Abstract. We propose an evolutionary weighted model for technological networks based on the interplay of traffic and infrastructure of the network by introducing a strength cou-pling mechanism. The model gives many statical properties such as evolution of strength, distribution of strength, degree and weight supported by empirical evidence. In particular, the model generates nontrivial degree-strength correlation observed in real-world networks. Interestingly, all properties are adjusted depending on a single parameter that represents the speed of total weight growth of the network
