The Effect of Frequency Slot Demand in Elastic Optical Network (EON)

Impairment‐aware resource allocation scheme for elastic optical networks with different service priorities

“…Emerging services such as virtual and augmented reality applications, remote medical procedures, 5G and 6G mobile networks, smart power grids, smart metering systems, and distributed automated systems impose new demands on communication infrastructure [1][2][3][4][5][6][7]. These services not only require uninterrupted fast network connectivity but also require a super quality of service (QoS) and low latency [2,8].…”

“…IP-over-wavelength division multiplexing (WDM) networks) may soon exhaust the available spectrum resources in optical networks [7,[10][11][12]. Hence, elastic optical networks (EONs) are widely accepted to be the key enabling technology of future high-capacity and high-bandwidth internet [1,7,[13][14][15][16][17].…”

Simulation Studies of 3-Stage Clos Switching Network with Prioritization Mechanism Used in Flexible Wavelength-Division Multiplexing Network Nodes

“…Assigning bandwidth to a data stream flexibly is achieved by utilizing a defined quantity of consecutive FSUs [3][4][5][6][7]. Research on frequency slots in the flexible WDM networks is presented in [8,9], among others. In the work [8], two slot selection algorithms are discussed and their efficiency is compared.…”

“…In the work [8], two slot selection algorithms are discussed and their efficiency is compared. The work [9], on the other hand, presents a study of the effect of the size of requests expressed in slots on the performance of a network described by different quality assessment parameters. It is worth noting that other factors affecting the number of frequency units (FSUs) allocated can also be distinguished, which include modulation technique, distance, and connection path quality [10][11][12][13][14][15].…”
