Energy-Efficient Frame-Buffer Architecture and It's Control Schemes for ONU Power Reduction

Energy Conservation in Passive Optical Networks: A Tutorial and Survey

“…The buffer size of an ONU can play an important role in the energy saving performance of the ONU. Uzawa et al in [271] measured that the downlink buffer of a 10G-EPON ONU accounts for 13% of the overall ONU energy consumption. They have introduced an ONU with dual-buffer-an internal and external buffer.…”

Multi-OLT and multi-wavelength PON-based open access network for improving the throughput and quality of services

“…Therefore, the number of buffers should be directly proportional to the number of service providers connected to an ONU. A buffer management unit (BMU) is also used to monitor and control the downstream data flow of a service provider to the designated buffer [22]. Fig.…”

“…In order to implement the principle that in the MM-OAN an ONU will be shared by the multiple service providers, modification of the conventional internal buffer architecture [21,22] in an ONU is required. That is why, in this paper, we propose a new internal buffer architecture for the proposed MM-OAN.…”
