XGPON Statistical Multiplexing Analysis with Heterogeneous Users

摘要

Optical access networks are rapidly evolving mainly driven by the higher bandwidth requirements. XGPON is one of the most cost-effective solutions to upgrade existing GPON since it reuses existing optical distribution networks. Thanks to the high XGPON capacity, these networks can connect heterogeneous users such as base stations (BS), residential users (RU) or business users (BU). Statistical multiplexing of XGPON allows assigning different bandwidth to the different users based on their demands and always guaranteeing the agreed service level agreements. This work aims at evaluating the impact of packet delay and throughput for different XGPON scenarios for different user distributions. Furthermore, the paper evaluates the flexibility to cope with extra traffic caused by existing protection schemes.
