PURPOSE: A VPN(Virtual Private Network) system for supporting a multi-tunnel IPSec(Internet Protocol Security protocol) and a method for operating the same are provided to create a plurality of VPN tunnels using many lines for an identical VPN network parity and to use them at the same time. CONSTITUTION: A multi-tunnel VPN equipment is divided into an application module(100) and a core system module(200). The application module(100) consists of a VPN connection management part(101), a multi-tunnel traffic policy management part(102), an IKE(Internet Key Exchange) part(103), and a connection state monitoring part(104). The core system module(200) consists of a connection state monitoring interface part(201), a core engine part(210), and a transceiver part(220). The core engine part(210) is composed of an IPSec security policy database(211), an IPSec core engine part(212), an IPSec multi-tunnel part(213), and an encoding/decoding part(214). The transceiver part(220) comprises a sender-based multi-path routing part(221), a traffic monitoring part(222), n numbers of transmitting devices(223), and n numbers of receiving devices(224). The connection state monitoring part(104) and the connection state monitoring interface part(201) are to monitor the state of the core system module(200) at the application module(100). At this moment, the IKE part(103), the IPSec security policy database(211), the IPSec core engine part(212), and the IPSec multi-tunnel part(213) form an SA(Security Association) management part(230).
