Abstract :
To achieve higher resource utilization in IP/WDM networks, this paper develops an approach called hop-constraint lightpath establishment approach (HCLEA) to improve existing routing algorithms. HCLEA prevents the routing algorithm from creating long lightpaths with low efficiency. Simulation results show that HCLEA can achieve a significant improvement in terms of resource utilization and bandwidth blocking ratio.
