Abstract

Optical fiber access systems are one of the driving forces behind the success of the Internet. Time- and wavelength-division multiplexing passive optical network (TWDM-PON) is regarded as the key technology for future Internet access networks. In this paper, we propose an ITU TWDM-PON module for the ns-3 network simulator and describe its concept and design specifications. The proposed module is developed based on the XG-PON module for ns-3. It can simulate G.989 standard-compliant data packet transmission in the upstream and downstream directions using multiple wavelength channels. It enables us to evaluate the performance issues that arise with the TWDM-PON development, including various dynamic bandwidth allocation and dynamic wavelength allocation algorithms. The proposed module is expected to become a good platform for studying future access networks composed of TWDM-PON and mobile networks by enabling us to simulate dynamic wavelength and bandwidth allocation.

ns-3的ITU TWDM-PON模块

摘要

光纤接入系统是互联网成功背后的推动力之一。时分和波分复用无源光网络（TWDM-PON）被视为未来Internet接入网络的关键技术。在本文中，我们为ns-3网络模拟器提出了ITU TWDM-PON模块，并描述了其概念和设计规范。所建议的模块是基于ns-3的XG-PON模块开发的。它可以使用多个波长通道在上行和下行方向上模拟符合G.989标准的数据包传输。它使我们能够评估TWDM-PON开发中出现的性能问题，包括各种动态带宽分配和动态波长分配算法。
