Recently the robustness of coupled network under cascading failure has attracted a lot attention. In this paper, we investigate interconnected weighted networks based on state link. The load one link is defined by function strength two nodes at ends that link, using four intentional attack strategies, study invulnerability when occurs. Our studies show with highest attacked, damage to will be more serious attacking inner-link than caused coupling load, and no matter how links distribute, there are thresholds. addition, find larger weight increment in model or smaller network’s mean clustering coefficient, stronger ability resist while weaker suppress lowest attacked.
