Network Coding in Next-Generation Passive Optical Networks

As the emerging access architecture, NGPONs feature enhanced PON configurations, metro-access integration, and bimodal Fiber-Wireless (FiWi) networks. The moving landscape of NG-PONs provides opportunities for applying novel and promising technologies such as Network Coding (NC). In this paper, the authors introduce the basic principles of NC and discuss their applicability to NG-PONs, with a focus on layer 2 design. Their example illustrations and simulations demonstrate significant potential performance improvements in various NG-PON scenarios while clarifying some underlying topological constraints of NC.
