On the basis of analyzing the existing performance evaluation program for the advantages and disadvantages of switch, a evaluation method that can evaluate the switch performance in smart grid based on AHP-Entropy method and fuzzy-comprehensive evaluation theory is presented, and automatic scoring to the switch is realized. The switch performance is analyzed from the aspects of the traffic, forwarding delay and addressing capacity by means of the fuzzy set theory. By employing the weight of AHP-Entropy method, the fuzzy comprehensive evaluation weight is calculated and then the comprehensive evaluation model of the switch is established. The calculation example shows that using above-mentioned index system and evaluation method can determine the impact of each index on the evaluation results and objectively evaluate the performance of the switch network,
