Soft-Computing-Based Virtual Topology Design Methods in IP/DWDM Optical Internet

摘要

Virtual topology design is considered to be one of the key problems in the IP/DWDM optical Internet. Due to its NP-hard nature, with the objective of minimizing the sum of traffic-weighted hop count, two soft-computing-based methods to design the virtual topology are presented, adopting genetic algorithm and simulated annealing algorithm respectively. A simulation environment is developed and performance evaluations have also been done.
