NETWORK SYSTEM AND WEB REDIRECTION METHOD USING THE SAME

摘要

PURPOSE: A network system and a web redirection method using the same are provided to manage the exceptional situations of a client by using a separate VLAN(Virtual Local Area Network) separated from a normal VLAN. CONSTITUTION: An authentication server(104) transmits a authentication result by determining the authentication of a client. A proxy server(103) requests the authentication server of the authentication of a corresponding client by receiving the authentication request of the client. The proxy server transmits the authentication result of the certificate server to the client. A DHCP(Dynamic Host Configuration Protocol) server(107) allocates a DHCP IP to the client in response to the DHCP IP request of the client. A DNS(Domain Name Server)(108) performs the DNS requests of the client. The DNS server returns a redirection URL(Uniform Resource Locator) corresponding to a state code. A network access server(102) connects each of the proxy server, the DHCP server, and the DNS server with the client.
