An upcoming capable technology named as Next generation Ethernet passive optical network (NG-EPON); to handle enormous bandwidth and effective distribution requirements for prospective Internet based services. Standardization procedures for NG-EPON are in progress. Transmission of data traffic from Optical Network Units (ONUs) towards Optical Line Terminal (OLT) in NG-EPON is carried out through four wavelengths each operating at a data rate of 25Gbps. Dynamic wavelength and bandwidth allocation (DWBA) algorithms are needed for the efficient arbitration of the bandwidth resources between the subscribers. In this paper, we have proposed two different DWBA algorithms for NG-EPON; DWBA-I and DWBA-II. DWBA-I is a Quality-of-Service based algorithm that has been designed to manage the different types of data traffic in NG-EPON. DWBA-I performs better than the different existing DBA algorithms in terms of packet delay, completion time and packet drop ratio. DWBA-II is an algorithm designed to meet the system requirement specifications of NG-EPON and handle traffic requirements of subscribers in a cost effective manner. DWBA-II algorithm is comparatively analyzed and evaluated with First-Fit-DWBA and Modified-IPACT algorithms. Performance of DWBA-II is better on the basis of average delay, grant utilization, completion time and packets drop ratio. Performance of DWBA-I and DWBA-II has been evaluated through simulation results.

NG-EPON 的带宽利用和管理算法 (BUMA)

即将推出的名为下一代以太网无源光网络 (NG-EPON) 的技术;处理潜在的基于 Internet 的服务的巨大带宽和有效分发要求。NG-EPON 的标准化程序正在进行中。NG-EPON 中从光网络单元 (ONU) 到光线路终端 (OLT) 的数据流量传输通过四个波长执行,每个波长都以 25Gbps 的数据速率运行。需要动态波长和带宽分配 (DWBA) 算法来有效地仲裁用户之间的带宽资源。在本文中,我们为 NG-EPON 提出了两种不同的 DWBA 算法;DWBA-I 和 DWBA-II。DWBA-I 是一种基于服务质量的算法,旨在管理 NG-EPON 中不同类型的数据流量。DWBA-I 在数据包延迟、完成时间和丢包率方面的性能优于现有的不同 DBA 算法。DWBA-II 是一种算法,旨在满足 NG-EPON 的系统要求规范,并以具有成本效益的方式处理用户的流量要求。DWBA-II 算法与 First-Fit-DWBA 和 Modified-IPACT 算法进行了比较分析和评估。DWBA-II 在平均延迟、授权利用率、完成时间和丢包率的基础上的性能更好。DWBA-I 和 DWBA-II 的性能已通过仿真结果进行评估。DWBA-II 是一种算法,旨在满足 NG-EPON 的系统要求规范,并以具有成本效益的方式处理用户的流量要求。DWBA-II 算法与 First-Fit-DWBA 和 Modified-IPACT 算法进行了比较分析和评估。DWBA-II 在平均延迟、授权利用率、完成时间和丢包率的基础上的性能更好。DWBA-I 和 DWBA-II 的性能已通过仿真结果进行评估。DWBA-II 是一种算法,旨在满足 NG-EPON 的系统要求规范,并以具有成本效益的方式处理用户的流量要求。DWBA-II 算法与 First-Fit-DWBA 和 Modified-IPACT 算法进行了比较分析和评估。DWBA-II 在平均延迟、授权利用率、完成时间和丢包率的基础上的性能更好。DWBA-I 和 DWBA-II 的性能已通过仿真结果进行评估。
