The Survivability Strategies for Multilayered Transport Networks

With the developement of transport networks, it must face many new cha llenges for the increased network survivability. In this paper, we analyse the t rends of existent telecommunication transport networks. Taken into account the p roblems of network survivability, we focuse on the main problems in the multilay ered transport networks and propose the appropriate strategies and ideas.
