Abstract

Embodiments of the present invention provide a user access method, an SDN controller, a forwarding device, and a user access system, which relate to the field of communication and can solve the problem of the online access problem in the prior art on the premise of avoiding the impact on the user authentication process. The problem that the user's traffic is forwarded by the vBNG occupies more processing resources of the vBNG, including: the SDN controller obtains and obtains the first port and the second port according to the obtained device registration information, and the forwarding device sends the first flow table according to the SDN controller The user authentication message received from the second port is forwarded from the first port, and the user authentication message received from the first port is forwarded from the second port; when the SDN controller determines that the user is successfully online, it obtains the user IP address, the forwarding device forwards the packet whose destination IP address is the user IP address through the second port, and forwards the packet whose source IP address is the user IP address through the third port according to the second flow table sent by the SDN controller. The present invention is 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...
