Overview

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.
