Abstract

The embodiment of the invention discloses an L2TP data processing method and system, and a device, and relates to the field of data communication. According to the L2TP data processing method providedby the invention, an illegal message that needs to be processed on an LNS device is processed at an L2TP tunnel entrance, thereby greatly reducing the processing amount of data messages on the LNS device and saving the resources of the LNS device. The method comprises the following steps: the LNS device configures a message filtering rule, and notifies a corresponding LAC device of the message filtering rule; the LAC device issues the message filtering rule to the L2TP tunnel entrance; after receiving the data message, the LAC device matches the message filtering rule at the L2TP tunnel entrance, if the data message meets the message filtering rule and an execution action is allowing to pass, performs L2TP package on the data message, and sends the packaged L2TP message to the LNS devicethrough an L2TP tunnel.

Description

Technical field [0001] This application belongs to the field of data communication, and in particular relates to an L2TP data processing method, device and system. Background technique [0002] Such as figure 1 As shown, in the existing L2TP (Layer 2 Tunneling Protocol, Layer 2 Tunneling Protocol) networking topology, the client initiates a dial request to the LAC (L2TP Access Concentrator) device, and the LAC device receives the dial request and triggers The LAC device and the LNS (L2TP Network Server, L2TP network server) device establish an L2TP tunnel and session. The client and the LNS device conduct PPP-related negotiations. After the negotiation is successful, the link between the client and the LNS device is opened and data can be exchanged. transmission. As long as the packets that can enter the L2TP tunnel through the search route on the LAC device, they will eventually be sent to the LNS device for processing. When there are illegal packets (such as attack packets or...
