Initially, hash indexing was developed to support fast searches in files in the file system. 最初,hash索引用于支持文件系统中的文件快速搜索。
The accessing-by-name characteristic of HASH function in the RDOS file system is used. The collision processing and estimative analysis is al-so dealt with. 本文利用了RDOS文件系统中的HASH函数按名存取的特点,还论述了碰撞处理与判断分析。
Then write hash algorithm to store and organize user nodes and message nodes, send the user information which appears unusual situation from kernel space to user space through the/ proc file system. 编写哈希算法把用户节点和信息节点存储组织起来,借助系统的/proc文件把流量异常的用户信息从内核发送到用户空间。
