当前,全球Internet网络规模和业务量以每6～9个月翻一番的速度飞速增长,在我国,预计未来10年骨干网所需的容量将至少是今天的数十、上百倍,超大容量将成为下一代网络的基本特征。中国信息产业部在“十五”规划里也明确指出,我国骨干网的通信能力将提高到大比特级。路由器作为In-ternet通信网络的枢纽和“交通警察”,其地位和作用举足轻重,它的性能直接影响到整个网络的整体性能,因此在整个因特网领域中,路由器技术始终处于核心地位,其发展历程和方向成为整个因特网研究的缩影,是一个国家信息领域的技术水平高低的重要标志。
At present, the global Internet network scale and traffic volume are rapidly increasing every 6 to 9 months. In China, the required capacity of the backbone network in the next 10 years is expected to be at least tens or hundreds of times today. Large capacity Will be the basic characteristics of the next generation of networks. In the “Tenth Five-year Plan”, the Ministry of Information Industry of China also made it clear that the communications capability of China’s backbone network will be raised to the level of big bombs. As the hub and “traffic police” of In-ternet, the router plays an important role and function. Its performance directly affects the overall performance of the whole network. Therefore, router technology is always at the core of the Internet. And direction as a microcosm of the entire Internet research is an important symbol of the level of technology in the field of national information.
