摘要互联网体系结构评估模型是推动互联网体系结构持续发展的理论支撑，它可以为运营商提供网络体系结构设计的相关建议，从而使运营商可选取最适合的协议或机制构建符合各种应用需求的互联网体系结构．随着互联网应用日趋多样化，互联网的安全性、稳定性、移动性等面临越来越大的挑战．互联网体系结构的演进已经成为学术界和工业界的共识，面向现有体系结构问题的修补策略以及革命式的体系结构方案不断被提出，借鉴前者的稳定性和后者的创新性，我们提出了一种基于演进式的互联网体系结构发展思路．为了更好地了解各种互联网体系结构发展方案，近年来，研究人员分别从协议、框架等不同方面对体系结构的服务能力、发展能力和安全能力进行了评估，互联网体系结构评估方法已经成为未来互联网体系结构研究的一大热点．文中介绍了与互联网体系结构发展密切相关的五种特性的基本评估模型，包括可服务性、可扩展性、可部署性、可演化性和可信性评估模型；归纳了用于构造互联网体系结构评估模型的机制，重点讨论了效用机制在这五类基本评估模型中的应用；并对用于实现互联网体系结构评估的若干方法进行了总结．基于上述讨论，文中最后从互联网体系结构的内在特性和外在特性出发，提出了一种基于适应能力的互联网体系结构可演进性评估系统，并对互联网体系结构评估领域的发展进行了展望．

Abstract Internet architecture assessment model is to promote the sustainable development of the Internet architecture to support the theory , it can provide network architecture design recommendations for operators , so that operators can select the most suitable mechanism to build agreement or meet the needs of various Internet applications architecture. With the growing diversity of Internet applications , Internet security , stability , mobility , etc. facing increasing challenges. Evolution of the Internet architecture has become the consensus of academia and industry , repair strategies and revolutionary architecture solutions for existing structural problems of the system continue to be made , drawing the latter's former stability and innovation, we propose an evolution of the Internet architecture style based on the development of ideas . In order to better understand the various Internet architecture development programs , in recent years , researchers from different aspects of the agreement, the service frameworks , capacity development and security capabilities were evaluated architecture , structural assessment methods have become the next Internet system structure of a hot Internet system. This paper introduces the basic assessment model and structure of the system is closely related to the development of the Internet of five properties , including serviceability , scalability , deployability , evolvability and credibility assessment models ; summed up the Internet architecture for constructing mechanisms for evaluation model , focusing on the utility of the mechanism used in these five basic assessment model ; Internet architecture and evaluate several methods for achieving summarized. Based on the above discussion , the final text from the
