摘要：
In the metro-access optical network, a multi-channel scheduling algorithm is proposed for multi-subsystem-based virtual passive optical network (VPON) that can implement the syncretism of multiple systems such as time division multiplexing-PON (TDM-PON), wavelength division multiplexing-PON (WDM-PON), orthogonal frequency division multiplexing-PON (OFDM-PON) or their hybrid PON technologies. Through a module named adaptive transceiver, this algorithm can be directly applied in the metro segment with the reuse of original deployment in the access segment. The algorithm can be employed to schedule wavelength and subcarrier resource in WDM/TDM subsystems and WDM/OFDM subsystems respectively. Centralized management is used in the algorithm to facilitate channel scheduling and algorithm implementation. An optimal scheduling length is derived in the algorithm to realize the maximization of channel-utilized ratio. Two cases are investigated to demonstrate the effectiveness of the proposed algorithm in the channel-utilized ratio. (C) 2016 Elsevier B.V. All rights reserved.
