The invention discloses an acceleration method and system of a wide-band access server. A multi-core central processor is arranged in the system. And the system specifically comprises a virtual local area network processing module for deleting or adding virtual local area network information of a message; a message classification module for classifying the message; a message processing module for processing the message according to the message type and obtaining a response message, and then returning the response message to the virtual local area network processing module; the tasks of the virtual local area network processing module, the message classification module, and the message processing module are respectively bound on different CPU cores so as to perform parallel processing. The invention provides a method for accelerating data forwarding and processing speed of a wide-band remote access server in a PPPoE/IPoE wide-band access network; wide-band remote access server equipment can be customized, the price is low, the forwarding efficiency performance is high, the community and like networks are facilitated, and the demands of small and medium size wide-band operators are satisfied.
