A Study of the Internet Infrastructure for Providing Safe and Secure Information Services

研究的目的和取得的成果如下：1)为了降低维护成本：提出了DBMS共享方法和贝叶斯网络的引入；2)为了提高区分能力：提出了一种使用GPGPU支持核心网设备的方法，并提出了专门的缓存结构；3)在实时处理方面：实现了路由器的软件仿真器SLIM；4)在P2P检测方面：在SLIM5上实现了基于哈希的内容搜索功能))低延迟路由：提出了增减式的路由表更新算法。

The purposes and their achievements are shown as follows.1) As the reduction of a maintenance cost: DBMS sharing method and the introduction of Bayesian network was proposed.2) As the improvement of the discrimination ability: a method for using GPGPU is proposed to support devices in core networks and specialized cache architecture was proposed.3) As real-time processing: SLIM, a software emulator of proposed router was implemented4) As P2P inspection: hash based contents search function was implemented on SLIM5) Low-latency routing: incremental and decremental updating algorithm of routing table was proposed.
