Description
Technical Field
The invention relates to the field of data communication testing, in particular to a method and a system for testing an L2TP tunnel specification.
Background
The maximum Tunnel specification of L2TP (Layer 2 Tunnel Protocol) is an important performance index of a System Under Test (SUT). In the SUT system for performing the L2TP Test, there are two Devices Under Test (DUT) of L2TP Access Concentrator (LAC, L2TP Access Concentrator) and L2TP Network Server (LNS, L2TP Network Server).
The establishment of the L2TP network server Tunnel depends on the L2TP access concentrator, generally, the L2TP session of the L2TP access concentrator is established In the same Tunnel, and for the case of needing to establish a plurality of tunnels, the prior art provides a method implemented by sending Tunnel-Assignment-ID (Tunnel job identification) under a RADIUS (Remote Authentication Dial In User Service) server.
Generally, Tunnel specifications supported by tested equipment of various manufacturers are more than ten thousand, and in order to measure the maximum Tunnel specification of the tested equipment, the traditional method is to configure different Tunnel-Assignment-IDs for each user on an RADIUS server, which is time-consuming, labor-consuming and non-operable.
Another method for testing the maximum tunnel specification of a device is to use a test instrument of a special hardware system, which is usually composed of a specially developed hardware system, and a special embedded operating system runs inside the test instrument, and the test instrument is operated by control software running on a general platform such as a PC, a workstation, and the like.
The existing test instrument can test the maximum tunnel specification when the tested device is used as an L2TP network server. The software setting follows the sequence of single board simulation LAC (PPPoL2TP) - > out Node summary- > Node Setup, and the number of tunnels of each Node is set in the Node setting. Because the number of test instruments and the number of sessions of the device under test are limited, the number of sessions per tunnel is generally set to 1.
However, the method of testing by the testing apparatus can only test the maximum tunnel specification when the device under test is used as the L2TP network server, and the testing apparatus can only be used as a dialer when the device under test is used as the L2TP access concentrator, and cannot test the maximum tunnel specification when the L2TP access concentrator.
In addition, the existing test instrument has expensive price quotation and is not suitable for popularization and application.

Detailed Description
The present invention will be further described with reference to the following drawings and specific examples, but the present invention is not limited to the following examples.
The embodiment of the invention provides a method and a system for testing the L2TP tunnel specification, which are used for testing the maximum tunnel specification of a device to be tested by arranging a simulation server on a computer or other embedded systems or devices.
The simulation server includes all AAA servers. Such as: RADIUS, TACACS (Terminal Access controller Access Control System), and the like.
Example 1
In the embodiment, the analog RADIUS server is selected to be arranged on the computer, and the cost of the arrangement on the computer is low.
Referring to fig. 1, a method for testing the L2TP tunnel specification is provided, wherein an analog RADIUS server is arranged on a computer, and the following steps are executed:
step 101: after the simulated RADIUS server is started, parameter configuration is carried out, namely information such as an authentication port, a charging port and the like is configured. The authentication port is used for receiving the authentication request message, and is a necessary option, and the charging port is used for receiving the charging message, and is an optional option.
Step 102: after the parameter configuration is completed, a message interception auxiliary thread is started, where the message interception auxiliary thread corresponds to the port configured in step 101, that is, whether the configured port receives a message is intercepted.
Step 103: the user dials the tested device and sends an authentication request through dialing. The user may be a virtual user. To test the maximum tunnel specification of the device under test, the device under test may be dialed using an analog dialer, which may dial in batches, each dial corresponding to a user, also referred to as an L2TP session.
Step 104: and after receiving the authentication request, the tested device sends an authentication request message to the simulated RADIUS server.
Step 105: after the simulated RADIUS server monitors the authentication request message, the received authentication request message is recorded and written into a queue, then an ACK (authentication pass) message is returned to the tested equipment, the ACK message carries a Tunnel-Type L2TP and is used for testing the maximum Tunnel specification supported by the tested equipment, the ACK message can also simultaneously carry a Tunnel-Assignment-ID, the Tunnel-Assignment-ID is used for identifying a later established L2TP Tunnel, and simultaneously can also carry an incremental Tunnel-Assignment-ID attribute and other optional attributes configured by some users. When the incremental Tunnel-Assignment-ID attribute is not carried, it is preferable to make the Tunnel-Assignment-ID attribute unique so as to use the number of tunnels established by statistics.
Step 106: after receiving the ACK message, the tested device allows the user to go online, and simultaneously, establishes an L2TP tunnel for the user.
Step 107: by the method, a tunnel is newly established every time a user dials up the tested device, and the test is completed until the user can not be on line any more. At this time, the maximum tunnel specification supported by the tested device can be obtained by counting the number of on-line users, or counting the number of L2TP sessions, or counting the number of tunnels established on the tested device. The method for counting the number of the tunnels established on the tested equipment can adopt a mode of counting the number of the Tunnel-Assignment-IDs, and if the incremental Tunnel-Assignment-IDs are selected, the maximum Tunnel specification of the tested equipment can be directly obtained according to the maximum Tunnel-Assignment-IDs.
Step 108: and releasing the selected ports, namely the authentication port and the charging port, after the maximum tunnel specification supported by the tested equipment is tested.
By the method, the tested device can be an L2TP access concentrator or an L2TP network server.

the ports opened by RADIUS Server (Server) include:
an authentication port and a charging port, wherein the charging port is optional.
Tunnel-Assignment-ID (82) setting:
inputting a character string with the length of 3 and the length of the character string, wherein the character string with the length of 3 is used for identifying the type of the tunnel, and the length of the character string is used for indicating how many characters follow the TAI. The length of the character string input in this embodiment is 10, and an optional increment assignment id (job identification) is also included. For example, according to the setting of the interface, the Tunnel-Assignment-ID of the first Tunnel is established to be TAI 0000000001, the Tunnel-Assignment-ID of the second Tunnel is established to be TAI 0000000002, and so on.
Other attributes include:
shared Key Shared-Key: a field for encryption between the RADIUS server and the access server;
tunnel Client end point Tunnel-Client-Endpoint: to identify the LAC attachment address;
Tunnel-Server-Endpoint: to identify the LNS link address.
Two options are also included: recording the received message and recording the sent message. If the two items are selected, the simulated RADIUS server records the received authentication request message and the sent authentication passing message in a queue. Otherwise, no recording is performed.
