Input Buffer in Dynamic Elastic Optical Networks

This paper explores the implementation of a buffer allocation strategy within Elastic Optical Networks (EONs) to manage connection requests that cannot be immediately allocated. The proposed strategy was evaluated using NSFNet and EuroCore topologies, employing RSA and RMSA algorithms. The results demonstrated a significant reduction in blocking probability with the application of the buffer, especially in lower traffic loads. Nevertheless, this approach led to quality of service challenges and introduced a head-of-line blocking issue. The paper discusses future research directions focusing on achieving a balanced trade-off and exploring multiband contexts.
