PPPoE network system that can distribute connection requests from PPPoE client terminals to specific PPPoE servers
First Claim
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, andwherein 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.

Abstract
Disclosed is a network system that can distribute connection requests from PPPoE client terminals to specific PPPoE servers under the initiative of the PPPoE servers. In the system that realizes connection between at least one client terminal and plural servers at least by a connection start signal from the client terminal, a connection provision signal from the servers, corresponding to the connection start signal, and a connection request signal from the client terminal, corresponding to the connection provision signal; the servers have an identification information setting means, upon receiving a connection start signal from the client terminal, for setting server identification information for identifying a specific server to receive a connection request signal corresponding to the connection start signal in the connection provision signal.

14. A server apparatus that realizes a connection with at least one client terminal at least by a connection start signal from the client terminal, a connection provision signal from the server apparatus, corresponding to the connection start signal, and a connection request signal from the client terminal, corresponding to the connection provision signal,
wherein the server apparatus has 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 apparatus includes session ID list setting means for setting a list of the session IDs of sessions established by the server apparatuses in a connection provision signal sent to the client terminal; -
signal observing means for observing connection provision signals sent by other server apparatuses destined for the client terminal; session ID list extracting means for extracting a list of the session IDs set in the observed connection provision signals; session ID assigning means for assigning a session ID value not overlapping the extracted session ID values when a connection request is received to establish a new session; and server identifying means for deciding a server apparatus to receive the connection request signal from the client terminal, wherein when the server identifying means decide on another server apparatus sending connection provision 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. - View Dependent Claims (15, 16, 17, 18)
