next.
在这些网路中，资料以标记的细胞，讯框或封包中经过一个分封交换的网路被传输。
In these networks, the data is transmitted in labeled cells, frames, or packets through a packet - switched network.
因为针对每一个封包标头的IP地址进行转换，所以会带来一些交换路径的延迟。
Switching path delays are introduced because of the translation of each IP address within the packet headers.
如果快取项目存在时，剩馀的封包将会沿著快速交换的路径来传递。
The remaining packets will go through the fast-switched path if a cache entry exists.
