网络生态学:一种研究无边界网络生存性的新方法

无边界网络的复杂性及其它特性,包括没有全局可见度、信任关系模糊、无集中控制以及多管理域等,使得对无边界网络的生存性研究面临许多挑战.生态学对于自然界的建模分析法提供了认识复杂系统的基本方法,已经在计算机网络的某些领域得到应用.笔者分析了无边界网络的特点和生存性研究所面临的问题,讨论了将生态学理论应用于无边界网络生存性研究的构想.

Cyber Ecology:a New Method for Studying the Survivability of Unbounded Networks

The survivability of unbounded networks is a difficult and challenge problem because of the complexity and other characteristics,including the absence of global visibility,the untrustworthy relationship,the absence of central control and multi administrative domains,of unbounded networks.Ecology modeling and analysis methodologies to understand the natural systems provide a basis for insight into complex systems and have been introduced into the computer network systems.In this paper,the properties and survivability issues about unbounded networks are revealed and analyzed and the formulation of applying the ecology methodologies to studying the survivability of unbounded system is discussed.
