In the paper, the foundation requirement of a quantum key distribution network is described. According to the requirement, a kind of star topology quantum key distribution network is introduced. The core of this quantum network is a "router" which is composed of less than N wavelength division multiplexers. Based on the "router", a four nodes quantum key distribution network has been set up, the measurement results shown us that it is suitable for simple purpose of quantum key distribution over many users and the crosstalk is weak enough.
