Connection management system, and a method for linking connection management server in thin client system
First Claim
1. A connection management system comprising a plurality of connection management servers each managing a connection from a thin client terminal to a thin client server, whereineach of the connection management servers comprises:
- a server configuration information table which stores, for each of the connection management servers, identification information of a group to which the connection management server belongs;
a request window unit which accepts a connection request from the thin client terminal, selects a connection management server which executes the search of the client based on a group specified by a user, and transmits a search request to the selected connection management server; and
a connection destination management unit which receives the search request, and selects a connectable client out of target clients that can be assigned to the thin client terminal to respond to the request, whereinthe connection management servers manage states of clients in order to hold the states of the clients, and each of the connection management servers executes a search of a client available for the thin client terminal according to a connection request from this thin client terminal, and replies with the search result to the thin client terminal, anda range of the connection management servers for executing the search of the client is limited in response to the states of the clients and a load situation of the connection management servers for each connection request from the thin client terminal to the thin client server;
and wherein each of the connection management servers undertakes acceptance of the connection request from the thin client terminal, and response of the result of selecting a connectable client, and refers to a configuration information table which stores information on each of the connection management servers, when a range of destinations of transferring the connection request from this thin client terminal is determined.

Abstract
An exemplary object of the present invention is to suppress the load on each server and network traffic. To achieve this, a plurality of connection management servers are installed so that any of the connection management servers executes acceptance of a connection request from a thin client terminal. Further, the connection management servers manage the states of clients in order to hold the states of the respective clients, and each of the connection management servers searches a client that can be connected by the thin client terminal according to a connection request from this thin client terminal, and replies with the search result to the thin client terminal, and a range of the connection management servers for executing the search of the client is limited for each connection request from the thin client terminal to the thin client server.

4. A method for linking a connection management server in a thin client system having a plurality of thin client terminals, a thin client server having a client which is connected from the thin client terminals to execute applications, and the connection management server which manages connection from the thin client terminals to the thin client server,
wherein each of the connection management servers comprises: -
a server configuration information table which stores, for each of the connection management servers, identification information of a group to which the connection management server belongs; a request window unit which accepts a connection request from the thin client terminal, selects a connection management server which executes the search of the client based on a group specified by a user, and transmits a search request to the selected connection management server; and a connection destination management unit which receives the search request, and selects a connectable client out of target clients that can be assigned to the thin client terminal to respond to the request; the method comprising the steps of; installing a plurality of connection management servers so that any of the connection management servers executes acceptance of a connection request from the thin client terminal; the connection management servers managing states of clients in order to hold the states of the respective clients, and each of the connection management servers searching a client that can be connected by the thin client terminal according to a connection request from this thin client terminal, and replying with the search result to the thin client terminal; and limiting a range of the connection management servers for executing the search of the client in response to the states of the clients and a load situation of the connection management servers for each connection request from the thin client terminal to the thin client server; and wherein each of the connection management servers undertakes acceptance of the connection request from the thin client terminal, and response of the result of selecting a connectable client, and refers to a configuration information table which stores information on each of the connection management servers, when a range of destinations of transferring the connection request from this thin client terminal is determined.
