The multi-relay Internet big data push method and system include interface management, task management, name registration, data preprocessing, data push, data relay, data reception, data verification management, and buffer data management. The application instance completes the precise delivery task of big data push through name registration and login, including the method and process of receiving big data push task, processing, pushing, relaying, receiving, reviewing, and delivering, as well as its full two-way working mode. After the system based on the above method is properly deployed, it can push huge data from one common Internet access point to another remote Internet access point completely reliably, efficiently and automatically; one-to-many push, offline push, access When the terminals belong to different Internet access operators, etc., the system of the present invention selects a suitable relay route, avoids data channel bottlenecks between Internet access operators, and effectively utilizes ADSL asymmetry.
