Abstract:
1. A network system that realizes a connection between at least one client terminal and plural server apparatuses at least by a connection start signal from the client terminal, a connection provision signal from the server apparatuses, corresponding to the connection start signal, and a connection request signal from the client terminal, corresponding to the connection provision signal, wherein the server apparatuses have an identification information setting means, upon receiving a connection start signal from the client terminal, for setting server identification information for identifying, in the connection provision signal, a specific server apparatus to receive a connection request signal corresponding to the connection start signal, and wherein the server apparatuses include: load information setting means, upon receiving a connection start signal from the client terminal, for setting their own server identification information and their own load information in the connection provision signal sent to the client terminal; load information extracting means, upon observing a connection provision signal sent from other server apparatuses destined for the client terminal, for extracting the server identification information and the load information set in the connection provision signal sent from the other server apparatuses to the client terminal; and server identifying means for deciding a server apparatus to receive the connection request signal from the client terminal, based on the extracted load information of each server apparatus, wherein when the server identifying means decides on another server apparatus sending connection signals destined for the client terminal to receive the connection request signal, the identification information setting means sets the server identification information of the decided other server apparatus in the connection provision signal sent from the server to the client terminal.
