摘要
正交频分复用无源光网络(OFDM-PON，orthogonal frequency division multiplexing passive optical network)具有带宽容量大、资源分配灵活等优势，被公认为下一代光接入网的重要候选技术之一。目前，OFDM-PON 系统结构的相关研究层出不穷，然而这些研究大多专注于物理结构和信号传输技术，缺少与新型系统结构相适应的带宽分配算法。OFDM-PON 中带宽分配涉及时域、频域、比特等多维资源的联合优化，是保证多业务接入和服务质量的关键技术。针对 OFDM-PON 的增强型系统结构，提出多业务分层带宽分配算法，以实现增强型OFDM-PON系统带宽资源的高效利用。仿真结果表明，相比传统OFDM-PON系统中无分层带宽分配算法，增强型OFDM-PON的分层带宽分配算法在带宽资源利用率和数据分组时延等性能方面具有明显优势。
Abstract
Due to the superiority in large bandwidth capacity and flexible resource allocation
orthogonal frequency division multiplexing passive optical network (OFDM-PON) has been recognized as one of the promising candidates for the next generation PON.There are many research works on the system architecture design of OFDM-PON.However
most of these works focused on the techniques of physical structure and signal transmission and less addressed the bandwidth allocation algorithms supporting the new types of system architecture.The bandwidth allocation in OFDM-PON
which is one of the key techniques to enable the access of multi-service
refers to the joint optimization of multi-dimensional resources in time domain
frequency domain and bits.A layered bandwidth allocation algorithm was proposed for multi-service in the enhanced system architecture of OFDM-PON
aiming at the efficient bandwidth resource utilization.Simulation results prove that the proposed bandwidth allocation algorithm outperforms the conventional algorithms without layered transmission significantly in terms of resource utilization and packet delay.
