中文摘要： 如何实现网络的绿色节能高效通信，是目前互联网相关研究中受到广泛关注的前沿课题。当前的绿色网络研究存在一些显著问题，如仅专注于某一层次，缺乏从主流业务特征出发的总体体系结构，缺乏业务层面与硬件层面相互配合的全局优化模型等。本课题拟针对上述问题，以跨层协作为总体指导原则，研究绿色网络的体系结构和节能问题中的关键优化技术。课题拟利用资源矩阵、连接矩阵等方式对网络拓扑、业务流特征、状态信息等进行形式化描述,对网络内容分发业务抽象建模，在此基础上形成全网能耗优化目标函数。并且，拟针对这一规模过大、复杂度过高的优化问题提出一种近似的分布式迭代搜索方法。在上述模型研究基础上，以演进性原则研究绿色网络的体系结构，并且建立博弈模型研究网络运营商和内容提供商针对节能技术推行的激励机制。研究过程中通过构建小规模绿色节能实验平台对优化模型及体系结构进行实验验证。

英文摘要： Nowadays, the widespread concern of topics at the forefront in the internet-related research is how to implement the green energy efficient communication of the internet. There are some significant issues in the current green network research. For example, they only focus on a certain level. There is lack of departure from the mainstream business features. There is lack of the global optimization model and overall architecture whose operational level and hardware level will cooperate with each other. There is also lack of evolvable and departure from the different stakeholders implementation recommendations, and so on. The general idea of this project is the collaborative spirit of cross-layer. It will use the resources matrix and connection matrix to formally describe the business and data flow characteristics as well as status information. It will also make an abstract modeling of the whole network content distribution business. Then it will form the whole network energy consumption optimization goals on this basis. And this optimization problem scale is too large and its complexity is too high. It proposes an approximate distributed iterative search method. On the basis of the above model study, it will use the evolutionary principles to study the green network architecture. And it will establish the Game Mod
