软件定义网络(SDN)已发展成为一种方法，允许网络管理员对OSI模型的网络组件(主要在L2-L3层)进行编程和初始化、控制、更改和管理。SDN旨在解决云数据中心(CDC)中常用的传统网络架构的可编程性缺陷。SDN解决方案的部署在CDC的流量优化和带宽分配等领域取得了显著改善。然而，在通过将多个CDC联网来交付解决方案的环境中考虑软件定义的广域网(SD-WAN)架构时，对这些优势的探讨要少得多。为了支持对依赖于跨多个云数据中心的数据接收和处理(例如，智能能源云、内容交付网络)的数据驱动的应用程序进行测试和基准测试，本文提出了模拟器IoTSim-SDWAN。据我们所知，IoTSim-SDWAN是第一个在SD-广域网生态系统和支持SDN的多个云数据中心的环境中简化新算法、策略和设计的建模、模拟和评估的模拟器。最后，对IoTSim-SD广域网络模拟器的网络性能和能量进行了评估，以说明传统广域网和SD-广域网环境的不同。结果表明，SD-广域网在加速流量和降低功耗方面均优于传统广域网。(C)2020 Elsevier Inc.保留所有权利。
Software-defined networking (SDN) has evolved as an approach that allows network administrators to program and initialize, control, change and manage networking components (mostly at L2-L3 layers) of the OSI model. SDN is designed to address the programmability shortcomings of traditional networking architectures commonly used in cloud datacenters (CDC). Deployment of SDN solutions have demonstrated significant improvements in areas such as flow optimization and bandwidth allocation in a CDC. However, the benefits are significantly less explored when considering Software-Defined Wide Area Networks (SD-WAN) architectures in the context of delivering solutions by networking multiple CDCs. To support the testing and bench-marking of data-driven applications that rely on data ingestion and processing (e.g., Smart Energy Cloud, Content Delivery Networks) across multiple cloud datacenters, this paper presents the simulator, IoTSim-SDWAN. To the best of our knowledge, IoTSim-SDWAN is the first simulator that facilitates the modeling, simulating, and evaluating of new algorithms, policies, and designs in the context of SD-WAN ecosystems and SDN-enabled multiple cloud datacenters. Finally, IoTSim-SDWAN simulator is evaluated for network performance and energy to illustrate the difference between classical WAN and SD-WAN environments. The obtained results show that SD-WAN surpasses the classical WAN in terms of accelerating traffic flows and reducing power consumption. (C) 2020 Elsevier Inc. All rights reserved.
