Keywords: Energy saving TDM-PONs Sleep mode Operator delay requirement TCP throughput a b s t r a c t Passive Optical Networks (PONs) are widely adopted as the last-mile technology due to the large bandwidth capacity it provides to end users. In addition, PON is viewed as a green access technology since it reduces energy consumption compared to other access(More)
—Due to the rapid growth of Internet and multimedia services, broadband fiber access technologies, such as Passive Optical Networks (PONs), come to the forefront of the research field. Network service providers mostly deploy Time Division Multiplexed (TDM)-PON everywhere in the world. In order to mitigate the future demand, researchers have investigated(More)
A ccess network equipment, such as that used in time-division multi-plexing passive optical networks (TDM-PONs), consumes around 70 percent of the overall telecom net work energy consumption, but its utilization is less than 15 percent. 1 Sleep mode is the most commonly u se d e ne r g y s av i ng pr i nc iple for TDM-PONs. Existing energy saving solutions(More)
Nowadays Passive Optical Network (PON) requires that Optical Network Units (ONUs) wake up periodically to check if the Optical Line Terminal (OLT) has any message directed to them. This implies that ONUs change from sleeping mode in which they just consume 1 W to active mode in which the consumption goes up to 10 W. In many cases, the OLT does not have any(More)
For more than a decade, the power consumption of data centers has been addressed from different perspectives. Many solutions have been proposed to reduce (or optimize) this power consumption, such as controlling the operation of the servers in data centers. However, these approaches have not yet reached their optimum goals. Existing power control solutions(More)
—In this paper, we propose a novel energy efficient solution for TDM Passive Optical Networks (TDM-PONs), which is a widely used access network technology, to facilitate local customer internetworking. Here, our prime objectives are to ensure traffic latency among different customers connected through TDM-PON and maximize energy saving performance of(More)
