简介
The application of network function virtualization (NFV) and software defined networks (SDNs) to optical access systems is attracting attention in order to quickly and cost-effectively respond to various service requests. In order to maximize the merits of NFV/SDN, we aim at expanding the software-defined region of optical line terminals (OLTs) by focusing on physical-layer (PHY) functions for the flexible access system architecture. We have studied 10-Gb/s software implementation of OLT PHY functions using general-purpose graphic processing units since they offer large computation resources. However, burst-frame synchronization, which is essential for upstream PHY, is the lowest function of OLT and is very difficult to process in software due to its high computational complexity. This paper proposes a bitshift implementation method using array access for our dual-stage detection algorithm. By accessing the data …
