Abstract
Abstract A proxy server apparatus (APP) coupled to a network and a TEL network is disclosed, which comprises: a receiving portion for receiving a request, from a client terminal coupled to the network, for connection to a desired server APP therethrough via the TEL network, the request including a name of the server; an address table for storing the name and corresponding TEL NO.; a PPP connection portion for dynamically assigning an IP address to the desired server APP from the name according to the address table and for providing PPP connection between the desired server APP and the proxy server APP; and a COMM providing portion for providing communication between the client terminal and the desired server APP using the IP address. A proxy server system including a plural proxy server APP is also disclosed, wherein a request is forwarded to a desired server according to a proxy server arrangement table in each proxy server APP and communication is routed through other server APP. The proxy server arrangement table is determined according to distance in TEL network or data rate of the proxy server APP. A server APP is disclosed which informs the proxy server coupled thereto of disconnection when all circuits to the proxy server are in non communication condition for a predetermined interval.
