摘要

软件定义网络（SDN）为管理采用不同制造商、技术和标准的设备的无源光网络（PON）提供了一个高效的框架。因此，我们最近提出了一种强大而灵活的 SDN-OpenFlow 代理，用于配置和管理万兆位对称无源光网络（XGS-PON），以支持互联网（数据）服务。该 SDN 代理通过 OpenFlow 协议与 SDN 控制器通信，并通过制造商芯片组特定的 API（应用编程接口）与 PON 的光线路终端 (OLT) 通信。在本文中，我们大幅扩展了 SDN 代理，为网络运营商和互联网服务提供商提供了支持两种基本服务的功能，特别是 IP 语音（VoIP）和视频服务。本文描述了组成 SDN 代理的不同层所需的扩展和配置程序，并在 XGS-PON 中对扩展 SDN 代理进行了实验验证，证明了它在集成这两种服务方面的有效性。SDN 代理的源代码已在 GitHub 上开放和提供。

Software-defined networking agent for integrating voice, data, and video services into XGS-PON architectures

Software-defined networking (SDN) provides an efficient framework for managing passive optical networks (PONs) with equipment from different manufacturers, technologies, and standards. Thus, we recently proposed a robust and flexible SDN-OpenFlow agent to configure and manage 10 gigabit symmetric passive optical networks (XGS-PONs) to support Internet (data) services. That SDN agent communicates with the SDN controller via the OpenFlow protocol and with the optical line terminal (OLT) of the PON via the manufacturer’s chipset-specific API (application programming interface). In this paper, we significantly extend that SDN agent by incorporating the capability to support two essential services for network operators and Internet service providers, specifically voice over IP (VoIP) and video services. The required extensions and configuration procedures on the different layers that compose the SDN agent are described, and an experimental validation of the extended SDN agent in an XGS-PON is conducted, demonstrating its effectiveness in the integration of those two services. The source code of the SDN agent has been made open and available on GitHub.

期刊介绍： The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
