We propose a methodology for planning TWDM-PON that combines three lines of approach, known from literature, into a single approach that establishes a trade-off among them. That may support the network designer in finding a solution that can, simultaneously, meet high bandwidth demands, keep assurance of quality of service (QoS) level agreed with users, and increase energy saving of the network by taking into account the users’ activity and bandwidth sharing in the network. To develop the proposed algorithm, two bandwidth management techniques have been analyzed aiming at a possible migration of the end user equipment (optical network unit, ONU), whereas possible, in a more efficient distribution of ONU per wavelength pair (downstream-upstream). As a result, it becomes possible to switch off some management interfaces, thus assuring a degree of energy save. In parallel, two methods for providing an adaptive record of ONUs were aggregated to improve the performance of those ONUs that are migrating and/or entering the network, thus avoiding collision between signals and increasing the chance of their registration in the optical line terminal (OLT). The paper also addresses the fulfillment of the service level agreement (SLA), signed by operators and users, and proposes ways for designing a TWDM-PON that offers services with a quality metric assurance. Different scenarios with variable percentage of active users were considered and it was noticed that, in more realistic scenarios (50%, in average, of active ONUs), the network saved almost 50% of energy at the interfaces to be configured, with a migration period around 5 min. Additionally, it reached a SLA close to 100%, which is above the usual when it comes to compliance services. In addition, to meet bandwidth demand up to 1 Gb/s, the QoS was evaluated in four common Split Ratios (1:8 to 1:64) that the TWDM-PON can be configured, from the simplest to the most complex scenarios (active user, p, from 10% to 100%). In this way, it was verified that for the network to comply with satisfactory QoS, minimum percentage of time during which the target bit rate should be available for each connected user, the TWDM-PON should be planned at different activity levels, and the best planning are (p = 100%, 1:8), (p = 70%, 1:16), (p = 40%, 1:32) and (p = 20%, 1:64).

我们提出了一种规划TWDM-PON的方法，该方法将文献中已知的三类方法结合到一个可以在两者之间进行权衡的单一方法中。这可以支持网络设计人员找到一种解决方案，该解决方案可以同时满足高带宽需求，确保与用户达成一致的服务质量（QoS）级别保证，并通过考虑用户的活动和网络中的带宽共享。为了开发提出的算法，针对最终用户设备（光网络单元，ONU）的可能迁移，已经分析了两种带宽管理技术，而有可能以每个波长对（下游-上行）更有效地分配ONU。结果，可以关闭某些管理界面，从而确保一定程度的节能。同时，聚合了两种提供ONU自适应记录的方法，以提高正在迁移和/或进入网络的ONU的性能，从而避免了信号之间的冲突并增加了它们在光线路终端（OLT）中注册的机会。 ）。本文还讨论了由运营商和用户签署的服务水平协议（SLA）的实现，并提出了设计TWDM-PON的方法，该TWDM-PON提供了具有质量度量保证的服务。考虑了具有不同活动用户百分比的不同方案，并且注意到，在更实际的方案（平均50％的活动ONU）中，通过迁移，网络可以节省将近50％的能量在要配置的接口上5分钟左右。另外，它达到了接近100％的SLA，高于合规服务方面的通常水平。此外，为了满足高达1 Gb / s的带宽需求，从最简单到最复杂的情​​况下，都可以配置TWDM-PON的四种常见分离率（1：8至1:64）评估QoS（活动用户，p，从10％到100％）。通过这种方式，已验证，要使网络符合令人满意的QoS，应为每个连接的用户提供目标比特率的最小时间百分比，应该在不同的活动级别计划TWDM-PON，并且最好规划是（p  = 100 ％，1：8），（p  = 70 ％，1:16），（p  = 40 ％，1:32）和（p  = 20 ％，1:64）。
