In the solution of network designing, this article presents a reliable and secure network based network Switch, network balance, and network redundancy.

Through analyzing the power flow in a switch network, a calculation method and formula and its program block diagram of conductance ratio of every switch are put forward in this paper.

The task of this research is to design a high speed data switch network which is used in a base station controller (BSC) of a digital mobile communication system based on CDMA technique.
