Method for testing PORTAL performance of access controller

The invention provides a method for testing the PORTAL performance of an access controller. The method comprises the following steps that: a test tool for simulating an access station (STA) sends network connection requests of a plurality of access stations to the access controller; and after a test tool for simulating a PORTAL server returns an authentication interface to the simulated access stations through the access controller, the test tool for simulating the PORTAL server produces user names and passwords in batch so as to simulate an on-line process of the access stations. According to the method, the cost of the PORTAL server/an RADIUS (remote authentication dial in user service) server and STA in the PORTAL-STA performance test can be reduced, and a feasibility test method can be provided for PORTAL-STA bearing capability in on-line test systems for batch users.
