Description
Summary:With the development of passive optical network (PON), multiple PON systems using various multiplexing technologies can coexist. Virtualization technology is a preferable solution for multi-standard coexistence. In this paper, (max-min model)-based mode-matched algorithm is proposed in multisystem-based virtual passive optical network (VPON). By constructing a bipartite graph of the subsystems, a mode-matched graph is built. By introducing the concept of flow in mode-matched graph, max-min model is created. By the model, mode-matched algorithm is proposed. The maximum matching bandwidth and the minimum number of matching can be obtained by mode-matched algorithm. The utilization of network resources can be increased. Finally, the performance analyses and the simulations verify the effectiveness of the proposed algorithm.
