摘　　要：1.引言随着Internet的迅速发展,用户对网络服务的需求变化快,在需要高带宽的实时多媒体通信和只需低带宽的无线移动计算两方面的需求都很显著.尽管Internet的带宽增长速度十分迅速,但由于目前Internet体系结构的限制,网络提供商无法针对用户需求变化而及时地提供相应服务,主动网络(ACtiVe Network)的出现为解决这一难题提供了新的思路[1,2,4].The architecture of traditional networks has limited the development of new protocols and applications and the evolution of Internet infrastructure. The emergence of active networks provides a possible approach. Active network is a programmable network in which user can insert customized programs into the switches of the networks. As a kind of novel network architecture, active networks are advantageous in creating and tailoring new network services and improving the flexibility of networks, which makes it one of the promising directions in the Internet. In this paper, we discuss the background, principles and architecture of active networks, as well as the applied fields and the problems to be solved in the future.
