Resource Management in Stargate-Based Ethernet Passive Optical Networks (SG-EPONs)

At present there is a strong worldwide push towards bringing fiber closer to individual homes and businesses. Another evolutionary step is the cost-effective all-optical integration of fiber-based access and metro networks. STARGATE [1] is an all- optical access-metro architecture which does not rely on costly active devices and makes use of an overlay island of transparency with optical bypassing capabilities. In this paper we propose ONU architectures, and discuss several technical challenges, which allow STARGATE EPONs (SG-EPONs) to evolve in a pay-as-you grow manner while providing backward compatibility with legacy infrastructure and protecting previous investment. Using a simple bandwidth and wavelength allocation, we study the capacity and delay performance of SG-EPON through simulations.
