Abstract :
We propose a global dynamic bandwidth optimization algorithm for software defined optical access and aggregation networks, which can support unified optimizations and efficient scheduling by allocating bandwidth resources from a global network view in real-time. The performance benefits of the proposed algorithm in terms of resource utilization rate, average delay and delay of a single mobile user are verified through network simulation.
