Description

Technical Field

[0001] The present invention relates to the technical field of network port compatibility testing, and more specifically, to a network port compatibility testing device and method. Background Art

[0002] With the rapid development of network technology, the network port speed of current communication equipment has been significantly improved, and home routers and other devices have begun to be equipped with 2.5G, 5G and even 10G high-speed network ports. However, the network port speed of most network terminals, such as set-top boxes and desktop computers, is still mostly 1000M or 100M, or even 10M, which is significantly lower than that of high-speed devices. In addition, most ordinary users lack the ability to reasonably configure the network port speed and negotiation mode, which puts higher requirements on the automatic negotiation mode of the network port of communication equipment such as home routers.

[0003] Currently, most network port compatibility tests are limited to different rate negotiation tests between two network devices, and there is a lack of solutions that can test the compatibility of a device under test with multiple network ports at one time. The one-to-one testing method is not only time-consuming and inefficient, but also has obvious deficiencies in scalability, making it difficult to meet the requirements of rapid iteration of current network devices and diversified user needs.

[0091] Example 3

[0092] In a specific embodiment, the test network is as follows: Figure 4As shown, the host computer is a computer, which is connected to the LAN 1 port of the router to be tested through the network port, and the computer is connected to the host computer interface of the converter through the USB interface. The port 0 of the converter is connected to the LAN 2 port of the router to be tested, and the ports 1, 2, and 3 of the converter are connected to different low-speed terminal devices respectively.

[0093] The router to be tested is initially configured as follows: the LAN interface of the router to be tested is in auto mode, and the DHCP server function is enabled.

[0094] Test process reference Figure 5 As shown:

[0095] After the test starts, the converter reads the network port capability sets of port0 and port1 through signal acquisition, obtains the network port capability sets of the router to be tested and the low-speed terminal device connected to port1, and then compares the capability sets of both parties to select the highest rate and full-duplex mode supported by both parties as the preset values;

[0096] Then control the connection between port0 and port1 of the converter, and then access the router management interface on the computer to check the status of the LAN2 port of the tested router;

[0097] If the LAN2 port of the tested router is in down state, it means that the tested terminal device connected to the port1 port of the tested router has failed to negotiate with the network port of the tested router, and the computer records the test result. Then the computer will control the next port of the adapter to connect to port0 and restart the test;

[0098] If the LAN2 of the router under test is in the up state, the computer should compare the negotiated connection rate and duplex mode results of the LAN2 port of the router under test with the expected values ​​to determine whether the negotiation is successful.

[0099] If the connection rate and duplex mode results negotiated by the LAN2 port of the router under test are consistent with the expected values, the negotiation is successful; if the connection rate and duplex mode results negotiated by the LAN2 port of the router under test are inconsistent with the expected values, the negotiation is unsuccessful;

[0100] If the negotiation fails, the computer needs to record the connection rate and duplex mode of the LAN2 port of the router to be tested, the expected value, and the conclusion of the negotiation failure. Then the computer will control the next port of the adapter to connect to port0 and restart the test;

[0101] If the negotiation is successful, the computer should record that the negotiation result of port 1 of the router under test is in line with expectations.

[0102] The computer will then connect the next port of the control adapter to port0 and restart the test.

[0103] Repeat the above process until all ports of the connector have been tested.
