Research on survivability in multi-service-based multi-domain optical networks

Focused all the attention on survivability schemes under the high speed, multi-service and integrated multi-domain optical networks (MDON) environment. In this paper, based on the traits which are multi-service and distributed control for optical network, we first analyze the problems and challenges posed by MDON survivability. According to the survivability need of MDON, we classify associated key issues, and discuss some core techniques; moreover, the direction for future research work is indicated.
