| Abstract: | The integration of different technologies such as ATM over SDH multilayer transport networks raises many questions regarding the coordination of the individual network layers. In particular, in the area of network survivability, much can be gained by a better alignment of the healing actions taken by different network layers in case of outages. A new self-healing scheme with a new architecture and a new routing algorithm is proposed. Simulation shows that the scheme can achieve quicker restoration than other schemes proposed. |
