Abstract:
In this research paper, we propose a novel
impairment-aware resource allocation scheme that increases
spectrum efficiency of an elastic optical network (EON), while
satisfying the quality of transmission (QoT) requirements of
traffic connections with different service priorities (i.e., high
and low priority traffic). To demonstrate the validity and
superiority of our algorithm, we compared the results of our
proposed resource allocation scheme against a benchmark
algorithm. The results were simulated for a 6-node network
and a 14-node network. Compared to the benchmark
algorithm, on average, our proposed scheme increases
spectrum efficiency by an additional 20 % while ensuring a
minimum latency for high priority traffic, causing minimum
disruptions to existing low priority traffic, and blocking less
than 1 % of the total connections.
