它们成功的关键就在于使数据传输的软件开销减至最小，以及采用传输速度快且损耗小的光纤通信链。

The key of their success is that software overhead of data transmission is reduced to minimum and optical fiber communication chain with high speed transmission and low-dissipation is used.

该方案消除了TCP/IP协议栈的软件开销，也减少了核态与用户态的数据拷贝和上下文切换的开销。

The scheme removes the software overheads of TCP/IP protocols and reduces the overheads of context switching and data copying between the kernel and user levels.
