A new asymmetric spectrum assignment method to improve spectrum efficiency for spectrum-sliced optical network

Abstract Bandwidth flexible optical network, referred to as spectrum-sliced elastic optical path network (SLICE), is a promising solution to achieve both high data rate transport and high spectrum-efficient. However, current methods to solve Routing and Spectrum Assignment (RSA) problems for SLICE network, conservatively accept the constraint that spectrum resources should be assigned symmetrically in both directions of one optical path. Since most data traffics are asymmetric by nature, the conventional way to simply aggregate them to form symmetric flows for transport layer is not as flexible as offering a direct asymmetric transport layer mechanism. In this paper, we present a novel Asymmetric Spectrum Assignment (ASA) method to future improve spectrum efficiency by saving redundant spectrum resources for the lighter load direction of one optical path to accommodate more incoming connection requests. We describe the concept of ASA and the enabling technologies to implement it. To compare the performance of proposed ASA with conventional Symmetric Spectrum Assignment (SSA), we classify the evaluations into four scenarios. We also observe the effect of various grid width values. Simulation result shows that: (i) ASA method always significantly outperforms the SSA method in any situation. (ii) Routing asymmetry is not necessary needed and spectrum assignment optimization takes obvious effect only under the situation of “random slot” grid width value.
