A Novel VPON Scheme Syncretizing Multiple Subsystems for Metro-Access Optical Network

摘要

We propose a novel virtual passive optical network (VPON) scheme syncretizing multiple subsystems for metro-access optical network, which reflects the characteristic of flat network and meets the demand of technology compatibility. In this scheme, in order to maximize the utilization of finite network resource, the threshold-based resource recycling and allocation mechanism supporting the reconfiguration and escalation of VPON is proposed. Finally, we conduct detailed simulations to research and analyze the performance and demonstrate the effectiveness of the proposed scheme.
