InthesamecontextofExercise4.7assumethataset ofSRGshasbeendefinedinthe network, and that a lightpath that is affected by a failure can change its route and wavelength. Devise the flow-path formulation which finds the routing and wavelength assignment of each lightpath in the no-failure state, and in each of the single-SRG
failure stages. The optimization target is minimizing the average propagation delay of the lightpaths. Implement a Net2Plan algorithm that solves this formulation with JOM and appropriately returns the optimum solution.
19. In the same context of Exercise 4.7 assume that a set F of SRGS has been defined in the network, and that a lightpath that is affected by a failure can change its route and wavelength. Devise the flow-path formulation which finds the routing and wavelength assignment of each lightpath de D in the no-failure state, and in each of the single-SRG failure stages. The optimization target is minimizing the average propagation delay of the lightpaths. Implement a Net2Plan algorithm that solves this formulation with JOM and appropriately returns the optimum solution.
