1. A computer-implemented method for optical network evaluation, comprising:
- for a physical model, modeling propagation of a disturbance in an optical network under static network conditions based on the disturbance propagation having a threshold effect only on nodes along a route followed by the disturbance, the modeling implemented by a computer;
for a network model, modeling a status of each network route in the optical network based on the disturbance, the modeling implemented by the computer; and
combining the physical layer model and the network layer model to provide a cross layer model that characterizes the disturbance propagation based on network layer and physical layer dependencies and interactions in the optical network, the combining implemented by the computer, wherein modeling the status comprises determining a probability distribution of active connections in the optical network and the number of affected wavelength channels, the modeling implemented by the computer;
wherein all active wavelength channels in the switching plane of node Vi are affected if node Vi is affected by the disturbance, wherein
