We demonstrate for the first time computation of both single and disjoint regenerated paths using all-optical reachability matrix and hierarchical guided search, scaling to optical networks with thousands of nodes.
In this paper, we aim to minimize the total network cost in flexible-grid optical networks with multiple line rates. Besides transponder cost, regenerator cost, and shared infrastructure cost, the cost of regenerator sites is also considered. We first provide the problem definition and formulate the problem as an integer linear program (ILP). We also propose a heuristic algorithm considering both...
We evaluate contiguous, discrete and hybrid slot assignment methods under both quasi-static and dynamic traffic conditions. We show the tradeoff among these methods in terms of network performance and system complexity.
We use Monte Carlo simulations of quasi-static traffic growth to study concentration of regenerator sites in dynamic photonic networks supporting service velocity. Idle regenerators can be reduced by >60% compared to unrestricted regeneration sites.
