Networks are frequently changing due to new technologies. The growing demand for bandwidth is forcing many carriers to migrate their existing network to a network with a new technology in order to increase network performance. Telecommunication companies are looking for optimization algorithms to efficiently manage their network migration. In this paper, the network migration problem is considered as a set of circuit migration problems in which two technicians simultaneously migrate the two ends of a circuit in order to minimize the total accumulated sites in-service and total technician travels. While total accumulated sites in-service indicates how fast the sites can be upgraded during the migration process, total technician travels estimates the required cost. We first formulate our target problem as a constrained binary quadratic program which is NP-hard in general. Our approach for solving the derived optimization problem is based on converting it to a quadratic unconstrained binary optimization problem (QUBO) using the penalty method. Subsequently, we exploit Digital Annealer which is a massively parallel hardware architecture to minimize the derived QUBO. To evaluate our proposed method, we study extensive network migration instances on the 75-node CONUS network topology.

Current fixed grid DWDM netw to be insufficient to accommodate expected dem Hence, operators need to compare different al with future demands. This paper presents a ste economic methodology to compare and id convenient upgrade alternative(s). One of the p scenarios is towards flexible grid optical comparative evaluation is made in terms of operational expenditures considering the cost pe The proposed methodology is applied to an op initial scenario a statically operated network u with connections at 10 Gbps. Three d alternatives are evaluated: (i) static operation u is maintained but the bit rate of connections is Gbps; (ii) the network is operated dynam established/released on demand) in a fixed gr connections and finally, (iii) a dynamic netwo flexible grid. Results for this particular case, sh operation with flexible grid is not the most con alternative, given the high cost of the required e This methodology is expected to be useful for n evaluating different upgrade alternatives for th and manufacturers aiming to evaluate the p equipment.Index Terms-Total cost ownership, flex networks.
