抄録
<p>In order to meet the diversifying demands, we propose the architecture of the software-based virtual EPON-OLT, where all of OLT functions except PHY-Layer are implemented as software running on an x86 server. The EPON-OLT requires not only high throughput, low latency but also accurate controls for the upstream transmission timing of ONUs. In order to satisfy these conditions, we introduced two methods for the virtual OLT: (1) Separation of D-Plane/C-Plane and (2) Smoothing RTT. Evaluation experiments show wire-speed throughput and low latency are achieved when the packet length is short, but simultaneously, a technical issue with long packet transmission.</p>
