Description

Testing equipment and testing system

technical field

The utility model relates to communication technology, in particular to a detection device and a detection system.

Background technique

In the testing process of data network equipment, due to the need to analyze data information, a hub (HUB) is often used instead of a switch (Switch) between the device under test (DUT) and the test terminal. The reason for using HUB is: HUB is a pure hardware network underlying device, and HUB is not targeted when sending data, but uses broadcasting to send. That is to say, when the HUB wants to send data to a certain node, it does not directly send the data to the destination node, but sends the data information to all nodes connected to the hub. In this way, it becomes possible to connect a test terminal to monitor data information on any interface.

Since the HUB adopts the method of sharing the transmission line, which is a disorderly working state without management and dredging, each device connected to the HUB will try to seize the communication channel as much as possible, so when multiple devices seize the channel together, a network is formed. In the case of congestion, when the number of data and users exceeds a certain limit, it will cause a serious decline in network performance. The switch sends each information packet independently from the port to the destination port according to the destination address of the transmitted information packet, which avoids collision with other ports and improves the actual throughput of the network. Therefore, in actual network applications, switches have all replaced HUBs.

However, the characteristics of the switch sending data information according to the port makes it impossible for the test terminal to monitor the data and analyze the data information. Therefore, the HUB is still used in the experimental environment. This causes the inconsistency between the experimental environment and the actual application environment, which affects the accuracy of the test results.
