Description

Method and device for detecting server state

Technical Field

The present application relates to the field of data communication access technologies, and in particular, to a method and an apparatus for detecting a server status.

Background

The user escape function can meet the requirement of the user to access network resources under the condition that the authentication server cannot work normally. The basic process of the user escape function is that when the access equipment detects that the state of the authentication server is off-line, the access equipment can grant a specific network access right to a user, so that the basic network access requirement of the user is met. Therefore, the accurate detection of the state of the authentication server is a precondition for ensuring the normal starting of the escape function of the user and also a precondition for meeting the basic network access requirement of the user.

An existing method for detecting the state of an authentication server is described by taking a remote authentication in user service (RADIUS) as an example. An access device (e.g., a Network Access Server (NAS)) determines the state of the RADIUS server by detecting whether an interruption occurs for two consecutive detection periods. And determining whether the detection period is interrupted or not by comparing the times that the NAS does not receive a response message sent by the RADIUS server in the detection period with a threshold value. When the method is adopted to detect the state of the RADIUS server, the accuracy of the detection result is not high. For example, when the threshold is set to be small, when the NAS accesses more users, it is easy to misjudge that the RADIUS server is faulty or offline. For another example, when the threshold is set to be large, in the case of a NAS accessing a small user, it is easy to miss detection that the RADIUS server is faulty or offline.

Therefore, how to effectively detect the state of the server is an urgent problem to be solved at present.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

This application is intended to present various aspects, embodiments or features around a system comprising a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. Furthermore, a combination of these schemes may also be used.

Fig. 1 shows a schematic flowchart of a method 100 for detecting a server status according to an embodiment of the present application.

As shown in fig. 1, the method 100 for detecting the server status includes steps 110 to 130, which are described in detail below.

In step 110, the network device sends N authentication request messages.

The N authentication request messages correspond to the N response messages one by one, each authentication request message is used for indicating the server to send the response message corresponding to each authentication request message to the network equipment, and N is a positive integer greater than or equal to 2. That is, one authentication request message corresponds to one response message, and the server may send the response message corresponding to the authentication request message to the network device according to the received authentication request message.

Specifically, the network device sends N authentication request messages, where an ith authentication request message corresponds to an ith response message, i is a positive integer, and i is greater than or equal to 1 and less than or equal to N. And the server sends an ith response message to the network equipment according to the received ith authentication request message.

Illustratively, the network device sends 2 authentication request messages, which are an authentication request message a and an authentication request message B. The authentication request message a corresponds to the response message a, and the authentication request message B corresponds to the response message B. The server sends a response message A to the network equipment according to the received authentication request message A, and the server sends a response message B to the network equipment according to the received authentication request message B.

In the embodiment of the present application, the number of the N authentication request messages sent by the network device is not specifically limited. For example, the network device sends 2 authentication request messages. As another example, the network device sends 5 authentication request messages. For another example, the network device sends 8 authentication request messages.

It should be understood that the sending time of the N authentication request messages sent by the network device may be different.

Illustratively, the network device sends 3 authentication request messages, which are an authentication request message a, an authentication request message B, and an authentication request message C. The network device transmits an authentication request message a at time #1, an authentication request message B at time #2, and an authentication request message C at time #3, and the time #1, the time #2, and the time #3 are different.

Step 120, the network device obtains the first information and/or the second information,

in an embodiment of the present application, the first information includes a first time and a second time.

The first time is the time when the network device does not receive the first response message, the first response message is one of the N response messages which is not received by the network device for the first time, the second time is the time when the network device does not receive the second response message, and the second response message is one of the N response messages which is not received by the network device for the last time.

Specifically, the first response message is a response message in N response messages that the network device has not received for the first time, and it can be understood that j is a positive integer, and j is greater than or equal to 1 and less than or equal to N.

For example, suppose that the network device sequentially sends a total of 3 authentication request messages, which are an authentication request message a, an authentication request message B, and an authentication request message C. The response message a corresponds to the authentication request message a, the response message B corresponds to the authentication request message B, and the response message C corresponds to the authentication request message C. And the response message which is not received by the network equipment for the first time is a response message A. In this case, the response message a is the first response message.

Specifically, the second response message is a response message in the N response messages that have not been received by the network device for the last time, which may be understood as that the network device has not received the kth response message in the N response messages, k is a positive integer, and k is greater than or equal to 1 and less than or equal to N. For example, suppose that the network device sequentially sends 3 authentication request messages, which are an authentication request message a, an authentication request message B, and an authentication request message C. The response message a corresponds to the authentication request message a, the response message B corresponds to the authentication request message B, and the response message C corresponds to the authentication request message C. And the response message which is not received by the network equipment for the last time is the response message B. In this case, the response message B is the second response message.

In the embodiment of the present application, a manner in which the network device determines that the response packet is not received is not specifically limited.

In some embodiments, when the network device receives a response packet corresponding to the authentication request packet within a predefined time, it may be determined that the network device receives the response packet; when the network device does not receive the response packet corresponding to the authentication request packet within the predefined time, it may be determined that the network device does not receive the response packet.

For example, assuming that the predefined time is 1 minute, the network device sends the authentication request message a at 10.

For convenience of understanding, the first time and the second time are described by taking as an example whether the response message is received within the predefined time and determining whether the network device receives the response message.

In some embodiments, when the network device does not receive a response packet corresponding to the authentication request packet within a predefined time, it may be determined that the network device does not receive the response packet. In this case, the time when the network device does not receive the response message is the time when the network device sends the authentication request message plus the predefined time.

Specifically, the predefined time is T, and the time for the network device to send the authentication request packet a is T. In this case, it may be determined that the time corresponding to the network device not receiving the response packet a is T + T. The response message a corresponds to the authentication request message a.

Illustratively, the network device sequentially sends 2 authentication request messages, specifically, the network device sends an authentication request message a at 10. The authentication request message A corresponds to the response message A, the authentication request message B corresponds to the response message B, and the predefined time is 1 minute. The network device does not receive the response message a at 10. In this case, the first time may be determined to be 10, and the second time may be determined to be 10.

Illustratively, the network device sequentially sends 3 authentication request messages, specifically, the network device sends an authentication request message a at 10. The authentication request message A corresponds to the response message A, the authentication request message B corresponds to the response message B, the authentication request message C corresponds to the response message C, and the predefined time is 1 minute. The network device does not receive the response message a at 10. In this case, the first time may be determined to be 10, and the second time may be determined to be 10.

In the implementation of the present application, the second information includes the number of times of the first non-response and the number of times of the second non-response.

The first non-response times are times of response messages which are not received by the network equipment in a first period, the second non-response times are times of response messages which are not received by the network equipment in a second period, and the first period and the second period are two continuous periods.

Specifically, the number of times of the first non-response is the number of times that the network device does not receive L response messages in the first period, the L response messages are L response messages in the N response messages, L is an integer and is not less than 0 and not more than N, the number of times of the second non-response is the number of times that the network device does not receive P response messages in the second period, the P response messages are P response messages in the N response messages, P is an integer and is not less than 0 and not more than N-L, and the first period and the second period are two consecutive periods.

For example, it is assumed that the period a and the period B are two consecutive periods, and the network device sends 3 authentication request messages, which are an authentication request message a, an authentication request message B, and an authentication request message C, respectively. The authentication request message A corresponds to the response message A, the authentication request message B corresponds to the response message B, and the authentication request message C corresponds to the response message C. The network device does not receive the response message a in the period a, and does not receive the response message B in the period B. In this case, the number of first non-responses is 1, and the number of second non-responses is 1.

For example, it is assumed that the period a and the period B are two consecutive periods, and the network device sends 3 authentication request messages, which are an authentication request message a, an authentication request message B, and an authentication request message C, respectively. The authentication request message A corresponds to the response message A, the authentication request message B corresponds to the response message B, and the authentication request message C corresponds to the response message C. The network device does not receive the response message a in the period a, and does not receive the response message B and the response message C in the period B. In this case, the number of first non-responses is 1, and the number of second non-responses is 3.

In the embodiment of the present application, the period lengths of the first period and the second period are not particularly limited.

As one implementation, the length of the period may be a predefined length. For example, the period length of the first period is 1, 2, 3, \8230:, N minutes, N is a positive integer of 1 or more.

As another implementation, the length of the period is set according to an application scenario. For example, the cycle length in a scenario where the network device accesses more users may be smaller than the cycle length in a scenario where the network device accesses less users.

Step 130, the network device detects the state of the server according to the first information or the second information.

In this embodiment, the detecting, by the network device, the state of the server according to the first information or the second information includes:

under the condition that the network equipment acquires the first information before acquiring the second information, the network equipment detects the state of the server according to the first information; alternatively, the first and second liquid crystal display panels may be,

That is, the network device may detect the state of the server based on the information acquired first.

It should be noted that after the network device acquires the first information, the network device does not continue to acquire the second information.

Illustratively, when the network device first acquires the first information at time T1, the network device detects the state of the server according to the first information. And after the time T1, the network equipment does not acquire the second information any more and clears the content of the previously acquired part of the second information.

Illustratively, when the network device first acquires the second information at time T1, the network device detects the state of the server according to the second information. And after the time T1, the network equipment does not acquire the first information any more and clears the content of the first information of the previously acquired part.

In some embodiments, in a case where the network device acquires the first information before acquiring the second information, the network device detects a state of the server according to the first information, including:

in the first time and the second time, under the condition that the network device does not receive Q response messages, the network device detects the state of the server according to the second time and the first time, including:

detecting that the server is in an off-line state under the condition that the difference between the second time and the first time is greater than or equal to the preset time; alternatively, the first and second electrodes may be,

detecting that the server is in an online state under the condition that the difference between the second time and the first time is less than the preset time;

q response messages are Q response messages in the N response messages, Q is a positive integer, and Q is more than or equal to 0 and less than or equal to N-2.

That is, in the first time and the second time, the state of the server may be detected by using the method described above when the network device does not receive one or more response packets.

In the embodiment of the application, the network device does not receive Q response messages in the first time and the second time, which can be understood as that, in the first time and the second time, the server sends Q response messages to the network device, and the network device does not receive the Q response messages, Q is a positive integer, and Q is greater than or equal to 0 and less than or equal to N-2. In the embodiment of the present application, the size of the preset time is not particularly limited. For example, the preset time may be set empirically, such as the preset time may be 8, 10, 11, 13, 15, 20 seconds, etc.

In other embodiments, in a case where the network device acquires the first information before acquiring the second information, the detecting, by the network device, the state of the server according to the first information includes:

in the first time and the second time, the network device receives Q response messages, and detects the state of the server according to the first time and the second time under the condition that K response messages are not received, including:

adjusting the third time to the first time, wherein the third time is the time corresponding to the time when the network equipment does not receive one response message in the K response messages for the first time after receiving the Q response messages;

the network equipment receives the Q response messages, wherein the Q response messages are Q response messages in the N response messages, Q is a positive integer, Q is not less than 1 and not more than N-2-K, the K response messages are K response messages in the N response messages, and at least one response message in the K response messages is a response message which is not received after the network equipment receives the Q response messages.

In this embodiment of the present application, the third time is a time corresponding to a time when the network device does not receive one response packet of the K response packets for the first time after receiving the Q response packets.

For example, during the first time and the second time, the network device receives a response message a first, and does not receive a response message B thereafter. In this case, the time corresponding to the non-reception of the response message B is the third time.

For example, in the first time and the second time, the network device receives a response packet a first, and then does not receive a response packet B and a response packet C, respectively. In this case, the time corresponding to the non-reception of the response message B is recorded as the third time.

For example, the network device does not receive the response message a, then receives the response message B, and then does not receive the response message C during the first time and the second time. In this case, the time corresponding to the non-reception of the response message C is the third time.

In this embodiment of the present application, at least one response packet in the K response packets is a response packet that is not received after the network device receives Q response packets.

Illustratively, Q =3, k =2 during the first time and the second time. That is, the network device receives 3 response messages in the first time and the second time, and the response messages are respectively marked as a response message a, a response message B and a response message C; the network device does not receive 2 response messages, and the response messages are respectively marked as a response message D and a response message E. In this case, the response packet D and/or the response packet E may be a response packet that is not received after the network device receives 3 response packets.

In some embodiments, in a case that the network device acquires the second information before the network device acquires the first information, the detecting, by the network device, the state of the server according to the second information includes:

detecting that the server is in an off-line state under the condition that the number of times of the first no response is greater than or equal to a first threshold value and the number of times of the second no response is greater than or equal to the first threshold value; alternatively, the first and second electrodes may be,

detecting that the server is in an online state under the condition that the number of times of the first no response is greater than or equal to a first threshold value and the number of times of the second no response is less than the first threshold value; alternatively, the first and second liquid crystal display panels may be,

and detecting that the server is in an online state under the condition that the number of times of the first no response is less than a first threshold value and the number of times of the second no response is greater than or equal to the first threshold value.

Illustratively, the first threshold is set to 5, the number of times of acquiring the first non-response is 6, and the number of times of acquiring the second non-response is 6. In this case, it may be detected that the server is in an offline state.

Illustratively, the first threshold is set to 5, the number of times of acquiring the first non-response is set to 3, and the number of times of acquiring the second non-response is set to 6. In this case, it may be detected that the server is online.

In the embodiment of the present application, the first threshold may be set according to experience or application scenarios. For example, the first threshold is 3, 4, 5, 6, 7, \ 8230 \ 8230;, N, etc., with N being a positive integer.

The method for detecting the server comprehensively considers the number of times of non-response of the server in a unit period and the duration of the non-response of the server, and detects the state of the server. Compared with the existing method for detecting the server, the method for detecting the server has higher accuracy in detecting the state of the server in different application scenes (for example, scenes that fewer users or more users are accessed in network equipment).

Fig. 2 illustrates an embodiment of a case where a network device receives a response packet in a first time and a second time according to the embodiment of the present application. It should be understood that fig. 2 is illustrative only and does not limit the present application in any way. For example, the network device may receive more response messages or may not receive more response messages during the first time and the second time.

As shown in fig. 2, "X" indicates that the network device does not receive a response message, "a" indicates that the network device receives a response message. The network device does not receive the response message a at the time t1, does not receive the response message B at the time t3, receives the response message C at the time t4, does not receive the response message D at the time t5, and does not receive the response message E at the time t2. Wherein t1< t3< t4< t5< t2.

Next, a method for detecting a server status according to an embodiment of the present application is described with reference to fig. 2 and fig. 3.

Fig. 3 shows a schematic flow chart of a method 300 for detecting a server status according to an embodiment of the present application.

As shown in fig. 3, the method 300 for detecting the server status includes steps 310 to 330, which are described in detail below.

For ease of understanding, the method 200 for detecting the server is described in the embodiment of the present application by taking N as 5, q as 1, and k as 2 as an example.

In step 310, the network device sends N authentication request messages.

Wherein, N is 5, and the 5 authentication request messages are an authentication request message a, an authentication request message B, an authentication request message C, an authentication request message D, and an authentication request message E, respectively. The response message a corresponds to the authentication request message a, the response message B corresponds to the authentication request message B, the response message C corresponds to the authentication request message C, the response message D corresponds to the authentication request message D, and the response message E corresponds to the authentication request message E. Specifically, referring to fig. 2, the network device does not receive the response packet a at time t1, does not receive the response packet B at time t3, receives the response packet C at time t4, does not receive the response packet D at time t5, and does not receive the response packet E at time t2. Wherein t1< t3< t4< t5< t2.

In step 320, the network device obtains the first information.

Wherein the first information comprises a first time and a second time.

The method for obtaining the first time and the second time is the same as the method in step 120 and step 130, and for brevity, detailed description is omitted here.

According to the method of step 120, the network device first determines t1 as a first time and t2 as a second time. As can be seen from the method of step 130, the first time needs to be updated in the embodiment of the present application. Specifically, the third time is adjusted to the first time. As can be seen from fig. 2, the third time is t5. Therefore, t5 in fig. 2 is a first time, and t2 is a second time.

In step 330, the network device detects the state of the server according to the first information.

In this embodiment, the method for the network device to detect the state of the server according to the first information is the same as the method in step 130, and details are not described herein for brevity.

According to the first time t5 and the second time t2 determined in step 320, detecting the state of the server includes:

when the difference between t5 and t2 is greater than or equal to the preset time, detecting that the server is in an off-line state; alternatively, the first and second liquid crystal display panels may be,

and when the difference between t5 and t2 is less than the preset time, detecting that the server is in an online state.

According to the method for detecting the server, the state of the server can be detected according to the duration of the non-response of the server.

Fig. 4 shows a schematic flow chart of a method 400 of detecting server status provided by the present application.

As shown in fig. 4, the method 400 for detecting the server status includes steps 410 to 440, which will be described in detail below.

In step 410, the network device sends N authentication request messages.

The method of step 410 is the same as that of step 110, and for brevity, will not be described in detail here.

In step 420, the network device obtains the first information and the second information.

The first information comprises a first time and a second time, and the second information comprises the first unresponsive times and the second unresponsive times. The method for acquiring the first information and the second information in step 410 is the same as the method for acquiring the first information and the second information in step 120 and step 130, and for brevity, detailed description is omitted here.

In step 430, whether the network device acquires the first information before acquiring the second information is determined.

In this embodiment of the present application, whether the network device acquires the first information before acquiring the second information includes:

when the first information is acquired before the network device acquires the second information, after step 430, step 440 is executed; alternatively, the first and second electrodes may be,

if the first information is not acquired before the network device acquires the second information, step 450 is executed after step 430.

Before the network device acquires the second information, the first information is not acquired. That is, the network device acquires the second information first. In other words, the second information is acquired before the network device acquires the first information.

Step 440, the network device detects the state of the server according to the first information.

The method of step 440 is the same as that of step 130, and therefore, for brevity, the detailed description thereof is omitted here.

Step 450, the network device detects the state of the server according to the second information.

The method of step 450 is the same as that of step 130, and therefore, for brevity, will not be described in detail here.

The method for detecting the server comprehensively considers the number of times of non-response of the server in a unit period and the duration of the non-response of the server, and detects the state of the server. Compared with the existing method for detecting the server, the method for detecting the server has higher accuracy in detecting the state of the server in different application scenes (for example, scenes with fewer users or more users accessed in the network equipment).

It should be understood that the methods of fig. 2-4 are illustrative only and are not limiting upon the present application. For example, the network device may also acquire only the first information, and detect the state of the server according to the first information.
