通信网络的能耗对环境稳定性构成了相当大的威胁。接入网络的扩展构成了互联网回程的主要游乐场，伴随着许多能源效率低下的设备和装置。无源光网络（脑桥）是接入网领域的潜在主导技术，因此降低光器件的能耗成为一个关键问题。在本文中，介绍了一种高效的绿色PON，具有两个主要目标：a）通过允许光设备在睡眠模式下操作更长时间来降低能量消耗，以及B）保持PON的良好性能。除了绿色配置，该方案是能够偶尔增加网络的平均分组延迟和丢包率方面的性能。这是通过减少在睡眠模式下操作的用户与中心局之间的控制消息量来实现的，从而允许分配更多的带宽用于数据传送。
Communication networks' energy consumption poses a considerable threat to the environment stability. The expansion of access networks, which constitute the main playground of the Internet backhaul, is accompanied by numerous energy inefficient devices and equipments. Passive optical networks (PONs) is a potential dominant technology on the field of access networking, hence the reduction of the consumed energy of the optical devices forms a critical issue. In this paper, an efficient green PON is introduced, having two main targets: a) to reduce the energy consumption, by allowing optical devices to operate longer in sleep mode, and b) to maintain PON's good performance. Beyond the green provisioning, the proposed scheme is able to increase occasionally the network performance in terms of mean packet delay and packet drop ratio. This is accomplished by reducing the amount of control messages between subscribers, operating in sleep mode, and central office, allowing more bandwidth to be allocated for data delivering.
