5G New Radio allows operators to use new and wider spectrum and complements Long-Term Evolution networks with higher data rates and lower latency. Supporting such requirements in the transport network is not only a technological challenge, but a financial one as well. The use of high-frequency or unlicensed spectrum and cell densification for capacity increases call for adoption of small cells. This means that the transport network needs to connect a large number of devices, which leads to high deployment costs. Improving resilience by redundancy would further inflate these cost. In this paper, we examine the prospect of enhancing resilience via an interleaved photonic transport network as well as by the cooperation of multiple operators. Resilience is quantified by the decrease in availability in case of a failure. Furthermore, we also investigate the case when the number of active cells is reduced not by failure, but due to deliberate switch-off in order to save power.

“…Recently, many works have proposed to improve the standards by optimization of the traffic flow and scheduling in the sleep mode [16][17][18][19][20][21][22][23][24]. In [19], an energy management mechanism is proposed to schedule two types of downstream schedule schemes, upstream centric scheme (UCS) and the downstream centric scheme (DCS), to maximize the sleep time and network performance.…”

“…If transmitter and receiver can be turned off independently without upstream traffic or downstream traffic, additional energy can be saved. A new energy-saving mechanism based on double-sleep-state and dynamic double-threshold receiver selection (EDDS) with the combination of 1G-EPON and 10G-EPON techniques is proposed in [22]. An energy-saving scheme based on downstream packet scheduling (ESPS) in EPON is proposed that a hybrid sleep mode contains not only ONU deep sleep mode but also independent sleep modes for the transmitter and the receiver to ensure that the energy consumed by the ONUs is minimal [23].…”

“…However, sleep duration is a critical value when realizing green TDM-PON as setting an overlong sleep duration can reduce the QoS, while short sleep duration increases the ONU power consumption [6]. Several ONU sleep-based techniques are proposed to adjust the sleep duration [19][20][21][22][23][24] based on just-in-time sleep control, fixed bandwidth allocation, downstream-centric scheme (DCS), upstreamcentric scheme (UCS), adaptive delay-aware energy efficient (ADAEE), and double-sleep-state and dynamic doublethreshold receiver selection (EDDS). Table 1 summarizes the abovementioned technique characteristics.…”

Ethernet passive optical network (EPON) is a broadband access time-division multiplexing passive optical network technology which can be referred to as green network, as it has less power consumption compared with other networks. The optical network unit (ONU) is the best candidate to implement energy-saving adjustments in EPON. Turning off the ONU transmitter (Tx)/receiver (Rx) for substantial time is a common method to achieve the energy saving. However, setting overlong sleep duration decreases the QoS, while short sleep duration increases the ONU power consumption. The challenging issue is how to balance the trade-off between achieving energy saving and guaranteeing QoS. In this paper, we introduce an enhanced EPON architecture and a QoS-aware energy-saving mechanism to reduce ONU energy consumption and guarantee an overall QoS metric based on the ITU-T standards requirements. To achieve the energy saving in the upstream/downstream direction, two sleep durations are defined for the ONU's Tx/Rx to generate four ONU modes including active, transmission, doze, and sleep. Simulation results show that the proposed scheme B I-Shyan Hwang improves the energy efficiency 44 % in average to fulfill the QoS metrics in terms of packet loss, delay and jitter, and the buffer requirement.
