摘要

A method and apparatus for optimizing, in the presence of a failure, the availability of low-priority channels in a transmission fiber optic transoceanic MS-SP The method according to the present invention provides for selecting which of the low-priority channels can be maintained and which, on the contrary, are to be pre-empted for the benefit of the high-priority traffic. Advantageously, according to the present invention, all the traffic management operations are carried out simultaneously with the high-priority traffic switching.
