Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

The method for switching the IP resources of the main machine and the standby machine can be applied to an application environment shown in figure 1. Wherein, the standby machine 102 and the host machine 104 communicate by sending heartbeat information through a network. Both the standby 102 and the host 104 may be servers. During the operation of the host, the standby machine is in a standby state, the host and the standby machine share the same public IP, and when the host fails, the IP resource of the host can be switched to the standby machine, and the standby machine continues to provide service.

In one embodiment, as shown in fig. 2, a method for switching IP resources of a primary and a secondary computers is provided, and the method is applied to the secondary computers in fig. 1 for illustration, and includes the following steps:

s202, detecting the running state of software in the standby machine, and sending heartbeat information of the standby machine to the host machine according to a preset time interval; the heartbeat information of the standby machine comprises the running state of software in the standby machine.

Wherein, the heartbeat information (i.e. heartbeat package) is used for sending the state of the heartbeat information to the opposite party at regular time between the host and the standby. The heartbeat information is sent at preset time intervals. The running state of the software in the standby machine is the running state of the software which needs to monitor the running state in the preset standby machine. The running state of the software is the running process of the software.

In one embodiment, a user may preset at least one piece of software in the machine that needs to monitor the operating state. It can be understood that the software in the preset equipment needs to monitor the running state, which is all or part of the software in the equipment.

In one embodiment, the running state of the software in the standby may include normal and abnormal.

Specifically, the standby machine detects the running state of software in the preset standby machine, which needs to monitor the running state, and sends heartbeat information of the standby machine to the host machine at regular intervals. The heartbeat information of the standby machine comprises the detected running state of software in the preset standby machine, wherein the running state of the software needs to be monitored.

S204, receiving heartbeat information of the host returned by the host in response to the heartbeat information of the standby; the heartbeat information of the host computer comprises the running state of software in the host computer.

The running state of the software in the host is the running state of the software in the preset host, which needs to be monitored.

In one embodiment, the user may preset at least one software in the host that needs to monitor the operating state. It can be understood that the software in the preset host that needs to monitor the running state is all or part of the software in the host.

In one embodiment, the running state of software in the host may include normal and abnormal.

Specifically, after receiving heartbeat information of the standby machine sent by the standby machine, the host machine responds to the heartbeat information of the standby machine, detects the running state of software in the host machine, and feeds back the heartbeat information of the host machine to the standby machine. The heartbeat information of the host computer comprises the detected running state of software in the preset host computer, wherein the running state of the software needs to be monitored. The standby machine receives the heartbeat information of the host machine returned by the host machine in response to the heartbeat information of the standby machine.

S206, detecting the public IP.

In one embodiment, detecting the public IP may include processing to read the IP local to the standby to confirm whether the public IP is on standby, and to detect whether the public IP is accessible (i.e., whether the public IP is online).

In one embodiment, the standby may remain detecting public IP at all times.

S208, when the heartbeat communication ratio with the host computer is 100% in the preset time period, and the public IP is detected to be not in the standby computer and the running state of software in the host computer is abnormal, switching the public IP to the standby computer; the heartbeat communication ratio is a ratio between the number of times heartbeat information of the host is actually received in a preset time period and the number of times heartbeat information of the host, which is returned, should be received by sending the heartbeat information of the standby at preset time intervals.

The preset time period is a preset time period for judging whether to switch the IP resources, namely, if the condition of switching the IP resources is met in the preset time period, the IP resources are switched; if the condition of switching the IP resources is not met, the IP resources are not switched, the timing is repeated, whether the condition of switching the IP resources is met in a preset time period is judged, and the like.

In one embodiment, the preset time period may be set according to the requirement, for example, the preset time period may be set to 5 seconds or 4 seconds, etc.

Specifically, when the following three conditions are simultaneously satisfied within a preset period of time: 1. the heartbeat communication ratio with the host is 100%, namely, the standby machine sends the heartbeat information of the standby machine to the host according to the preset time interval in the preset time period, and the heartbeat information of the host returned by the host can be received each time; 2. the standby machine detects that the public IP is not in the standby machine as a result of detecting the public IP; 3. the running state of software in the host computer contained in the heartbeat information of the host computer received by the standby computer is abnormal, and the standby computer switches the public IP to the standby computer (namely, the standby computer is connected with the public IP).

As shown in fig. 3, an overall flow chart of the method for the standby machine to perform the primary-standby machine IP resource switching is shown. The method in this embodiment corresponds to the method in fig. 3 that the heartbeat communication ratio between the standby machine and the host machine is 100% in the preset time period, and detects the public IP, and when detecting that the public IP is not in the standby machine and the running state of the software in the host machine is abnormal, switches the public IP to the standby machine, which is a flow path.

In one embodiment, when the heartbeat communication ratio of the standby machine and the host machine is 100% in the preset time period, and it is detected that the public IP is not in the standby machine and the running state of software in the host machine is normal, the standby machine does not switch the public IP until the running state of the software in the host machine contained in the received heartbeat information of the host machine is abnormal, and then the public IP is switched to the standby machine.

In the above method for switching the IP resources of the host and the standby machine, the running state of the software in the standby machine is detected, the heartbeat information of the standby machine including the running state of the software in the standby machine is sent to the host machine according to the preset time interval, then the heartbeat information of the running state host machine including the software in the host machine returned by the host machine in response to the heartbeat information of the standby machine is received, and when the heartbeat communication ratio with the host machine is 100% in the preset time period, and it is detected that the public IP is not in the standby machine and the running state of the software in the host machine is abnormal, the public IP is switched to the standby machine. The heartbeat information of the host comprises the running state of software in the host, so that the running state of the host can be determined according to whether the heartbeat information can be received or not, the running state of the host can be determined more accurately according to the running state of the software in the host, and the public IP can be detected, so that the IP resources of the host and the IP resources of the host can be switched in time according to the running state of the software in the host and the state of the public IP, and the accuracy of switching the IP resources of the host and the backup is improved. In addition, in the preset time period, when the preset switching condition is met, the IP resources can be switched in time, excessive time is not required to be consumed, and the failure of timely switching is caused, so that the IP resources of the main machine and the standby machine can be further ensured to be timely switched. In addition, according to the software running state in the heartbeat information, the public IP is switched in time, so that the loss of data in the switching process caused by the too slow public IP switching can be avoided, and the integrity of the data is ensured.

In one embodiment, the method further comprises the steps of: and when the heartbeat communication ratio with the host computer is 100% in the preset time period and the public IP is detected to be in the standby computer and the running state of software in the host computer is normal, removing the public IP from the standby computer.

Specifically, the standby machine may detect the public IP, and when the following 3 conditions are satisfied simultaneously within a preset period: 1. the heartbeat communication ratio of the standby machine to the host machine is 100%, namely, the standby machine sends heartbeat information of the standby machine to the host machine according to a preset time interval in a preset time period, and the heartbeat information of the host machine returned by the host machine can be received each time; 2. the standby machine detects that the public IP is in the standby machine; 3. when the running state of software in the host computer contained in the heartbeat information of the host computer received by the standby computer is normal, based on the principle of ensuring the normal service of the host computer preferentially, the public IP is removed from the standby computer (namely, the standby computer breaks the connection of the public IP), so that the host computer can normally connect the public IP, and the public IP connection conflict caused by the simultaneous connection of a plurality of servers to the public IP is avoided.

The method in this embodiment corresponds to the method in fig. 3, in which the heartbeat communication ratio between the standby machine and the host machine is 100% in the preset period, and detects the public IP, and when detecting that the public IP is in the standby machine and the running state of the software in the host machine is normal, the public IP is removed from the standby machine, which is a flow path.

In one embodiment, when the standby machine and the heartbeat communication ratio of the host machine are 100% in a preset time period, and it is detected that the public IP is in the standby machine and the running state of software in the host machine is abnormal, the public IP is not removed from the standby machine until the running state of the software in the host machine contained in the received heartbeat information of the host machine is normal, and the public IP is removed from the standby machine.

In this embodiment, when the standby machine and the heartbeat communication ratio of the host machine are 100% in the preset time period, and it is detected that the public IP is in the standby machine and the running state of software in the host machine is normal, the public IP is removed from the standby machine, and the service of the host machine is preferentially ensured under the normal state of software in the host machine, so that the host machine can be normally connected with the public IP, and the public IP connection conflict caused by that a plurality of servers are simultaneously connected with the public IP is avoided. In addition, the IP resources of the main machine and the standby machine can be switched in time according to the running state of software in the main machine and the detected public IP state. In addition, in the preset time period, when the preset switching condition is met, the IP resources can be switched in time, excessive time is not required to be consumed, and the failure of timely switching is caused, so that the IP resources of the main machine and the standby machine can be further ensured to be timely switched.

In one embodiment, the heartbeat information of the standby further includes a first public IP resource status. The first public IP resource status is used to characterize whether the public IP is on standby. After the step of removing the public IP from the standby, the method further comprises the steps of: generating heartbeat information of the standby machine and feeding back the heartbeat information to the host machine; the first public IP resource state in the heartbeat information of the standby machine fed back represents that the public IP is not on the standby machine; the first public IP resource state is used for indicating the host to switch the public IP to the host when the access loss rate of the public IP detected in the preset time period is greater than or equal to a preset access loss rate threshold value.

The access loss rate is a ratio between the number of times that the public IP is not accessed within a preset period of time and the total number of times that the public IP is attempted to be accessed. It will be appreciated that the total number of attempts to access the public IP includes the number of times the public IP was not accessed and the number of times the public IP was accessed. The preset access loss rate threshold is a preset threshold condition for determining that the public IP is not on-line (i.e., the public IP is not connected to the host and the standby) when the access loss rate is greater than or equal to the threshold.

In one embodiment, the first public IP resource status may include public IP on standby and public IP off standby.

Specifically, the standby machine may send heartbeat information to the host machine at regular intervals, and after the public IP is removed from the standby machine, the first public IP resource state in the heartbeat information generated by the standby machine and sent to the host machine characterizes that the public IP is not on the standby machine. The host may switch the public IP to the host (i.e., the host connects the public IP) when detecting that the access loss rate of the public IP is greater than or equal to a preset access loss rate threshold (i.e., it is determined that the public IP is not on-line) within a preset period of time after receiving heartbeat information sent by the standby that includes a status of a first public IP resource that characterizes the public IP is not on the standby.

In this embodiment, the heartbeat information of the standby machine further includes a first public IP resource state for indicating whether the public IP is in the standby machine, so that after the public IP is removed from the standby machine, the standby machine can feed back to the host machine that the public IP is not in the standby machine through the heartbeat information, and the standby machine can switch the public IP to the host machine in time according to the heartbeat information fed back by the standby machine. In addition, the host detects the public IP, and can further confirm that the public IP is not on-line, so that the public IP connection conflict caused by that a plurality of servers are simultaneously connected with the public IP is avoided. In addition, in the preset time period, when the preset switching condition is met, the IP resources can be switched in time, excessive time is not required to be consumed, and the failure of timely switching is caused, so that the IP resources of the main machine and the standby machine can be further ensured to be timely switched.

In one embodiment, the method further comprises the steps of: and when the heartbeat packet loss rate in the preset time period is greater than or equal to a preset heartbeat packet loss rate threshold value and the access loss rate of the public IP is detected to be greater than or equal to a preset access loss rate threshold value, switching the public IP to the standby machine.

The heartbeat packet loss rate is a ratio between the number of times that the heartbeat information of the host is not received in a preset time period and the number of times that the heartbeat information of the host, which is returned by sending the heartbeat information of the standby according to a preset time interval, is supposed to be received.

Specifically, after the standby machine sends heartbeat information of the standby machine to the host machine, when the heartbeat packet loss rate in a preset time period is greater than or equal to a preset heartbeat packet loss rate threshold value, the host machine indicates that a problem is likely to exist, and when the standby machine detects that the access loss rate of the public IP is greater than or equal to the preset access loss rate threshold value in the preset time period, the public IP is switched to the standby machine (namely, the standby machine is connected with the public IP).

The method in this embodiment corresponds to a flow path in fig. 3, where when the heartbeat packet loss rate of the standby machine in the preset time period is greater than or equal to the preset heartbeat packet loss rate threshold, and the access loss rate of the public IP detected by the public IP is greater than or equal to the preset access loss rate threshold (i.e., the public IP is not online), the public IP is switched to the standby machine.

In this embodiment, when the heartbeat packet loss rate of the standby machine in the preset time period is greater than or equal to the preset heartbeat packet loss rate threshold, the standby machine can determine that there is a possibility that the host machine has a problem in time, because the standby machine cannot receive the heartbeat information and cannot determine the running state of software in the host machine and whether the IP is in the host machine, the standby machine can determine whether to switch the public IP by detecting the public IP, and when the standby machine detects that the public IP is not online, the standby machine can switch the public IP to the standby machine in time. In addition, in a preset time period, when preset switching conditions are met, the IP resources can be switched in time, excessive time is not required to be consumed, and the fact that the IP resources of the main machine and the standby machine cannot be switched in time is further guaranteed.

In one embodiment, the method further comprises the steps of: and when the heartbeat packet loss rate in the preset time period is greater than or equal to a preset heartbeat packet loss rate threshold value and the access loss rate of the public IP is detected to be smaller than a preset access loss rate threshold value, continuing to detect the public IP until the access loss rate of the public IP in the preset time period is greater than or equal to the preset access loss rate threshold value, and switching the public IP to the standby machine.

Specifically, after the standby machine sends heartbeat information of the standby machine to the host machine, when the heartbeat packet loss rate in a preset time period is greater than or equal to a preset heartbeat packet loss rate threshold value, the host machine indicates that a problem is likely to exist, when the standby machine detects that the access loss rate of the public IP is smaller than the preset access loss rate threshold value (namely, the public IP is judged to be online) and the public IP is not in the standby machine in the preset time period, the public IP is continuously detected (the public IP is not switched) until the access loss rate of the public IP is greater than or equal to the preset access loss rate threshold value (namely, the public IP is judged to be not online) in the preset time period, and the public IP is switched to the standby machine.

It can be understood that when the heartbeat packet loss rate in the preset time period is greater than or equal to the preset heartbeat packet loss rate threshold, it indicates that there is a possibility that the host has a problem, but by detecting the public IP, it detects that the public IP is online and the public IP is not in the standby for the preset time period, which indicates that the host is normally connected with the public IP, the host has no problem, so the standby does not switch the public IP, continues to detect the public IP, and does not switch the public IP to the standby until the public IP is not online for the preset time period.

It can be understood that the heartbeat packet loss rate in the preset time period is greater than or equal to the preset heartbeat packet loss rate threshold, but the public IP is detected to be online and not in the standby, which may be caused by that the standby cannot receive the heartbeat information of the host due to the fact that the host is provided with a firewall and the like.

The method in this embodiment corresponds to a flow path in which the heartbeat packet loss rate of the standby machine in fig. 3 in a preset time period is greater than or equal to a preset heartbeat packet loss rate threshold, then the public IP is detected, and when the public IP is detected to be online and the public IP is not in the standby machine, the public IP is continuously detected.

In one embodiment, when the heartbeat packet loss rate of the standby machine in the preset time period is greater than or equal to the preset heartbeat packet loss rate threshold value, the public IP is detected, and when the access loss rate of the public IP is detected to be smaller than the preset access loss rate threshold value (i.e. the public IP is judged to be online) and the public IP is in the standby machine, the standby machine does not switch the public IP (i.e. the standby machine is kept connected with the public IP).

In this embodiment, when the heartbeat packet loss rate of the standby machine in the preset time period is greater than or equal to the preset heartbeat packet loss rate threshold, the public IP is detected, when the public IP is detected to be online and the public IP is not in the standby machine, the host machine is determined to have no problem, and the public IP is continuously detected until the public IP is not online in the preset time period, and the public IP is switched to the standby machine. The public IP is not switched on one-sided basis on whether heartbeat information is received or not, and the state of the host is further confirmed by detecting the public IP, so that the public IP can be switched more accurately, and the error switching of the public IP is avoided.

In one embodiment, as shown in fig. 4, a method for switching IP resources of a host and a standby is provided, and the method is applied to the host in fig. 1 for illustration, and includes the following steps:

s402, receiving heartbeat information of the standby machine, which is sent by the standby machine according to a preset time interval; the heartbeat information of the standby machine comprises the running state of software in the standby machine.

Specifically, the standby machine detects the running state of software in the preset standby machine, which needs to monitor the running state, and sends heartbeat information of the standby machine to the host machine at regular intervals. And the host receives the heartbeat information of the standby machine, which is sent by the standby machine. The heartbeat information of the standby machine comprises the detected running state of software in the preset standby machine, wherein the running state of the software needs to be monitored.

S404, responding to the heartbeat information of the standby machine, detecting the running state of software in the host machine, and sending the heartbeat information of the host machine to the standby machine; the heartbeat information of the host computer comprises the running state of software in the host computer.

Specifically, the host responds to the heartbeat information of the standby machine, detects the running state of software in the host, and sends the heartbeat information of the host to the standby machine. The heartbeat information of the host computer comprises the detected running state of software in the preset host computer, wherein the running state of the software needs to be monitored.

It can be understood that, if the heartbeat information of the standby machine received by the host machine includes information of which type, the host machine responds to the heartbeat information of the standby machine, and feeds back the heartbeat information including information of the corresponding type to the standby machine.

S406, detecting the public IP.

In one embodiment, detecting the public IP may include reading the IP local to the host to confirm whether the public IP is on the host, detecting whether the public IP is accessible (i.e., whether the public IP is online), and so on.

In one embodiment, the host may keep detecting public IP at all times.

S408, when the running state of the software in the host is abnormal in the preset time period and the public IP is detected to be in the host, the public IP is removed from the host.

Specifically, when the host detects that the running state of software in the host is abnormal and that the public IP is in the host within a preset period of time, the public IP is removed from the host (i.e., the host disconnects the public IP).

In one embodiment, the heartbeat information of the host further includes a second public IP resource status. The second public IP resource status is used to characterize whether public IP is on the host. And when the host detects that the running state of software in the host is abnormal in a preset time period, removing the public IP from the host, and sending a second public IP resource state which characterizes that the public IP is not in the host to the standby through heartbeat information. And the standby machine determines that the running state of software in the host machine is abnormal and the public IP is not in the host machine according to the received heartbeat information of the host machine, detects the public IP, and switches the public IP to the standby machine (namely, the standby machine is connected with the public IP) when the access loss rate of the public IP in a preset time period is larger than or equal to a preset access loss rate threshold value and the public IP is not in the standby machine.

Fig. 5 is a schematic overall flow chart of a method for executing the IP resource switching between the host and the standby. The method in this embodiment corresponds to a flow path in which the host removes the public IP from the host when the running state of the software in the host in fig. 5 is abnormal.

In the above method for switching the IP resources of the host and the standby machine, the host receives the heartbeat information of the standby machine, detects the running state of the software in the host in response to the heartbeat information of the standby machine, and sends the heartbeat information of the host including the running state of the software in the host to the standby machine. In addition, in a preset time period, when preset switching conditions are met, the IP resources can be switched in time, excessive time is not required to be consumed, and the fact that the IP resources of the main machine and the standby machine cannot be switched in time is further guaranteed.

In one embodiment, the method further comprises the steps of: and when the running state of software in the host is normal within the preset time period, the public IP is detected to be not in the host, and the access loss rate of the public IP is greater than or equal to the preset access loss rate threshold value, switching the public IP to the host.

Specifically, when the following 3 conditions are simultaneously satisfied within a preset period of time: 1. the host detects that the running state of software in the host is normal; 2. the host detects that the public IP is not in the host; 3. and if the host detects that the access loss rate of the public IP is greater than or equal to a preset access loss rate threshold (i.e. the public IP is judged to be not on-line), the public IP is switched to the host (i.e. the host is connected with the public IP).

The method in this embodiment corresponds to a flow path in which the running state of software in the host in fig. 5 is normal, and when the host detects that the public IP is not on-line, the public IP is switched to the host.

In one embodiment, when the running state of software in the host is normal and the host detects that the public IP is on-line and the public IP is on the host, then the public IP is not switched (i.e., the host remains connected to the public IP).

In this embodiment, the host computer can switch the public IP to the host computer in time according to the running state of the software in the host computer and the state of the public IP.

In one embodiment, the heartbeat information of the host further includes a second public IP resource status. The second public IP resource status is used to characterize whether public IP is on the host. The method further comprises the steps of: when detecting that the public IP is not in the host computer in a preset time period and the access loss rate of the public IP is smaller than a preset access loss rate threshold value, generating heartbeat information of the host computer and feeding back the heartbeat information to the standby computer; the second public IP resource state in the heartbeat information of the fed back host characterizes that the public IP is not in the host; the second public IP resource state is used for indicating the standby machine to remove the public IP from the standby machine when the standby machine detects that the public IP is in the standby machine; and continuing to detect the public IP until the access loss rate of the public IP is greater than or equal to a preset access loss rate threshold value in a preset time period, and switching the public IP to the host.

In one embodiment, the second public IP resource status may include public IP on-host and public IP off-host.

Specifically, when the following three conditions are simultaneously satisfied within a preset period of time: 1. the host detects that the running state of software in the host is normal; 2. the host detects that the public IP is not in the host; 3. when the host detects that the access loss rate of the public IP is smaller than a preset access loss rate threshold (namely, the public IP is judged to be online), the second public IP resource state in the heartbeat information fed back to the host of the standby machine represents that the public IP is not in the host. The standby machine receives the heartbeat information of the host machine sent by the host machine, determines that the running state of software in the host machine is normal and the public IP is not in the host machine according to the heartbeat information of the host machine, continues to detect the public IP, and removes the public IP from the standby machine when the standby machine detects that the public IP is in the standby machine (namely, the standby machine breaks the connection of the public IP). The host continues to detect the public IP until it is detected that the access loss rate of the public IP is less than the preset access loss rate threshold (i.e., it is determined that the public IP is not on-line and the standby has removed the public IP), then the public IP is switched to the host (i.e., the host connects the public IP).

In this embodiment, when the host detects that the public IP is not in the host and the public IP is online, heartbeat information including a second public IP resource state indicating that the public IP is not in the host is generated and fed back to the standby machine, so that the standby machine timely removes the public IP from the standby machine according to the second public IP resource state in the heartbeat information of the host and the state of software in the host. The host detects through the public IP, and when detecting that the public IP is not on-line, the host can switch the public IP to the host in time.

Fig. 6 is a schematic diagram of interaction between a host and a standby machine in each embodiment of the present application, where the host and the standby machine send heartbeat information to each other, and send a software state (i.e. an operation state of software in the host and the standby machine) through the heartbeat information, and both the host and the standby machine can detect a public IP.
