GPON scheduling disciplines under multi-service bursty traffic and long-reach approach

摘要

Gigabit-capable PON (GPON) is the optical access standard being deployed by many incumbent operators, but the Dynamic Bandwidth Allocation (DBA) algorithm for multi-service Quality of Service (QoS) is not specified; hence, to provide QoS we propose fair DBA scheduling disciplines adapted to bursty traffic. Moreover, Long-Reach (LR) access is a promising scheme for future next generation access networks, enabling for a large number of customers in the access/metro area. We improve our scheduling disciplines to enhance the transmission efficiency in the LR approach by using a traffic prediction.
