Number matching method and device of L2TP (layer 2 tunneling protocol) network simulation system

Abstract

The invention relate to a number matching method and device of a L2TP (layer 2 tunneling protocol) network simulation system. The method comprises the following steps: a data packet monitoring unit monitors LAC output port signals of an access concentrator, and intercepts a data packet sent by the LAC output port; the data packet is used for establishing the data communication between UE (user equipment) and L2TP network server LNS, and comprises an IP address of LAC, a serial port identification of the LAC and a target receiving terminal identification of the data packet; a preset file of the UE is found out according to the IP address of the LAC and the serial port identification of the LAC, and a called number and a calling number of the UE, wherein the a called number and the calling number of the UE are extracted from the preset file; the called number and the calling number are added to the data packet; a changed data packet is sent to the target receiving end according to the target receiving terminal identification of the data packet. According to the method and the device, the simulation of accessing the L2TP network by terminal dialing is realized, so that the access operation process of a wireless data special network is restored truly.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a number allocation method and device for a network simulation system of the Layer 2 Tunneling Protocol (L2TP). Background technique [0002] Layer 2 Tunneling Protocol (Layer 2 Tunneling Protocol, L2TP) is an industry standard internet tunneling protocol. In broadband communication network and mobile communication network, terminal equipment dial-up mode is widely used to access L2TP network. Especially for wireless data private network products based on mobile communication networks, it uses dial-up access to the L2TP network to connect wireless terminals to the enterprise's L2TP network server (L2TP Network Server, LNS) through the L2TP Access Concentrator (L2TP Access Concentrator, LAC). ). Among them, in the L2TP protocol, the LAC and the LNS are devices at both ends of the L2TP tunnel, the LAC initiates a tunnel establishment request to the LNS, and the LNS accepts ...
