Abstract Time-division multiplexing passive optical network (TDM-PON) is referred to as a green network because it consumes minimum energy compared to the other access networks technologies. The optical network unit (ONU) mainly chooses to adjust energy-saving in TDM-PON by turning off its receiver and/or transmitter for the substantial time that is called doze or sleep mode respectively. The main challenge in the TDM-PON energy-saving is finding acceptable sleep/doze duration time to achieve energy-saving and guarantee the quality of service (QoS). This paper proposes a mathematical model built based on the lattice theory, which is applied to the results of the fixed-point theory. In the domain of nonlinear systems, each monotone function on a chosen complete lattice has a fixed point, and this point can be interpreted as the solution of the system. The output of the mathematical model is the sleep/doze duration domain that satisfies all requirements and guarantees the QoS metrics. The mathematical model is adopted with doze mode conditions to evaluate the system. Simulation results approve our model that achieves energy-saving up to 63% while keeping the QoS parameters in the acceptable boundary.

基于点阵的EPON节能方案分析

摘要 时分复用无源光网络（TDM-PON）被称为绿色网络，因为与其他接入网络技术相比，它消耗的能量最少。光网络单元（ONU）在TDM-PON中主要选择通过关闭其接收器和/或发射器一段相当长的时间来调整节能，分别称为打盹或睡眠模式。TDM-PON节能的主要挑战是找到可接受的睡眠/打盹持续时间以实现节能并保证服务质量（QoS）。本文提出了一种基于格理论建立的数学模型，并将其应用于不动点理论的结果。在非线性系统域中，选定的完整点阵上的每个单调函数都有一个不动点，而这一点可以解释为系统的解。数学模型的输出是满足所有要求并保证 QoS 指标的睡眠/打瞌睡持续时间域。该数学模型采用休眠模式条件对系统进行评估。仿真结果证实了我们的模型，在将 QoS 参数保持在可接受的边界内的同时，实现了高达 63% 的节能。
