The Research And Application On IP Network Traffic Clean

The development of Web Application and other network application has changed people's life. They make our life more colorful and more convenient. The content in the net traffic is becoming more and more varies. Such as web application traffic, P2 P application traffic, game application traffic, and attack traffic, etc. Some links in web pages and posts in forums is not suitable for children and teenagers. Those problems make the school network unhealthy and unregulated. This thesis studies those problems and puts forward a traffic clean solution.This thesis studies technologies about traffic clean, implements a transparent network bridge to capture and forward traffic packets. Using this method will not affect the whole network of school; Making uniform rules to identify traffic packets. This thesis studies pattern matching algorithm and classify rules by network protocol characteristics. This makes the pattern matching algorithm faster; By classifying rules, reduce the account of rules to match, this will improve matching speed.This thesis propose a method: using rule's prefix to classify rules. This method is faster than normal multi-pattern match algorithms when then number of prefix is small. This method reduces the amount of match patterns and is easy to use in practice.This thesis propose a solution about school traffic clean. This thesis designs and implements a traffic clean system to clean and regulate school network. It works in test environment.
