“…In the first context, namely, Network Provisioning, the problem is formulated as a network design problem with the objective of minimizing the network cost. In [1], we introduced a Mixed Integer Linear Program (MILP) that solves the Routing (R), Wavelength Assignment (WA) and Optical Amplifier Placement (OAP) subproblems in an integrated way for AOM traffic. The network cost in [1] is represented as the total power amplification needed in the network.…”

Abstract-The problem of placing the optical amplifiers (OAs) in wavelength-routing mesh networks has been studied in the literature in two contexts: network provisioning [1] and connections provisioning [2]. In this paper, we introduce optimal and heuristic solutions for the network provisioning problem. The solution is based on constructing a multicast forest for each multicast connection with the goal of minimizing the total number of OAs needed in the network, hence reducing its cost. The optimal solution is formulated as a Mixed Integer Linear Program (MILP). On the other hand, the heuristic solution is obtained by dividing the problem into subproblems and solving them separately while taking the interdependency between these subproblems into consideration. The results obtained from both solutions are compared and they are found to be in good match.

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.
