分布式系统

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。

It is found that the distributed microscopic traffic network simulation methods based on distributed systems require not only the careful discussions on traditional traffic flow theory, such as the driver's uncertain behaviors in selecting the route and changing lane, but also some deep researches on parallel techniques. These key techniques about how to realize parallel and distributed simulations include how to partition the large-scale road network into sub-areas, how to divide the multi-course in dynamic traffic flow operation, how to finish the informational transmission among processors, and how to realize the clock-synchronization among processors etc..
