“…This is because the Adaptive scheme responses dynamically to the changes in the network status and attempts to explorer bigger solution space which may require using more network resources. This behavior is different from the one reported in [8] and [9] where the Adaptive approach had better utilization for the network resources. This is directly due to the constrained wavelength availability nature of the problem we tackle here.…”

“…The MILP formulation was extended in [8] to determine the exact number of OAs instead of the total amplification. We also proposed a heuristic approach in [8] and [9], called Optical amplifier Placement (OP) algorithm, to provide fast and efficient solutions by employing two schemes. The first scheme uses alternate routing for light-forest construction while the second scheme allows light-forest reconstruction.…”

Abstract-The connection provisioning problem attempts to achieve its objective of guaranteeing the maximum throughput and minimal blocking probability. In optical networks, this problem is mainly the classical Routing and Wavelength Assignment (RWA) problem, which includes many constraints. In this study, we investigate the RWA problem for connection provisioning under multicast traffic while considering the optical power constraints. The problem is first formulated as a MixedInteger Linear Program (MILP) with the objective of minimizing the session blocking rate. In order to provide fast and efficient solutions, the paper introduces a novel heuristic solution which divides the problem into subproblems and solves them separately, while still taking the interdependency between them into account. The results obtained from both solutions are found to be closely comparable. The results obtained from the heuristic also provide an insight for the network operators about the maximum performance enhancement that can be achieved by upgrading the network capacity.
