Due to the dynamic nature of the web, it becomes very difficult for a search engine to provide fresh information to the user. An incremental crawler downloads modified contents only from the web for a search engine, thereby helps reducing the network load. This network load further can be reduced by using migrants. The migrants migrate to the web server for the purpose of downloading, filtering and compressing the documents before transferring them to the search engine side. In this paper a more network efficient approach for extracting the volatile information from the web server using migrants has been developed with the help of table of volatile information, which further helps in reducing the network load significantly.
