| Abstract: | The paper presents the method to complete network switch in chip of network controller in allusion to network switch delay in the redundancy backup technology of the network cards in the network communications. The network channels is switched according to the state of network channels working and data receiving circuit when datum received are decoded in network link layer. This implements the function of real-time switch when network equipment is trouble in physics layer or datum received is wrong. |
