Abstract

Abstract : The performance improvement imparted by routing and spectrum assignment on flexible grid optical networks is a subject of current extensive investigation. Proposed is an efficient spectrum‐assignment algorithm based on reducing the loss of capacity of future bandwidth‐variable path requests. In all scenarios analysed the proposed algorithm outperformed currently investigated slot assignment algorithms.
