INTERNET SERVICE SYSTEM HAD TRAFFIC DISTRIBUTING AND BACKUP FUNCTION ON INTERNET

摘要

PURPOSE: An Internet service system having a traffic spread and backup function in an Internet using environment is provided to always offer a service when an obstacle is generated at any side on an Internet service by automatically sensing the obstacle when the obstacle is generated in a network dedicated line and an ADSL modem/cable modem, setting an Internet connection on a network as a backup line, and spreading a traffic. CONSTITUTION: A router(14) for the very high speed Internet stores information to IP addresses of host PCs(12) connected through a hub(15) in an internal backup table. The router(14) periodically transmits data so that it is always monitored that a network dedicated router(11) is normally operated and checks a state of the network dedicated router(11). The router(14) senses an obstacle when the obstacle is generated in a network dedicated line(10) and sets an Internet connection of all networks as a very high speed Internet line(13) so that the host PCs(12) receives services through the very high speed Internet line(13). If the obstacle is generated in the very high speed Internet line(13), information of the internal backup table of the router(14) is transmitted to the network dedicated router(11) for receiving Internet services through the network dedicated line(10) and providing a reliable network to a user.
