Designing a green optical network unit using ARMA-based traffic prediction

Design of Energy-Efficient EPON: A Novel Protocol Proposal and Its Performance Analysis

“…All simulations are performed in OMNET++ for a network runtime of 50s and the results are plotted with 95% confidence interval. The link rate of the feeder fiber, the maximum traffic arrival rate at each ONU, the packet size and T m are assumed to be 1Gbps, 100M bps, 1500Bytes and 0.5ms respectively [16]. Sleep-to-wake-up time of ds, f s, and dz are considered to be 5.125ms, 125µs and 1µs respectively [16].…”

“…The performance analysis of this sleep mode has been proposed in [18]. The major drawback of all OLT-assisted protocols is that they require changing the MAC of both OLT and ONUs [16]. Thus, a prodigious amount of expenditure is required to employ an OLT-assisted protocol in a legacy network [16].…”

“…However, it is well known that the power consumption figure of doze mode is quite high [3]. In [16], [20], we have proposed a novel protocol where ONUs dynamically swerve between the active mode and different low power modes where ONUs select the most suitable low power mode based on the sleep duration (time interval over which low power mode is employed) before entering into a low power mode. Once an ONU enters into a low power mode, a certain time interval is required to wake-up from the low power mode and to initiate the US [2] transmission.…”
