Title: Energy Efficient Next Generation Passive Optical Network for Sustainable Green Communication Network Infrastructure

Abstract: The issue of power consumption in ICT sector is becoming serious day by day due to the massive expansion of ICT sector especially telecommunication networks. This sector is consuming significant power that is not only causing increased network maintenance costs but also deteriorating our planet environment by emitting Green House Gases (GHG) like carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) due to 10% consumption of the global electricity generation. Specifically, access network has been reported to consume 70% of it. Although as compared to the legacy copper based access network, the optical fiber based access networks are greener and energy efficient but still the power consumption of these access networks is significant and needs the attention of the research community. Therefore in this talk, I will reviewed all the proposed techniques to reduce power consumption of a GPON network especially focusing on the non-disruptive techniques, which requiring only firmware changes in the ONU and OLT. It has been reported that up to 97-99% frames are processed and then discarded by an ONU for being unrelated. This also leads ONUs to continuously remain fully active and thus consuming up to 60% of the whole PON power. Therefore, efficient energy conservation techniques are required at ONU to reduce its power consumption. Compared to physical layer based techniques, MAC layer based energy conservation techniques are more suitable as they do not require new investment and can be adapted in the currently deployed network, as well as in future architectures. Hence, the shortcomings in present MAC layer of ITU PONs and the proposed novel energy efficient schemes to make the PON more sustainable as ‘green access network’ will be presented.
