Compared with traditional invasion detection system has a lot of advantages to invade the detection system distributed: Distributed IDS is that a lot of measures the land to different data sources, adopts different measuring algorithms, measure together, cooperate and deal with, has improved the accuracy measured ; But distributed IDS can be used in the extensive network environment; Distributed IDS may use the special package to be punish and audit datum safely, help the system to be produced and invade the rule of measuring and produce and unusually measure models ; Distributed IDS analyses the behaviors of a lot of control points in coordination, may measure out and attack distributed in coordination ; The measuring of distributed IDS right a certain control point can be regarded as the early warning of other check points .

分布式入侵检测系统跟传统的入侵检测系统相比有很多优点：分布式IDS是多个检测域针对不同的数据来源，采用不同的检测算法，共同检测，协作处理，提高了检测的准确性；分布式IDS却可以用于大规模的网络环境；分布式IDS可以使用专门的组件处理安全审计数据，帮助系统生成入侵检测规则和生成异常检测模型；分布式IDS协同分析多个监控点的行为，就可能检测出分布式协同攻击；分布式IDS对某个监控点的检测可以作为对其他检测点的预警。

Several experimental applications have been developed finally. In this paper, there areinnovations from the following four aspects:1. Definition and research methods of current distributed system and distributedinteractive simulation system follow those of traditional parallel computing system.While this paper points out it is one-sided to measure the scalability just from thenumber of processors and performance of a system, because the resources of distributed systems are heterogeneous and they can be used in diverse applications. Inthis paper, scalability of distributed interactive simulation platform is defined as theability of scaling (including scale-up and scale-down) in functionality and performanceof systems which is run on the platform when number of processors and otherhardware resources such as network change, i.e. when problem size is scaled up and system resources is increased, the performanceremains fixed and it is easy to expand the functions of simulationapplications.

本文的创新工作主要体现在下述4个方面：1、现有的分布式系统和分布式交互仿真系统可扩性的定义和研究方法都沿用了传统的并行计算系统可扩性的定义和研究方法，本文指出分布式系统的系统资源异构多样、应用种类丰富多样，只从传统方法采用的处理机资源和性能角度衡量一个系统是否可扩是有一定的片面性，提出了分布式交互仿真平台可扩性的定义是在处理机和网络等系统资源变化时，运行在平台上的分布式交互仿真系统在性能和功能方面发生扩缩的能力，即当问题规模扩大时，增加系统资源，系统能获得指定的性能及在功能方面能方便进行扩充。

By our methodology, every information exploitation behavior happened in networks is always associated with proliferating some information contents among the networks to a certain extent, so that some self-organized distributed patterns in terms of different information contents and different content granularities will be generated by a great number of radom information proliferations in the networks.

按照本文的信息利用模式，网络信息利用行为总是伴随着信息内容在网络中的扩散，网络信息利用行为成为有后效的和相关的，从而导致不同信息内容和不同内容粒度的分布式的信息自组织结构，形成基于这种信息自组织结构的网络信息利用模式。
