The remarkable growth in Internet traffic is expected to generate many new research challenges to address the new requirements in terms of volume and speed of exchanged data information. Indeed, telecommunication networks and the Internet are being re-designed to be energy efficient and enable smarter and sustainable growth.***Contrary to existing solutions, an original advanced holistic approach for energy aware networks is proposed involving both data and control plane. The innovative goals of our solution consist of: (i) investigating local and distributed algorithms and techniques for energy efficient network operations, (ii) studying dynamic, scalable, ad-hoc and optimized resource allocation that balances the trade-offs between energy consumption and network performance, as well as differentiated quality of service (QoS) requirements and (iii) exploring smart standby dynamic power saving strategies to be implemented in both data plane and control plane.***Besides, information and communication technologies (ICT) industry faces a fundamental paradigm shift led by the increasing adoption of software-defined networks (SDN) and network functions virtualization (NFV). Hence, one important issue that will be addressed in my research program is exploiting the potential energy efficiency improvements provided by SDN and NFV in future networks.*******On the other hand, optical networks are widely recognized as a future proof and cost-effective transport technology for supporting the growing traffic volume and services variety at very low energy footprint. However, elastic optical networks (EONs), that may meet the future bandwidth requirements, increases considerably the energy consumption. Furthermore, new generations of data center networks have to provide higher bandwidth efficiency, lower latency, increased flexibility and lower cost. Optical networks interconnection solution is recognized as the best candidate to satisfy these needs. Thus, this proposal brings a special emphasis on the energy-efficient design of EONs taking into account (i) physical layer impairments, (ii) routing, spectrum allocation, and modulation format and (iii) dynamic network operation.***The proposal will provide fundamental knowledge advancement and practical contributions to the area of energy efficient strategies for the next generation of high speed data networks and will provide excellent training opportunities for eight graduate and four undergraduate students. Indeed, this research proposal aims to provide necessary highly qualified people for Canada's economic growth and increased competitiveness. Also, investigating fundamental aspects using the requested discovery grant is expected to exert a leverage effect in order to obtain collaborative or industrial research funds for research projects that focus on practical or implementation aspects.**

互联网流量的显著增长预计将产生许多新的研究挑战，以满足在交换数据信息的数量和速度方面的新要求。事实上，电信网络和互联网正在重新设计，以提高能源效率，实现更智能和可持续的增长。*与现有解决方案相反，提出了一种原创的高级整体能源感知网络方法，包括数据和控制平面。我们的解决方案的创新目标包括：(I)研究用于高能效网络运营的本地和分布式算法和技术；(Ii)研究动态、可扩展、特别和优化的资源分配，以平衡能源消耗和网络性能以及差异化服务质量(Qos)要求之间的权衡；以及(Iii)探索将在数据平面和控制平面实施的智能备用动态节能策略。*此外，随着软件定义网络(SDN)和网络功能虚拟化(NFV)的采用越来越多，信息和通信技术(ICT)行业面临着根本性的范式转变。因此，在我的研究计划中要解决的一个重要问题是开发SDN和NFV在未来网络中提供的潜在能效改进。另一方面，光网络被广泛认为是一种经得起未来考验的经济高效的传输技术，可以以非常低的能源消耗支持不断增长的业务量和服务种类。然而，弹性光网络在满足未来带宽需求的同时，也大大增加了网络的能耗。此外，新一代数据中心网络必须提供更高的带宽效率、更低的延迟、更高的灵活性和更低的成本。光网络互联方案被认为是满足这些需求的最佳方案。因此，这项建议特别强调EON的节能设计，考虑到(I)物理层损伤，(Ii)路由、频谱分配和调制格式，以及(Iii)动态网络运营。*该建议将为下一代高速数据网络的能源效率战略领域提供基础知识进步和实践贡献，并将为8名研究生和4名本科生提供极好的培训机会。事实上，这项研究建议旨在为加拿大的经济增长和增强竞争力提供必要的高素质人才。此外，使用申请的发现拨款调查基本方面，预计将发挥杠杆作用，以便为侧重于实际或实施方面的研究项目获得合作或行业研究资金。
