A network system includes a plurality of servers, a plurality of load balancing apparatus and at least one routing apparatus. Each load balancing apparatus is connected to two or more servers of a plurality of servers. Each routing apparatus is connected to two or more load balancing apparatus of a plurality of load balancing apparatus and to a network. Each routing apparatus receives an access packet for a plurality of server apparatus from the network and forwards the access packet so received to an arbitrary one of the two or more load balancing apparatus connected to the routing apparatus. Each load balancing apparatus receives an access packet from each routing apparatus and transfers it to an arbitrary server among the two or more servers connected thereto.
