The application of network function virtualization (NFV) and software-defined networks (SDNs) to optical access systems continues to attract a lot of attention. Their use on general-purpose hardware allows for cost-effective implementation and quick response to functional requirements. This paper demonstrates the softwarization of the complete downstream physical (PHY)-layer functions of the optical line terminal (OLT), including a scrambler, which uses a serial processing algorithm that cannot be parallelized by a general-purpose graphics processing unit (GPU). We propose CPU-GPU cooperative implementation architecture that softwarizes the complete 10G-EPON OLT downstream PHY. We achieve 10.3125-Gbps real-time performance through experiments for the first time. |
