Description
Technical Field

Background
With the development of internet technology, network security devices are also receiving much attention. In order to provide power down protection measures for network security devices, related power down protection devices are successively developed. The power down protection device needs a certain switching time to switch between the working state and the closed state. The switching time is used as an important parameter of the power failure protection device and needs to be accurately detected.
A mode for detecting the switching time of power-down protection equipment is characterized in that two ends of the power-down protection equipment are connected with two computers, the computers continuously send ping packets, and the switching time is calculated according to the number of the ping packets overtime. This approach leads to inaccurate detected handoff times due to long packet transmission intervals and low packet transmission rates. Another way to detect the switching time of the power down protection device is to directly connect the power down protection device with a tester, the tester can continuously and stably send packets at a high rate, and the switching time is calculated according to the number of the packet loss.

That is, the prior art either has inaccurate handover time measurement or can accurately detect but cannot realize measurement of long handover time.

In order to make the switching time detection scheme of the power down protection device provided in this specification clearer, the following describes in detail an implementation process of the scheme provided in this specification with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for detecting a switching time of a power down protection device according to an embodiment provided in this specification. In this embodiment, a tester is used as an execution main body for description, but it can be understood that any main body capable of implementing the power down protection device switching time detection scheme provided in this specification may be used as a "tester" as an execution main body, and this specification does not limit this. It should also be understood that any device that can perform the relevant functions in place of the switch in this embodiment may be regarded as the "switch" mentioned in this embodiment.
First, a connection relationship in the present embodiment is explained, and fig. 3 may be referred to as a specific connection relationship. The specific connection relationship is as follows: the tester is directly connected with the switch, the switch is connected with the power-down protection device, and the power-down protection device is connected with the protected device. In this embodiment, the protected device is described by taking a network security device as an example, and it can be understood that all devices that perform power down protection by using a power down protection device may be regarded as "protected devices" in this embodiment. And the switch can be always ensured to be in a normal working state, and an interface which is directly connected with the tester on the switch is always in a communication state. In the testing process, the tester continuously sends test data packets to the switch and receives the test data packets returned by the switch.
When the network safety equipment works normally, the power failure protection equipment sends a test data packet received from the switch to the network safety equipment, the network safety equipment returns the test data packet to the power failure protection equipment, and the power failure protection equipment returns the returned test data packet to the switch.
When the network safety equipment is suddenly powered off in a normal working state, the power failure protection equipment is triggered to be in a starting switching state so as to start the power failure protection equipment to work, and at the moment, because the power failure protection equipment is in the switching state, the power failure protection equipment cannot work normally, the test data packet sent by the switch is lost at the power failure protection equipment.
When the network safety equipment is powered off and the power failure protection equipment is started successfully and works normally, the power failure protection equipment can directly forward the test data packet to the switch, so that the smoothness of the network is ensured under the condition that the network safety equipment is powered off.
When the network safety equipment is plugged from a power-off state, the power-down protection equipment is triggered to be in a closing switching state to close the power-down protection equipment so as to enable the network safety equipment to normally work, and at the moment, because the power-down protection equipment is in the switching state, the power-down protection equipment cannot normally work, a test data packet sent by the switch is lost at the power-down protection equipment.
When the network security equipment is normally plugged and works and the power failure protection equipment is successfully closed, the power failure protection equipment sends the test data packet to the network security equipment, the network security equipment returns the processed test data packet to the power failure protection equipment, and the power failure protection equipment returns the returned test data packet to the switch.
As can be seen, the switching states of the power down protection device include a start switching state and a close switching state. In the starting switching state, when the network safety equipment is powered off, the power failure protection equipment is triggered to start so as to ensure the smooth network; in the switching-off state, the network safety equipment is triggered to be switched off when power is plugged into the network safety equipment, so that the normal work of the network safety equipment is ensured. Both the two switching states may cause the test data packet sent from the switch to be lost at the power down protection device, so that the packet loss time may be considered as the switching time of the power down protection device.
The method is executed by a tester, the tester is directly connected with a switch, as shown in fig. 1, the process includes:
When the tester detects the switching time of the power-down protection equipment, the sending interface of the tester sends a test data packet to the switch, and after the receiving interface of the switch receives the test data packet, the received test data packet is sent to the power-down protection equipment from the sending interface of the switch. The power failure protection equipment is connected with the network safety equipment, and when the network safety equipment is powered off, the network is ensured to be smooth.
In one example, the sending a test packet to the switch includes: and sending a Transmission Control Protocol (TCP) layer data packet to the switch. The tester constructs a TCP layer data packet as a test data packet, and forwards the test data packet at a stable speed. For example, it may be sent out continuously at a rate of ten thousand test packets per second. The sending rate of the test data packet can be set according to the actual detection scene, and generally follows a rule: the greater the rate, the more accurate the detected switching time.
And 102, receiving a test data packet returned by the switch, wherein the switch is used for receiving the test data packet returned by the power failure protection equipment.
And the switch sends the test data packet returned by the power failure protection equipment to the tester, and the tester finally receives the returned test data packet.
In step 101 and step 102, in the process of switching the power down protection device, the interface on the switch directly connected to the tester is always in a connected state, so that the tester is always in a normal working state. When the switching time is longer, even if the power-down protection equipment interface is in a blocking state for a long time, the switch interface directly connected with the tester is always in a communicating state, the tester interface cannot be closed, and the tester cannot be caused to send a package script to stop running, so that the normal work of the tester is ensured, and the switching time is detected.
In the switching process of the power failure protection device, the test data packet cannot be normally forwarded to the tester, and the test data packet is lost. In this step, the number of test packets received by the tester from the switch is subtracted from the number of test packets sent by the tester to the switch to obtain the number of lost packets.
In an example, before calculating the number of dropped packets according to the number of test packets sent to the switch and the number of test packets received from the switch, the method further includes: when the protected device is converted from the power-on state to the power-off state, continuously receiving a test data packet returned by the switch, wherein the test data packet is returned to the switch through the power-down protection device switched from the off state to the working state; when detecting that the current packet receiving rate is consistent with the packet sending rate, determining that the power failure protection equipment is switched; the switching time is used for indicating the switching duration of switching the power failure protection device from the off state to the working state when the protected device is switched from the power-on state to the power-off state.
In this example, the protected device is switched from a plugged-in state to a powered-down state, and the tester detects the start-up switching time of the powered-down protection device. When the tester starts to detect, the protected equipment works normally, the power failure protection equipment is closed, and the sending rate and the receiving rate of the test data packet are consistent; when the protected equipment is powered off and the power failure protection equipment is in a starting switching state, the sending rate of the test data packet is greater than the receiving rate; when the protected device is powered off and the power fail safeguard device is started successfully and normally, the sending rate and the receiving rate of the test data packet are consistent again, and the power fail safeguard device can be confirmed to complete starting switching at the moment.
In another example, before calculating the number of dropped packets according to the number of test packets sent to the switch and the number of test packets received from the switch, the method further includes: when the protected device is converted from a power-off state to a power-on state, continuing to receive a test data packet returned by the switch, wherein the test data packet is returned to the switch through the power-off protection device switched from a working state to a closed state; when detecting that the current packet receiving rate is consistent with the packet sending rate, determining that the power failure protection equipment is switched; the switching time is used for indicating the switching duration of switching the power failure protection device from a working state to a closing state when the protected device is switched from a power failure state to a power plugging state.
In this example, the protected device is switched from a power-down state to a power-on state and the tester detects the off-switch time of the power-down protection device. When the tester starts to detect, the protected equipment is in a closed state and the power failure protection equipment is in a working state, and the sending rate and the receiving rate of the test data packet are consistent; when the protected equipment is plugged and the power failure protection equipment is in a switching-off state, the sending rate of the test data packet is greater than the receiving rate; when the protected device is plugged in and the power down protection device is successfully closed, the sending rate and the receiving rate of the test data packet are consistent again, and the power down protection device can be confirmed to complete closing switching.
And 104, determining the switching time of the power-down protection equipment according to the packet sending rate and the packet loss quantity of the test data packets sent to the switch by the tester, wherein the switching time is used for indicating the state switching duration corresponding to the power-down protection equipment when the working state of the protected equipment is switched.
And dividing the packet loss quantity by the packet sending rate of the tester for stably sending the test data packet to obtain the time of losing the data packet. When the power failure protection device is in a switching state (a switching starting state or a switching closing state), the test data packet is lost, so that the time for losing the test data packet is consistent with the switching time of the power failure protection device, and the switching time is obtained by utilizing the packet loss time.
In an example, after determining the switching time of the power down protection device according to the packet sending rate and the packet loss number of the test data packet sent by the tester to the switch, the method further includes: and clearing all test data used for the switching time detection. For example, the test data may include, but is not limited to: the method comprises the following steps of starting switching time of the power failure protection device, closing switching time of the power failure protection device, total quantity of sending test data packets, total quantity of receiving test data packets or rate of sending data packets and the like. Because, after the switching time of the power down protection device is detected, a detection process is already completed. The relevant test data should be cleared at this time to facilitate the next test.
The method shown in fig. 1 may be used to detect a switching duration from an off state to an on state of the power down protection device when the network security device is powered off from power on, or may be used to detect a switching duration from an on state to an off state of the power down protection device when the network security device is powered off from power off to power on.
On one hand, the switching time detection method of the power failure protection equipment has high speed and can ensure the test accuracy by still using the tester to send the test data packet; on the other hand, the switch is connected between the power-down protection device and the tester, and in the switching process of the power-down protection device, the interface on the switch directly connected with the tester can be always in a connection state, so that the tester is always in a normal working state, and the switching time of the power-down protection device during any switching time can be accurately detected.
