A Reliable Fuzzy Routing Method to Enhance Quality of Service in Software-Defined Networks

The rapid expansion of networks, including the Internet, intranets, and local areanetworks, has led to a significant increase in their management complexity in recentyears. This complexity spans both software and hardware layers, presenting numerouschallenges for network administrators. Simplifying configurations and lowering costsare key concerns for network developers. Intelligent networking and virtualizationrepresent prominent techniques being pursued to address these challenges. Trafficengineering plays a crucial role in analyzing data transmission and routing packetsoptimally to enhance overall network performance, including reducing delays and improvingpacket delivery rates. In the proposed approach, we aim to enhance reliability,a critical Quality of Service factor for SDN-enabled networks. Consequently, we proposean efficient routing method based on fuzzy logic to minimize communicationdelay, to enhance fairness in traffic flow distribution, and to improve the success rateof data transmission. Simulation results indicate that our proposed method significantlyenhances network reliability, achieving approximately a ۳-۵% improvementacross defined metrics such as average delay, load distribution rates, and transmissionsuccess rates.
