A study on performance improvement of gateway anti-virus system based on file scanning

This paper discusses the principle and implementation of ldquofile tricklingrdquo methodology in order to solve the timeout problem of anti-virus, by analyzing such problems as timeout and data caching based on anti-virus file scanning. The banker algorithm and TCP congestion window control mechanism have been introduced, an optimization algorithm for data caching has been proposed, and finally, a prototype of gateway anti-virus system based on file scanning has been constructed, in order to verify the feasibility of improving performance.
