“…Moreover, their state transition probabilities are also not accurate and they did not take into account the inactivity of ONU in AS and SLA states. The results of this study also show the inaccuracy of this model as at no traffic load the maximum sojourn of ONU in AS state is only 35% which is not rational and contrast to the simulation results reported in other CSP studies such as references 12,20,21.…”

“…However, this study only considered the Active and AS states. An empirical model based on the queuing theory to configure the CSP has been presented in reference 12 using which the all the CSP parameters can be configured according to the desired average target US and DS delays. However, using this model the ONU sojourn in each state and the expected power consumption cannot be computed.…”

“…The CSP process comprises of four ONU power states; active‐held (AH), active‐free (AF), sleep‐aware (SLA), and asleep (AS). A detailed description of CSP may be referred in reference 12. The performance of CSP depends critically on the traffic arrival rate, configuration of the local wakeup indication (LWI) events and the ONU state timers.…”

For a network, a power consumption model is an important tool to test the performance of a network process for different traffic loads. In a Passive optical network (PON), the optical network unit (ONU) is responsible for the major power consumption of PON. Both IEEE and ITU have standardized a cyclic sleep process (CSP) for ONU energy conservation. In next-generation PON; TWDM and XGS PON, the ONU power contribution has increased further due to higher number of ONUs and ONU being tunable. Therefore, an accurate power consumption model of the CSP process for energy efficiency studies under different traffic conditions is of prime importance. The existing CSP power consumption models do not depict the CSP process accurately especially the inactivity of the ONU in the asleep and sleep aware states are not taken into account which reduce the accuracy of the model. The proposed inactivity aware model (IAM) overcomes these gaps and very accurately models the CSP process, as evident from the results, which are better than earlier model results and quite close to earlier published simulation results. The model is also validated through a simulation-based study and the simulation results are observed to be very close to the model results with only a 5% deviation.

“…According to Butt et al (2022), an accurate energy consumption model of the CSP operation is essential for analyzing energy efficiency in various traffic scenarios (Traffic aware cyclic sleep-based power consumption models for a passive optical network) [10]. The method is less accurate because it ignores the ONU's inactivity during the sleeping and sleep-conscious stages.…”

Energy proficiency is significant for optical organizations regarding versatility, minimal expense activity, and maintainability.Understanding energy with regards to optical organizations starts with a comprehension of the constituent parts and gear that make up an optical organization and how their energy use is advancing after some time. The organization design, depicting how these parts are assembled and worked, will likewise extensively affect the energy proficiency of optical organizations. Likewise, the level of security in optical organizations isn't been much explored in the research field. Thereby this paper brings an effective method for optimizing energy and also increasing security in an optical network using hybrid cloud computing techniques like heuristics optimization and FA algorithm. The author also carries a novelty in analysing and improving the security in optical networks using the Honeyspot algorithm. The results carried are shown a greater impact of the proposed system (EEFAHA-HONEYSPOT) over various measures

“…Findings in [10] impart that the utilization of access network equipment is only 15%. However, interestingly, the energy consumption footprint of access network equipment is approximately 70% of the overall energy demand of ICT [11], [12]. As the volume of data traffic grows due to increasing device use and bandwidth-intensive applications, access network energy consumption will only increase over time.…”
