未来互联网的承载网络

The Bearer Network of the Future Internet

未来互联网需要支持窄带业务、宽带业务、固定业务、移动业务以及所有这些业务形态组合而成的业务,业务是变速率的,用户之间的通信是多进程的,因此要求网络具备灵活、有效的全网资源调度能力和支持多进程能力。在未来互联网的承载网的研究中,存在着两种技术路线:改良型技术和革命性技术。改良型技术路线不改变已有IP网的体系结构,而是在其基础上,采用各种技术对原有IP网络进行改良,使其演进为未来互联网;革命性的技术路线是从未来互联网技术和业务应用的需求出发,重新设计的一个新型网络,彻底克服已有IP网无法解决的问题,满足未来信息通信业务发展的需求。

In the future, the Internet will need to support broadband services, fixed services, mobile services, and services involving a combination of these. Such a broad range of services and multi-processes between users will demand flexible and effective network-wide resource scheduling and support. Two kinds of technologies are being studied in relation to the bearer network of the future Internet： improved technology and revolutionary technology. As opposed to changing the existing IP network architecture, improved technology builds upon it, using various techniques to achieve improvement. Revolutionary technology is a future Internet technology, which seeks to address future business demands by completely re-designing the network, thereby overcoming problems that cannot be solved by current IP networks.
