摘要
提出一种新的邮件过滤模型———基于分布式并行过滤的通用前置式邮件过滤模型PDPF,由此构造的邮件过滤系统,其运行不依赖于特定的邮件服务器而在网关提供过滤服务,对到达的邮件进行并行过滤处理,其分布式并行过滤矩阵通过“并行与”操作,能够加快过滤速度。在真实环境下的实验表明,在日均邮件流量高达10万封的情况下,每封邮件的处理时间不超过50m s。
A novel Prefix Email Filter Model Based on Distributed Parallel Filtering （ PDPF）, was presented in this paper. It provides email filter services in the gateway for any email server. It improves the abilities of parallel processing by using “Parallel And” operation for distributed filter matrix. The filter efficiency will be promoted greatly. Evaluations have been made on real data experiments that the time cost of processing one email is less than 50ms even if there is the influx of 100,000 emails a day.
