Abstract:
1. A broadband network access method, comprising the following steps: an access unit checking validity of an access request received from a subscriber; for a valid request, removing encapsulation of point-to-point protocol, ATM protocol or other subscriber side link layer protocols from the access request as required, to obtain authentication information of the subscriber; performing a link layer encapsulation at the access network side on the authentication information of the subscriber; and sending the encapsulated authentication information of the subscriber to a control unit via a route switching unit; the control unit controlling an internal or external authentication, authorization and accounting server in authentication of the subscriber; after the authentication is passed, obtaining subscriber configuration information comprising an IP address allocated by the control unit to the subscriber, and sending authentication result and the subscriber configuration information to the access unit via the route switching unit; the route switching unit and the access unit, according to the subscriber configuration information comprising the IP address, allocating corresponding resource to the subscriber, and establishing a data channel for network access of the subscriber; and the control unit managing the route switching unit and the access unit in direct management mode or proxy management mode, wherein in direct management mode, the control unit manages the route switching unit and the access unit directly, and the route switching unit, the access unit and the structural relationship between them are invisible to the user, and in proxy management mode, the control unit does not manage the details of the route switching unit and the access unit, but only forwards management commands to them in proxy manner.
