面向可扩展路由体系的地址空间分离技术研究

Study on Separated Address Space Technology for the Scalable Routing Architecture

随着互联网的高速发展,多宿主、流量工程、支持主机移动性等新型服务需求逐步产生,使得当前互联网体系架构正面临严重的可扩展性问题.专家学者正通过不同方式设计并开发新型网络体系模型以解决上述问题.在各种模型中,基于地址空间分离的解决方案广受推崇.首先对基于地址空间分离技术中的关键问题和难点进行了分析;随后介绍了4种典型模型,并对其进行了深入的分析及优缺点的比较;最后,基于现有技术对未来构造完善的可扩展路由体系的发展方向进行展望.

With the rapid development of Internet, multi-homing, traffic engineering, supporting host mobility and other new services needs produce gradually, which make the current Internet architecture in face of grave scalability problems. Experts and scholars are designing and developing a new network architecture to solve these problems in different ways. Solution based on address space sepa- ration is widely respected in a variety of models. This paper analyzes the key problems and difficulties in address space separation technology first; Then it introduces four kinds of typical model, and its in-depth analysis and comparative advantages and disadvanta- ges ; Finally, it looks into the future development direction of construct perfect scalable routing architecture based on existing technologies.
