Abstract

Embodiments of the invention provide a user access method, an SDN controller, a forwarding device and a user access system, and relate to the field of communication. The problem that the traffic of online users forwarded by a vBNG (virtual Broadband Network Gateway) occupies a lot of processing resources of the vBNG in the prior art is solved under the premise of avoiding the influence on the authentication process of users. The method comprises the following steps: an SDN (Software Defined Network) controller acquires device registration information and acquires a first port and a second port according to the acquired device registration information; a forwarding device forwards a user authentication message received from the second port via the first port and forwards a user authentication message received from the first port via the second port according to a first traffic table sent by the SDN controller; the SDN controller acquires the IP address of a user when determining that the user is online; and the forwarding device forwards a message of which the destination IP address is the IP address of the user via the second port and forwards a message of which the source IP address is the IP address of the user via a third port according to a second traffic table sent by the SDN controller. The user access method, the SDN controller, the forwarding device and the user access system are used for user access.

Description

technical field [0001] The present invention relates to the communication field, in particular to a user access method, an SDN controller, forwarding equipment and a user access system. Background technique [0002] Broadband network gateway control equipment (English full name: Broadband Network Gateway, English abbreviation: BNG) is a new type of access gateway for broadband network applications. The provision point of the basic service is used to terminate the user's Point-to-Point Protocol Over Ethernet (English full name: Point-to-Point Potocol Over Ethernet, English abbreviation: PPPOE) connection, aggregate user traffic, and authentication system, billing system and customer management system It cooperates with the service policy control system to realize the authentication, billing and management functions of user access. [0003] In recent years, traditional BNG is generally implemented based on integrated software and hardware. When new services need to be deploye...
