The self-healing mechanism of ATM networks is one of the key techniques for ensuring the network survivability. Based on the consideration of the future development of ATM networks and the limitation of the former various algorithms, this paper proposed a new self-healing algorithm for ATM networks: back-routing self-healing back-routing self-healing. First, we show the basic principles about our scheme. Next, we give the concept of back-routing self-healing algorithm. Finally, we analyze the new mechanism and confirm the effectiveness and feasibility of the proposed scheme.
