主动网络试验模型的研究

1.引言当今网络技术正在飞速发展,Internet取得了巨大成功,近十年来网络新技术虽然层出不穷,但是相应的网络灵活性较差,协议的标准化和兼容性成为网络技术发展的主要障碍。在传统的网络体系结构中,网络层和传输层是整个网络变化的瓶颈部分,这是因为网络层和传输层是不同物理网络之间进行互联的基础,也是不同系统应用层之间进行互通的基础,因此只有保持网络层和传输层相对稳定才能提供一个稳定的网络服务,在网络层和传输层每一点变化都要经历漫长的标准化过程。这个过程往往要持续数年,并且它的改动大部分要经过手工配置才能最终投入运行。另外,对于网络层和传输层

The Research of the Experiment Model of Active Network

Traditional Internet architecture is lack of flexibility and process of protocol standardization and compati-bil-ity is time-consuming and costly. Active network (AN) is one of the approaches to solve these technical problems.AN uses open intermediate nodes that make the network to be programmable. Active codes of the message create newnetwork service dynamically and this makes the network architecture more flexible. This paper gives an AN experi-mental modal and this modal is simulated and analysed systematically.
