英文摘要：

ION is the evolution direction for the next-generation optical network while a rapid and efficient survivability strategy is the ION＇s premier characteristics. The GMPLS-based protection and restoration mechanisms for ION are studied in this paper. A GMPLS-based survivability scheme of control plane is discussed on the basis of the comparison of different kinds of survivability algorithms. A new method dealing with node failure is presented. The restoration time of GMPLS-based ION is analyzed finally.
