Abstract
Abstract In this paper, a (network-service value)-based admission decision mechanism for ONU’s virtual access under distributed control in virtual passive optical network (VPON) is proposed. By introducing distributed control into VPON, a more efficient VPON architecture is proposed. By designing corresponding information flow, the virtual connections between ONU and OLT can be constructed. By proposing a comprehensive weight ratio allocation (CWRA) algorithm, an admission decision mechanism is constructed. By this mechanism, the load and bandwidth allocation of VPON can be adjusted. By simulation, the effectiveness of the proposed mechanism is demonstrated.
