Adaptive methods allocate spectrum to optimize efficiency in multiband optical networks, suggesting improved performance outcomes.
Key Points
This research aims to enhance the efficiency of spectrum allocation in multiband elastic optical networks by integrating bit rate and path length considerations.
Proposed three adaptive spectrum allocation strategies: BR-SAS, PL-SAS, and BR + PL-SAS.
Dynamically select allocation sequences based on incoming request characteristics.
Conducted extensive simulations on NSFNET and USNET topologies to evaluate performance.
BR + PL-SAS achieved the lowest request blocking probability (RBP) across both topologies.
BR-SAS demonstrated moderate performance in RBP and fairness.
PL-SAS offered the highest fairness but had the highest RBP, indicating lower provisioning efficiency.
