Applying Power Series Routing algorithm in transparent elastic optical networks

Abstract

In this paper, we propose two adaptations of the Power Series Routing (PSR) algorithm for transparent elastic optical networks: PSR algorithm with normalized distance and slot availability (PSRNDA) and PSR algorithm for normalized distance and slot contiguity (PSRNDC). In our analysis, we consider amplified spontaneous emission as physical impairment, different modulation formats and bit transmission rates, as well as losses on spectrum selective switch (SSS) devices. The results are obtained in terms of call blocking probability as a function of the network load. Comparing our proposed algorithms to several others present in the literature, our proposals overcame all of them.
