Abstract :
A flexible optical fiber code-division multiple-access (OCDMA) network is proposed to support multimedia services with different bit-rate and various quality-of-service (QoS) requirements. To achieve prioritization in OCDMA, the orthogonal-variable-spreading-factor (OVSF) code is utilized in this paper and a novel optimal configuration concept and scheme is involved to construct optical metropolitan area network (OMAN). Besides, it is appealed to apply a genetically modified genetic algorithm (GMGA) on optimal placement of the whole SD (source-destination) lightpaths in OMAN. Simulation results prove that genetic algorithms are efficient and robust for this problem
