ABSTRACT:
A method and apparatus for mesh based protection of an optical network is described. A method comprises protecting a first set of one or more optical sub-channels with automatic protection switching, utilizing a second and third set of one or more optical sub-channels to transmit traffic in accordance with a mesh process to transmit traffic, and transmitting traffic in the third set of optical sub-channels, which would have been transmitted in the second set of optical sub-channels, in accordance with routes determined by the mesh process in response to an alarm indicating a failure affecting the second set of optical sub-channels.
