下一代无源光网络（NG-PONs）扩展版的容量和时延分析
Capacity and Delay Analysis of Next-Generation Passive Optical Networks (NG-PONs) - Extended Version
摘要：
基于以太网无源光网络（EPON）和千兆位PON（GPON）标准，下一代（NG）PON（i）提供增加的数据率、分流比、波长计数和光纤长度，以及（ii）允许接入和城域网的全光集成。在本文中，我们提供了一个全面的概率分析的能力（最大平均分组吞吐量）和分组延迟的子网，可用于形成NG-PON。我们的分析可以涵盖广泛的NG-PON通过采取的最小容量的子网络组成的NG-PON和加权的分组延迟的子网络。我们的数值和模拟结果表明，我们的分析相当准确地表征了EPON/GPON树型网络的吞吐量延迟性能，包括网络升级与更高的数据率和波长计数。我们的分析还描述了在城域范围内集成EPON/GPON树型网络时的权衡和瓶颈，其中包括环形、无源星形耦合器（PSC）或阵列波导光栅（AWG），以实现均匀和非均匀流量。据我们所知，所提出的分析是第一次考虑多个PON通过城域网互连。
英文摘要：
Building on the Ethernet Passive Optical Network (EPON) and Gigabit PON (GPON) standards, Next-Generation (NG) PONs (i) provide increased data rates, split ratios, wavelengths counts, and fiber lengths, as well as (ii) allow for all-optical integration of access and metro networks. In this paper we provide a comprehensive probabilistic analysis of the capacity (maximum mean packet throughput) and packet delay of subnetworks that can be used to form NG-PONs. Our analysis can cover a wide range of NG-PONs through taking the minimum capacity of the subnetworks making up the NG-PON and weighing the packet delays of the subnetworks. Our numerical and simulation results indicate that our analysis quite accurately characterizes the throughput-delay performance of EPON/GPON tree networks, including networks upgraded with higher data rates and wavelength counts. Our analysis also characterizes the trade-offs and bottlenecks when integrating EPON/GPON tree networks across a metro area with a ring, a Passive Star Coupler (PSC), or an Arrayed Waveguide Grating (AWG) for uniform and non-uniform traffic. To the best of our knowledge, the presented analysis is the first to consider multiple PONs interconnected via a metro network.
