In this system, we introduces cluster architecture to provide global and scalable streaming caching proxy service mechanism; We implement streaming media transfer protocol on caching proxy end; We implement layered caching mechanism (global disk caching and memory caching) using dynamic sharing running memory buffer algorithm to support more stable and real-time parallel streams; We implement client request aggregation by means of streaming session sharing to reduce disk I/O and serve more user; We propose single streaming image to support the unify of pre-fetching streaming and caching streaming, which guarantees the proxy streaming of transparency for client; We design and implement streaming pre-fetching mechanism based on packet feedback information to reduce the number of "rebuffering" on client end; We bring forward streaming caching admission control policy fit for streaming caching proxy server to guarantee the QoS of streaming service.

We made some improvements in the system architecture and packet capture module and analysis method of the IDS and got satisfactory results. Based on protocol distributary, the system balances the load, making large numbers of network packets switch to different analysis module according to their protocols. The architecture solves the bottleneck of centralized detection system in which all the packets are sent to analysis module to process and enhances the detection efficiency.

在系统的体系结构上，我们利用协议分流技术进行负载均衡，使得大量的网络数据包按照不同的协议被分流到不同的分析处理模块，解决了集中式检测系统存在的瓶颈问题，即所有的数据包都被送到一个集中的分析模块进行分析、处理，既提高了检测的效率，同时也增强了系统的抗攻击能力，即使某一个分析模块无法正常工作，也不会影响到其他的分析模块。

This paper analyzed data from multiple sources and different structures, concluded three types of info: Login info, Event info, and Packet data info, then created the formation for every type of data; In order to combine future possible new data, IDS using profile and formation string together, create and practice data formation standard algorithm; Because in the collected data, there is info that is redundant or has minor effect on the IDS, this paper discussed the rules of redundant data differentiating and safe data differentiating, Then create data filter rule base; Data collecting system uses distributivity design, collecting module like a black box. we can get data which was filterd and had standard formation, if we created a new model string for new data source. Module work individually; filter data right away at the collecting node.

本文分析了多种来源的、不同结构的数据，将其总结成登录信息、事件信息和网络数据包信息三种类型，并为每种类型的数据设计了固定的格式；为了与将来可能出现的新型数据兼容，采用了配置文件与模式字符串相结合的方法，设计并实现了数据格式标准化算法；由于收集到的数据中存在冗余的信息和对入侵检测影响不大的信息，本文分别讨论了冗余数据辨别规则和安全数据辨别规则，并建立起数据过滤规则库；数据收集系统采用分布式设计，收集器以黑盒形式提供，对新的数据源只需设计一个新的模式字符串，即可得到过滤后的、具有标准格式的数据，各收集器间独立工作；在收集点即对数据进行过滤，只向分析中心报告可疑数据，以减少传输和存储的数据量，降低对网络性能的影响。
