Smart virtual wan hypervisor for environmental-aware inter-data network

随着互联网上不断增加的云计算应用的出现，基于wan的服务对信息和通信技术（ICT）行业的整体环境足迹做出了重大贡献。随着流量需求的增加和网络架构的异构化，广域网控制器也面临着互操作性、运行效率和服务质量的挑战。虽然在即将到来的全球限额和税收的推动下，环境意识正在成为广域网供应商的关键要求，但迄今为止，几乎没有任何环境意识的实验模型或实现用于广域网测试平台。因此，研究人员缺乏从整体上分析ICT碳足迹和绿色战略的资源。因此，该研究项目与Ciena、Inocybe Technologies和Prompt合作，旨在为下一代碳中性网络构建一种新型的能源感知智能虚拟WAN管理程序，该网络由绿星网络（GSN）模型演变而来，是世界上第一个实现基于“跟随风，跟随太阳”范式的绿色ICT倡议的测试平台。特别是，该项目将解决基于先进交通建模和认知算法的大型虚拟网络评估和绿化的新智能技术。新的环境感知分析模型将被开发出来，以帮助运营商规划、优化其长途网络，并使其货币化，而不会出现可能挑战财务可行性的过度供应。在软件定义网络（SDN）和网络功能虚拟化（NFV）技术的支持下，研究成果将为开发绿色虚拟数据中心间网络支持的一类新技术铺平道路，这是利用信息通信技术解决全球变暖问题的一步。这也将创造一个新的机会，利用加拿大丰富的可再生能源和较低的平均气温，特别适合冷却消耗大量能源的数据中心。

Along with the advent of the ever-increasing cloud computing applications on Internet, WAN-based services are contributing significantly to the overall environmental footprint of the Information and Communications Technologies (ICT) industry. With an increase in traffic demand and heterogeneity of network architecture, WAN controllers are also facing challenges of interoperation, operational efficiency and quality of service. While environmental awareness is becoming a key requirement for WAN network providers, driven by forthcoming global cap and tax, hardly any experimental models or realizations of environmental awareness exist for WAN testbed so far. As a result, researchers lack resources for analyzing the ICT carbon footprint and green strategies holistically. This research project, in partnership with Ciena, Inocybe Technologies, and Prompt is therefore, aimed at building a novel energy-aware smart virtual WAN hypervisor for a next-generation carbon-neutral network evolved from the GreenStar Network (GSN) model, the first testbed in the world that realizes a green ICT initiative based on the "follow the wind, follow the sun" paradigm. In particular, the project will address new smart techniques for assessing and greening large-scale virtual networks based on advanced traffic modeling and cognitive algorithms. New context-aware analytical models will be developed to help carriers planning, optimizing, and monetizing their long-haul networks without excessive over-provisioning that could challenge the financial viability. Research outcome, empowered by Software-Defined Networking (SDN) and Network Function Virtualization (NFV) techniques, will pave the way to develop a class of new technologies supported by green virtual inter- data centre networks, a step forward in addressing the global warming issue using the ICT sector. This will also create a new opportunity to take advantage of the abundance of renewable energy and low average temperatures in Canada that are particularly suitable for cooling data centres, which consume large amounts of energy.
